Water pollution is the contamination of water bodies, usually as a result of human activities. Water bodies include for example lakes, rivers, oceans, aquifers and groundwater. Water pollution results when contaminants are introduced into the natural environment. For example, releasing inadequately treated wastewater into natural water bodies can lead to degradation of aquatic ecosystems. In turn, this can lead to public health problems for people living downstream. They may use the same polluted river water for drinking or bathing or irrigation. Water pollution is the leading worldwide cause of death and disease, e.g. due to water-borne diseases.[1][2] Water pollution can be grouped into surface water pollution. Marine pollution and nutrient pollution are subsets of water pollution. Sources of water pollution are either point sources and non-point sources. Point sources have one identifiable cause of the pollution, such as a storm drain, wastewater treatment plant or stream. Non-point sources ...

It is an enormous problem in many parts of the world and it causes many thousands of deaths daily. Groundwater too can become polluted and this can create a whole set of new problems such as the difficulty in predicting the downstream effects.. Rapidly developing countries like China and India have particularly severe problems with water pollution with hundreds of millions of people in those countries lacking safe drinking water and suffering poor sanitation. Once great rivers like the Ganges in India are now so polluted that they present high disease risk to those who depend on them. The developed world also has serious water pollution problems with many bays, lakes and river systems polluted worldwide. Pollution can arise from many man-made sources and natural events like volcanoes can ...
Water pollution is a serious problem worldwide, whether in rivers and lakes or massive oceans. After the famous Cuyahoga River fire of 1969, environmental regulations were put into place in the U.S. which have helped curb the amount of pollutants we put into our water and reversed some, but not all, of the problems stemming from water pollution. Unfortunately, even with strict policies and treatment facilities, water pollution is still a big issue. Tracking polluters is difficult as these infractions often happen silently and in remote areas, and sometimes unintentionally.. Two pollutants that are difficult to tame are nitrogen and phosphorus. Found in fertilizers and pet waste, these two chemical elements run off into bodies of water during rain events. Both nitrogen and phosphorus are a part of a healthy aquatic ecosystem, supporting the growth of underwater plants, which produce oxygen, and habitat that support aquatic organisms. Nitrogen and phosphorus also support the growth of algae, a ...

Water is a necessity for life, and clean water is usually a sign of a healthy environment. Human activities can have adverse effects on water quality. For example, the use of fertilizers in agriculture can lead to increased nutrient levels in nearby waters and cause increased eutrophication. Thus, monitoring water quality is an essential part of taking care of the environment.. Water transparency is one commonly used indicator of water quality. It is mentioned as a supporting factor for the biological elements in the Water Framework Directive (WFD) (Solimini et al. 2006) and as one of the physicochemical quality elements for the ecological classification of coastal waters in the Marine Strategy Framework Directive (MSD) (Piha and Zampoukas 2011). High transparency values indicate clear water, whereas low transparency values indicate turbid or highly absorbing water, which usually means poor water quality. Water transparency defines how deep sun light will penetrate and hence the depth at which ...
Efforts to improve the quality of rivers, streams, lakes, groundwater and coastal waters in the UK have been going on for many years, mostly driven by the requirements of EU Directives (Water Framework Directive, the Drinking Water Directive and the Bathing Water Directive). However, with Britains recent decision to leave the European Union leading to increased discussions about the future of water policy in the UK, this symposium comes at a very timely moment.

Water pollution comes from businesses, farms, homes, industries, and other sources. It includes sewage, industrial chemicals, agricultural chemicals, and livestock wastes. Water pollution occurs when people put so much waste into a water system that its natural cleansing processes cannot function properly. Some waste, such as oil, industrial acids, or farm pesticides, poisons aquatic plants and animals. Other waste, such as phosphate detergents, chemical fertilizers, and animal manure, pollutes by supplying excess nutrients for aquatic life. This pollution process is called eutrophication. It begins when large amounts of nutrients flow into a water system. These nutrients stimulate excessive growth of algae. As more algae grow, more also die. Bacteria in the water use up large amounts of oxygen consuming the excess dead algae. The oxygen level of the water then drops, causing many aquatic plants and animals to die ...
Definition Of Water Pollution Environmental Sciences Essay Water pollution is the presence of any substances in water which can be harmful for plants and animals that live in water or people who use it. In other word it is the change in the chemical or physical properties of the water and this change can lead to cause damage and health hazards to animals and plants that live inside it or organisms that use it. (1) Importance of the Nile River for Egypt The Nile River is the primary water resource in Egypt, where it represents more than 95% of the total water resources in Egypt and it is the lifeline for Egypt and there are many reasons for its importance which are: Egyptians depends on it to acquire fresh water to use it for various purposes such as drinking, cooking, cleaning and other household uses. Use it for agriculture where fertile land formed around the Nile River and they irrigated by Nile River. The Nile River is an important source of fish. It is used in water transportation because ...
Using the most comprehensive data file ever compiled on air pollution, water pollution, environmental regulations, and infant mortality from a developing country, the