1. Introduction
The processes of treatment of most of worn waters produce a vase that must is liquidated. The plants of treatment of drains conventional secondary produce typically a primary vase in the step of primary sedimentation of treatment and a secondary, biological, the vase in the final sedimentation after the biological process. The characteristics of the secondary vase change according to the type of biological process, and often it is mixed with the primary vase before the treatment and before the disposal. Roughly a half of the costs of plants of treatment of drains secondary operating can be associated in Europe with the treatment of vase and the disposal. Land the application of vase of drains believed or treated can reduce significantly the component of cost of disposal of vase of treatment of drains just like to furnish a big party of the conditions of nitrogen and phosphorus of a lot of harvests. Very rarely to do the urban systems of worn waters transport drains only servant to the treatment plants; the industrial effluents and the streaming of orage-eau of the roads and other paved sectors frequently are unloaded in the sewers. Thus the vase of drains will contain, what's more equipment of organic waste, the tracks of a lot of used pollutants in our modern corporation. Certain of these substances can be phytotoxic and some poisons to the humans and/or the animals if it are necessary to check the concentrations in the ground of elements potentiellesment toxic (PTE) and their application rate to the ground. The risk to the health of chemical products in the vase of drains is applied to land was reconsidered itself by Dean and Suess1
The vase of drains contains also pathogenic bacteria, the viruses and the protozoaire with other parasitic helminths that can generate potential dangers to the health of humans, the animals and the plants. A THAT (1981) the Report on the risk to microbe health in the vase of drains is applied to land itself salmonellas and identified Taenia as generating the biggest worry. The numbers of pathogenic and parasitic organisms in the vase significantly can be reduced before the application to the earth by the treatment of fitting vase and the risk of health potentielle more is reduced by the climate effects, the grounds microorganisms and stopwatch after the vase is applied to the ground. Nevertheless, in the case of certain harvests, the limitations on the plant, grazing and harvest is necessary.
Outside of these worry components, the vase of drains contains also useful concentrations of nitrogen, phosphorus and the organic question. The availability of the content of phosphorus in the year of application is about 50% and is independent treatment of previous vase. Nitrogen availability is dependenter on the vase treatment, the vase and liquid dewatered non-treaties treated vase relaxing nitrogen slowly with the advantages to the harvests is realized on a comparatively long period. The vase of anaedrobiquement-digedred of liquid has contained top of ammoniaque-azote that is easily available to the plants and can be special advantage to the prairie. The organic question in the vase can improve water keeping the capacity and the structure of some grounds, especially when applied in the form of a cake of vase of dewatered.
2. Which is vase?
Residual, biosolids, septage, drains it, the diverted product of worn waters, the compost: there are a lot of names for the products of vase and vase. The "vase" of term is used as most of the people understand it: equipment sometimes sometimes solid liquid produces by the plants of treatment of worn waters and used as the fertilizer on the fields, in the gravia¨res, and on the batches of exploitation of the forests through the state. The vase can classified as "Classifies ONE" if it was treated to reduce germs at the level of bottom (the levels found normally in the grounds) and "B of Class" if it was treated for that the germs are reduced by one estimated 90%.
3. The composition of vase of drains:
The nature of the vase of drains depends on the process of treatment of water of waste and on the source of drains it. Usually it contains toxic organic wastes and not toxic. Of the two, the non toxic composites are to understand the most current all equipment of plant and the animal origin, including the proteins, the amino acids, Sugar and the fatty one. The toxic organic composite understands aromatic hydrocarbons Nuclear Polish (PAHs), the phednols of alkyl, polychlorinated biphenyls (PCB) the organo-chlore pesticides, aromatic monocyclic, the chloro-benza¨nes, aromatic and alkyl amines, the dioxines of polychlorinated, the phednols etc. What's more of these wastes these organic vases of drains material contains also tracks of a lot of pollutants as the Copper, Zinc, the Nickel, the Cadmium, the Advance, the Arsenic, the Chrome, the Selenium etc. Certain of these substances can be phytotoxic and some poisons to the humans and/or the animals, therefore the it is necessary to check the concentrations in the ground of elements potentiellesment toxic and their application rate to the ground. The vase of drains contains also pathogenic bacteria, the viruses & the protozoaire with other parasitic helminthes that can generate potential dangers to the health of humans, the animals and the plants. Outside of these components of vase of drains worry contains also useful concentrations of N, P and the organic question. Every component of the vase has his own ecological impact, that must be taken into account while choosing the disposal road.

4. The vase treatment:
The urbanization and growing Industrializations had for result a dramatic increase in the volume of water of waste produced around the world. The step of treatment of water of waste concentrates the various pollutants (upto 90%) in waste water in the vase, containing normally between 1% and 2% by the dry weight of the solids. The treatment of water of waste ordinarily implies the following processes to treat the vase for the production of products of suitable end for the usage or the disposal:

The methods of treatment of vase
Treat the Description

Minimum of pasturization of vase of 30 minutes to 70ºC or the minimum of 4 hours to 55ºC (or appropriates intermediary conditions), followed in all cases by primary mesophilic the anaerobic digestion.

Mesophilic the anaerobic digestion period of Average retention of at least 12 days digestion primary in the temperature range 35ºC ± 3ºC or of atleast 20 days digestion primary in the temperature range 25ºC ± 3ºC followed in every case by a secondary step that furnishes a period of average retention of at least 14 days.

Thermophilic the aerobic digestion period of Average retention of at least 7 digestions of days. All vase to be liable to at least 55ºC for a period of at least 4 hours.

Punch The compost must be maintained to 40ºC for at least 5 days and for 4 hours during this period to at least 55ºC in the pile body followed by a period of sufficient maturation to guarantee that the process of reaction of compost is substantially complete.

The stabilization of files Addition of vase liquidates of files for high pH to bigger than 12.0 and sufficient to guarantee than the pH is not less than 12 for a period minimum of 2 hours. The vases can be used then directly.

Storage Emmagasinage liquidates liquid vase non-treaty for a period minimum of 3 months.

Dewatering and the emmagasinage Conditioning of non treated vase with files it or of coagulative others follow by dewatering and the cake emmagasinage for a period minimum of 3 months. If the vase was liable to primary mesophilic the emmagasinage of anaerobic digestion to be for a period minimum of 14 days.

5. Agricultural application
The application of vase of drains as a "the sure fertilizer "began in serious after the 1988 bans on the vase of drains of offloads losses in the ocean. When the Act of Ban of Offloads losses of Ocean of 1988 has entered in force, the municipalities & the Govts. left with a new problem ae" how to be ridded tons of vase that they produce on a daily basis. The agency of Protection Ecologique federal (EPA) has entered with a project of "to resolve" this problem in vase promouvoant (called sometimes "biosolids", a public relations name that is interchangeablement used by EPA with the technical term "the vase of drains") as the fertilizer to be spread out over the earth ae" where the life of people, the work and the game. Nevertheless, the nevertheless, sticky and black cake adds the free Organic Question & the Fertilizer to the poor grounds, the productive and profitable fact, the principal resultant limitations of such factors are: the pathogenic, the heavy metals, toxic organic. Therefore, the project of EPA allowed the toxic chemical products in the air, water, the ground, the harvests & in us. Then, call this "fertilizer" of vase is equivalent to call a "food" of soup that, although it contains some meat & the vegetables, contains also a little advances, a small arsenic, and a maybe hundreds or same thousands of other, toxic, organic and inorganic equipment of which the ranges of impact of cancedroga¨ne to teratogenic (the birth defect inducing). "Most of the people want a simple response; the good east or the bad east. The response is not so simple. The this is not completely risks it liberates, but it has advantages. Just as the driving of a car", Sanden said.

6. The problem of Vase
The vase contains measurable quantities of pollutants, as the heavy metals, as the dioxine, and as the other toxic chemical products. The vase contains also pathogenic -- the human germs, the bacteria, the viruses, and the parasites. And the vase odors: the vase odor is more just a boredom; the this is a threat of public health, that was linked up to the problems and the respiratory deaths. The application of earth of vase distributes pollutants of the big cities and the big cities to the rural sectors, far from which they were products at first. Declare of the and the federal agencies of various country regulate display of vase, but the regulation of this waste is difficult and problematic. A lot of scientists consent that the rules of application of current earth do not protect human health, the agricultural productivity, or the environment. The subsidy lack to furnish regulating correct oversight and the same nature of drains are anxious the account of the display of vase of an unknown quality to arrive on our earths.
The problems with the vase include:
? The vase contains heavy metals, the toxic chemical products, and the pathogenic ones.
? The essay and the vase regulation are inadequate and problematic.
? The vase odors put a threat of public health and lower the life quality.

7. The boredom with the vase
7.1. How the toxic vase becomes fertilizer
In the traditional agricultural corporations, the human waste often was used to enrich the ground. The Industrial Revolution caused increased the urbanization and the need for the cities to develop the systems of primitive sewer to remove human waste. The pipes and the gutters were constructed to offload drains it directly in our lakes, our rivers, and our oceans. As the industry increased in the World, the factories began using these systems of primitive sewer to be ridded of their waste. This practice continued well in the twentieth century, when the industry widely began using toxic chemical products. The usage of the system of local sewer as a ground of offloads losses for the toxic waste was an easy solution to their problems of disposal and was more inexpensive than to treat their waste on the site. Drains it loaded with the toxic chemical products public, major healths and created and the ecological disasters through the World: the rivers took the fire, the public drinks provisions of water became polluted, and the waste washed on our beaches. Public clamor of the number growing disasters took to the passage of the Act of federal Own Water in 1972. These norms of quality of water of series of act nationally and furnished money to the communities to improve the systems of sewer and creates opportunities of treatment of worn waters. Unfortunately, instead of addressing the problem root while stopping the usage and the industrial disposal of chemical toxic products, the act rather regulated the quantity of big pollution industries could relax in the sewer systems.
By the last years 70, the systems of drains vast had been constructed through the country. The plants of treatment of worn waters were constructed to separate losses cluttering with water, and, following the natural and chemical treatment, the water of relacchement of return in the environment, clean human waste. Unfortunately, they were not constructed to treat toxic chemical waste. While these systems of drains and the plants of treatment of worn waters improved the norms of public health and water the quality, they have an ironic defect. The treatment process creates own water but creates also a diverted toxic product: the vase. Indeed, the Own Act of Water correctly defines vase as a pollutant. As all waste, the vase must be liquidated in certain respects. What to do with the vase was a controversy source for the passed three decades in the World. By the years 70 and the years 80, the Agency of Protection Ecologique federal (EPA) regulated strictly the display of earth of vase, forbidding efficiently a good party of the waste of is used on the agricultural earth. The opportunities of treatment of worn waters could liquidate only vase in one of three manners: while the envoy to a disposal, while cremating it, or by offloads it losses it 100 miles at sea in the ocean. 2
Offloads it ocean losses created finally big dead sectors submarines. In response to the public worry, Congress passed the Act of Offloads losses of Ocean, that forbade offloads it losses of ocean of vase in 1992.3 disposals of Vase principally then was limited to the disposals and to the cremation that became dear for the plants of treatment of worn waters. The municipal opportunities of treatment then did pressure on the EPA to relax its norms for the earth spreading itself vase on the agricultural fields. Follow a number of untidy one rewrite regulations of EPA, the business vase putting on the market of the businesses and opportunities of treatment of worn municipal waters succeeded relaxing toxin limits in the vase for the earth display. Of qu'a-t-il been considered once the dangerous losses became a fertilizer? While classifying vase as a fertilizer, it became exempted of several regulations of treatment of the losses.
7.2. The marketing of toxic vase
The municipal opportunities of treatment of water depend on the brokers of vase of business to liquidate their vase. To liquidate it, these commercial private corporations convince farmers and the important owner through the country to spread vase on their fields as a nutritious supplement for their harvests. The vase is put on the market to the important owners and to the consumers in two different manners. The first one, and the most evident one, is while offering their liberates vase. While convincing the individual owners of property that the vase is of "the advantage of agronomic" to their earth, their vase brokers find the sites of extremely inexpensive disposal for the vase that would have otherwise are dispatched to the disposals or to the incinedrateurs to a cost of roughly $70 a ton. 4
The businesses claim while everyone wins: the treatment plants have an option of inexpensive disposal for their vase, that gives taxpayers a cut, and the important owners obtain from the free nutriments for their fields. As a precise result, the vase brokers walk far with the expenses of disposal of the ease of treatment. The vase brokers escape also of the responsibility potentielle, that now is supposed by the owner of farmer or property. The second vase in a manner is put on the market is while punching or palletizing it. Then it can be sold or can be distributed as punches of the or the fertilizer. Since the weakening of regulations of vase in the last years 80, the citizens cross the World-wide one fought to keep vase of is spread out over the fields and the cultures in their communities. The activists fighter of the vase is opponents against frightful. The opportunities of treatment of water and the vase brokers formed the groups of powerful commerce, as the New England Biosolids & the Residual Association (NEBRA). NEBRA, in the bend, is part of an equal one bigger and more powerful group: the Partnership of National Biosolids, that is a group coalition as the EPA and the Federation of Environment of Water, of which the primary responsibility is to change "the public perception" display of vase.
7.3. The toxic secrets of vase
The earth is applied vase is demanded laws to have toxic levels to the under certain limits and it is treated with files it to reduce the levels of pathogenic one. Nevertheless, no vase in World is completely free chemical products or of pathogenic poisons. Indeed, after it is treated, the vase of B of Class always contains a significant quantity of pathogens5.
7.4. Toxic in the vase
Has. Heavy Metals
All vase in the world contains heavy metals as the arsenic, the cadmium, the chrome, the copper, the advance, mercury, the molybda¨ne, the nickel, the selenium, and zinc. 6 These metals are persistantsae”qui is, they do not fall broken down in the environment and develop therefore progressively. As the Cornell the states of Co-operative Extension, "most of the heavy metals remain in the ground for the long periods of time, spreading of several decades to a lot of centuries". The heavy metals in the vase of broadcasting of earth become therefore permanent additions to the total quantity in the ground. Even the extremely small quantities of heavy metals in the vase, therefore, are dangerous. 7 High levels of arsenic in the food or water can be fatal. The cadmium, the chrome, the nickel, and the selenium was linked up to cancer. The cadmium also was linked up to the kidney problems, the miscarriages, and stillborn. The copper, the nickel, and zinc is known to cause problems of growth in the harvests. The children exposed to take can develop behavioral problems and of erudition. The mercury exposition to the moments keys in the fetal development can cause inabilities edruditiones and neurological disorders. Bioaccumulates of molybda¨ne in grass cattle food; ingested in the excess, it can cause weakens it, the diarrhea, and the growth problems. 8 These metals can be taken by the plants that are grown on the vase and returns the human food chain through the cattle nourishes. These metals can filter also in underground water. The grounds extremely acids, as these found in the Maine, can worsen filter of heavy metal. 9

B. Pathogenic: The bacteria, the Viruses, and the Parasites
The vase, by his same nature, contains pathogenic humans: the germs as the bacteria, the viruses, and the parasites. While the exposition to the heavy metals can cause problems progressively, the exposition to these germs is sharper and can cause the health problems almost immediately. Because of the extremely big numbers of pathogenic ones that exist in the world, it is impossible to try vase for all types of pathogenic ones. Some pathogenic common one in the vase include the e-coli of bacteria and the Salmonella, the virus Hepatitis ONE, and the towards parasitic. The pathogenic ones can cause intestinal problems, the other diseases, and the serious death. The vase of broadcasting of earth can be treated to fail to eliminate the pathogenic ones. While punching vase, for example, the levels of pathogenic one significantly can be reduced. Unfortunately, the federal laws and state allow "B of Class" the vase, that was not treated to the methods of reduction of pathogenic the strictest ones, to be spread. In of other terms, the vase with the pathogenic ones in life is spread through the state. Unfortunately for the inhabitants and the workers of New England of the north, the wet and obscured climates encourage the growth of pathogenic one. The researchers found that the pathogenic ones can survive in the vase for the weeks, the months, or even the years after the processes of treatment of reduction.
The humans can be exposed to the pathogenic ones of vase in a number in a manner. We could consume vegetables that have pathogenic on them. The children could win accidentally the access to a field of vase and become exposed to the germs. The pathogenic ones can be spread also by the favorite animals or the wildlife, as the deer, this walk by a vase field.

C. Dioxine: "The Darth Vader of chemical Products"
The dioxine is produced it diverted superfluous of chemical processes implying chlorine. According to the EPA, the vase display is the biggest distributor of earth of dioxine nationally. 10 Dioxine is a substance cancedroga¨ne known and was linked up to the breeding problems, the genetic damages, and endometriosis. The scientific proof suggests that there is not sure exposition equals to the dioxine. 11 As an expert of dioxine known called it, the dioxine is "the Darth Vader of chemical products," because you cannot see or can taste it, but the it is mortal. The source of contamination of dioxine in the vase is not known. It could be unloaded in the sewer system by the sources more unknown, more industrial or more residential. The dairy cows grazing on the earth of sludged can ingest dioxine and the chemical product will enter then humans through milk and meat.
7.5. What We do not Know Can Injure United States
The agency of Protection Ecologique federal considers that there is 70,000 synthetic one (naturally not arriving) the chemical products. Nevertheless, only 2% of these chemical products completely was tried. Indeed, even the poisonousness more basic trying results cannot be found in the public report for almost 75% of the the most widely used of these chemical products. The manners in which ones these chemical products affect human health and the manners in which ones they react mutually with the one the other in the environment (their "the effects synergistes") always are not known. Despite this, the industry has only need to retrieve offloads it 1% of these chemical products in the ways navigables and the sewers. Although the industries and the households relax thousands of chemical products, the World-wide vase uniformly only is tried for few heavy metals and of time in time tried for the dioxine and the toxic pesticides.

8. The chemical toxic product source
The vase contains heavy metals and the others polluting because the industry and the households use and relax far toxic chemical too many products. The sources of contaminates in the vase are a lot, depending on the ease of treatment of specific water and the community that it serves. The contamination sources include industrial relacchements, the small ones offload matters, the hospital relacchements, the domestic losses, leachates of the sites of disposals and Superfund, including offload them nuclear waste, and municipal water and the sewer systems as a that is unloaded in a sewer that takes to a plant of treatment of water could become potentially it left the vase that. If a worker to an industrial ease unloads accidentally toxic chemical products down below the sewer instead of liquidating it properly, these chemical products could finish by in the vase. Same manner, if a house gardener rinses a bottle containing toxic pesticides in the sink, these toxic pesticides could find their manner to the vase.
8.1. Industrial dangers
As discussed preceding, a lot of chemical products used by the industry properly were not tried and are not regulated or are retrieved. What's more, even to the opportunities more sure, the accidents arrive from the and the toxic chemical products can be relaxed in the waste stream. The world demands plants of treatment of worn waters to work with the big industries on to reduce and the interception of offloads them waste. This "the process of pretreatment" is demanded businesses that unload a big quantity of waste in the system of sewer or uses a big quantity of chemical products that could affect the operation of the system of sewer. Unfortunately, once the businesses relax heavy metals, or the other toxins, in the sewer system, there is not process to remove these chemical products of the vase. Besides, every industry in the country can unload 33 books of dangerous losses every month in the plants of treatment of worn waters, without the penalty or retrieving. 13
8.2. The small Dangers of Matters
A lot of small businesses are not regulated for their toxic relacchements. Are or they included in the processes of pretreatment. While the car garages, the offices of dentist, the photo contractors, dry cleaners, and the small others businesses cannot relax individually a big quantity of chemical toxic products, take as a body their contribution to the chemical products in the vase could be dangerous.
8.3. Hospital dangers
All hospitals are demanded to liquidate chemical products and toxic biohazards in a state approved the manner. Nevertheless, the accidents arrive: Of a hermometer broken mercury to the pathogenic additional humans is washed out the sewer, the hospitals can contaminate vase.
8.4. The contamination of Municipal Water and the Systems of Egout
A lot of cities and the cities have systems of water and sewer did with the pipes in advance and copper. The advance, the copper, and the other metals filters often in the stream of waste and contaminates vase. Vase contamination can arrive also if a city reservoir is polluted with the pesticides and the other chemical products for which the essay is not demanded.
8.5. Household dangers
Pesticides (including the flea shampooings), to very resistant cleaning agents and the hair dye of the products, the chemical toxic product contains products abound. Any of these chemical unloaded products down below the sewer could finish by is spread out over a field of farm or in a forest.

9. Vase regulation
The this is almost impossible knowledge the exact levels of toxic equipment in every fournede of vase because which is relaxed in the waste stream varies the day to the day. While the waste of drains is treated to the opportunities of worn waters for several days, not every fournede of vase is tried before it leaves the plant. The this is more because of the economical science than to the worries for the health protection, that the vase generators do not try the waste more frequently. For example, the waste only often is tried for the dioxine two times per year because of the test cost. A worker can reverse accidentally pesticides in a sewer of sink or storm, or someone illegally could unload other toxic chemical products down below the sewer, and does not import how the strict regulations are in the law books, the essay could lack these sudden increases in contaminating them. The regulations and the essay cannot guarantee security of vase until the toxic chemical products are removed usage of industrial household.

10. Vase consequences
"The temporary odors are a necessary disturbance in the farming practice". 14 odors of similar Vases to smoke and that the odor will disperse "in several days". Despite industry publicity, the studies showed to these vase odors are more just a boredom; they are a threat of public health. The harmful gasses, called organic amines, can develop chemical reactions that arrive in the vase. These gasses are relaxed when the pH of vase is above student 10, as when the files is added. The studies suggest that the vase odor causes the health problems in the humans as removed as 1600 feet of a study executed by an old regulating one of vase of EPA linked up odors of vase to "the harsh irritation to the muqueuses followed by the respiratory infections" in the living inhabitants close to a vase site. The eyes irritation, the throat and the skin do the infection of the pathogenic ones in the vase more probably. The study was directed following to the death of a man of New Hampshire suffering from distress respiratory nearby of a site of vase. 16 Inhabitants close to the vase sites were not the only victims of odor of vase. The symptoms associated with to poison organic amine arrives frequently among the workers of plant of treatment of waste and the drivers that transports vase.
10.1. The deaths associated with the vases
At least two deaths were associated with the vase display. In the month of October 1994, a boy of eleven years, Tony Behun named, went of the to take bicycle of earth close to his house in the Mills of Osceola, Pensylvanie. Inconsciemment, the boy took by a field cover in the vase of B of Class. It returned cover in the earth and the dirtiness. Two days later, it developed a painful throat, a headache, and an end on his left arm. Brenda Robertson, his mother, took it to the doctor, that prescribed the flu antibiotics. The next day, Tony had boredom breathing. It is dead after having is flown by the helicopter to a hospital in Pittsburgh. The final diagnosis was that Tony was dead of a bacterial infection. How his son contracted the infection remained a mystery to Brenda Robertson until five years later when she read of an investigation in the death of his son by the Department of Pensylvanie of Protection Ecologique. Without counsel Brenda, the state published a conclusive report that Tony is dead of a shot of bee and this Class B Vase was not spread out over the property that it went to take on.
Another vase related the death arrived to Greenland, New Hampshire. At the end of the month of October of 1995, the family of Marshall had their lives otherwise calm interrupted tragically. The vase was unloaded on a field in their rural neighborhood. This was just the beginning of the problems of the inhabitants. Night of the witches, Joanne Marshall hurried to the work house to take his small turn of girl-or-treating. When she arrived to the house and jumped of his car, she "was greeted by such a pong, it took his breath". 17 The Marshall and their neighbors began suffering from the airsick, vomit, the stomach crampes, the migraine headaches, the symptoms afflicts affectiant, slowed down reflex and respiratory problems.
10.2. Ecological Evaluation and some remedy:
Recycle vase of drains to the agricultural earth to win the advantage of the nutriments of essential plant and the organic question that it contains, would seem a reasonable and rational method to manage an equipment that would have otherwise need to liquidate by some other one non advantageous road. But the vase contains also contaminating them inorganic, organic and biological and so prudent, the direction is demanded to avoid the potential ecological problems. The problems are enumerated in the following Table. The big application of vase of drains can diminish the ground pH. This can be avoided, if the ground pH is increased by the application of files, or if the rates of application of vase are limited in certain respects.
The no of bacteria of different genera in the vase varies. Usually, an account coliforme total of 10 to 10 can be found by the gram of wt. dry, while the fecal coliformes generally represent 10 to 10 by the gram of dry wt. The pathogenic ones should be reduced to the levels that are not very probable to cause a threat to public health and the environment under the processes of conditions of specified usage significantly to reduce pathogenic, as the digestion, drying, heating and high pH or their equivalent one is the ordinarily the one used more.
For the abduction of OCs of the vase principally two approaches ar there ae" the chemical product of physico or microbiologique that implies or the high oxidation of temperature (the cremation) or dechlorination reducer (the pyrolysis in an atmosphere of hydrogenates). To attain to allow the risk level, the concentrations of presticide in the combined ground and the vase mixture must be less than 1.25 dry mg/kg wt.

The ecological risk of impact and takes advantage the evaluation to recycle vase of drains to the agricultural earth (B = the advantageous effect, L = the Low risk, P = the Possible risk, NA = Not applicable).

11. Vase regulation
The vase, by his same nature, is difficult to regulate. Depend on which chemical products is relaxed in the various minute of systems of sewer to the minute, the poisonousness of the vase of the state could vary everyday, meticulous-to-the minute. The vase regulations do not protect sufficiently public health and the environment.
11.1. The regulations problems:
aec To Have weak norms of pollution;
aec To Be anxious the account of the display of vase containing lives pathogenic;
aec To Discourage municipalities of is the health of precaution and public oriented by not allowing for them to do the stricter norms than the state; and
aec To Marginalize voices to citizens in the process as the vase industry has the biggest access to declare regulating than the average citizen.

12. The vase solution
If spreading vase in our communities is dangerous, where should it go? What be us supposed to do with this waste? The true question is, how can we eliminate the displays of toxic pollutants on our earth and how we can eliminate these contaminating of our plant of treatment of worn waters for that the human waste become a truly useful and sure commodity? Because the vase contains toxic chemical products and the others polluting, the better solution to our vase problem reduces these contaminating to their source. By reducing in a manner spectacular the usage and the disposal of industrial and household products toxic chemical can cut us strong the chemical levels in the vase. Until the objective in the long term to eliminate the usage and the chemical toxic product disposal are attained, the state has:

1. Forbid the vase usage that contains industrial disposals.
2. Demand the level more strict of reduction of pathogenic one.
3. Elargir and strengthen essay of vase and toxic limits.
4. Allow the to the municipalities to promulgate orders that are more severe than the regulations of the state by the city meeting or a process of vote city wide.
5. Support in the long term of pH and to the interception of metal of sites of vase.

What's more protections in all the state, the municipalities should apply also their own protections by the strong orders checking vase. The this is, after all, the local communities that it more threatened by the vase display.
13. The vase disposal
The vase disposal is a world-wide problem and a big variety of roads of disposal were adopted as directed by the local conditions. The last abode of the vase must be or on the earth, in the air or in water. The vase disposal to the air big employs the high cremation of temperature or the pyrolysis. Although, this reduction is sufficient for "to stabilize" the vase, a big volume remains for the disposal. The disposal of vase of drains to the ocean in forbade now because of its ecological perceived effects. The major methods of disposal of vase salaried by the plants of treatment of water of waste are lagooning of alienation or sale, used for the municipal gardens, used for the culture of immediate lawn, lands the application. To remain it of the vase or is stocked or lands filled.

The disposal and the vase application should imply the to follow

1. The application must contain a summary of the types of harvests to be grown on the proposed site, the method of application of vase, and a plan of foreseen display. The application must include also a ground a representative nutritious analysis for the site.
2. The vase must furnish "the advantage of agronomic" to the growing harvests on this ground -- meaning that the generator must show that the site has a need for the nutriments provided with by the vase. The farms using vase is demanded to have a direction nutritious authorized specialist develops a farm an entire project of nutritious direction. This project is the basis for the above mentioned determination that the additional nutriments are necessary on the farm. 19
3. The application must show that "state water will be protected". In the practice, the regulating ones of the state suppose that state waters will be protected provided that the certain backs and the display conditions are provided with in the application.

4. To this end, the vase cannot be spread when the ground is frozen, the snow covered, and water noted. The vase cannot be spread out over the earth that favors the water growth plant stretch as the earths maredcageuses, the marshes and of others.
5. The ground of a site of proposed vase must have a cork of ground of six thumbs and a depth minimum to the foundation of 10 thumbs for the constant harvests (as the hay) and 20 thumbs for the row harvests (as the corn).
6. For the vase of B of Class, the display cannot arrive in 25 feet of ways navigables on the spot, including the ravins, the ravins, and swales. The vase sites could not be localized in 75 feet of a river, in the constant stream, or in the big pond.
7. The application must include a declaration if or not the site is localized on or next to a natural protected resource, a sensitive sector, and/or a direct turn to waters.
8. The generator must show that the activity of display of vase will meet the circulation norms for the site. This norm is supposed to be met if the activity of display of vase will have for result 16 or less than vehicle stumbles a day. 20
9. The application must include a project of check of odor site specific to prevent the boredom odors to the neighboring property. It supposes that the odor, the air quality, and the boredom norms will be met at the site if the site is 300 feet of the buildings occupied, if there is a site a project of check of specific odor. 21
10. The application must prove that the vase is "without risks". To prove this, the application must include a level analysis in heavy metals in the vase. If the generator vase contains concentrations in heavy metals above to sort concentrations then the application must include a sampling and interception plans just like shows that the ground concentration in metal, heavy and maximum will not be surpassed.

11. The application must include also an analysis of the level of dioxine in the vase. If a generator vase contains 27 parties by the trillion of dioxine, then the application must include a declaration signed by the generator, the important owner, and the operator recognizing the dioxine in the vase to be spread.
The declaration must include also an agreement to the following conditions:
? The site will be tried for the dioxine in 3 months of the last display of vase.
? If the ground on the site contains 27 parties by the trillion of dioxine, then the desired cattle for the human consumption could not be pastured on the site, the harvests for the human consumption could not be grown on the site, and the action to the site must record these information.

12. The application must include also a project of sampling: how many times and in which manner the vase will be tried for the heavy metals and the other toxins. 22
13. The vase will be spread to at least 15 thumbs above the surfaces of underground water. The food crops growing on the site with the harvested parties that touch the ground will not be harvested for 14 months after the last display of vase.
14. If the vase remains on the earth for four months or more more before being more incorporated in the ground, the food crops that growing to the under ground cannot be harvested for at least 20 months after the last display of vase.
15. The food crops, nourishes harvests, and the fiber crops growing on the site but has not on the part harvested that could touch the vase cannot be harvested for at least 30 days after the last display of vase.
16. The animals domesticate are not allowed grazing on the earth for at least 30 days after the last display of vase.
17. The growing lawn on the site cannot be harvested for a year after the last vase
Etalage.

18. The application must contain the site cards, including: a card of topographical; a site sketch; a tax card; the grounds do the card of (of American Department of Farming); the sand and the card of aquifer of gravel; and a card of zone of flood.
19. The site sketch should include all the backs and the plugs set up that will be incorporated, just like the location of on the spot and results roads, well, and the buildings. The cards of topographical are used to determine slopes to the site. The grounds, the aquifer of sand and gravel, and the cards of zone of flood is used to determine if the site is suitable, in a regulating direction, for the activities of display of vase. 23

14. Conclusion and Recommendation
14.1. Recommendation of political one

? Forbid vase that contains industrial disposals of is the applied earth. The better manner to guarantee than our rural earth is protected from contamination industrial is to forbid the vase usage that contains these toxins.

? Demand the vase of broadcasting of earth to undergo the method of reduction of pathogenic most available strictest one. The vase with the viruses, the bacteria, and the parasites above the bottom levels should not be the applied earth.
? Elargir and strengthen parameters of essay of vase. The vase needs to be tried more frequently for more of contaminate. In the order better to protect public health and the environment, the levels of admissible pollutant should be directed not only by the toxicology but also by the levels of natural bottom also.
? Allow the to the municipalities to promulgate orders that are more severe than the state by a city meeting or the vote city wide. The people that it more affected by the vase sites are local inhabitants. The it is important that these inhabitants have a voice when it is a decision matter that affect their community.
? Support in the long term of sites of vase. The vase generators should be responsible to try the pH of all sites of application of vase, so active or closed, and cover the costs of files (or the other amendments) to maintain pH of sure ground. All big activities of vase of volume should be recorded on the actions for that the potential buyers futures are conscious past usage of the property.


15.2. The recommendation for the municipalities
aec The Vase is an especially important problem for the municipalities to oversee: the this is local inhabitants that has the most lost one of the threat of vase.
aec In the municipalities that welcome an ease of treatment of worn waters, the local inhabitants, the city officers, and the ease directors can work together to execute the recommendation au-dessus in all the state at the local level.
aec All cities have the authority to forbid the vase usage, or vase equipment (as the compost) on the municipal property.
aec The Municipalities can pass also strict orders checking application of vase. Although the state anticipates the local check on the framework norms strict, there are several manners that the cities can discourage display of vase.

15.3. Which citizen of worry can do?
The citizens can protect themselves and their community of the dangers of vase by is engaged proactivement in the vase reformation. Depend on the community needs, the citizens can reform rules of vase by the city officers charming, local healths and in all the public states and the ecological groups.
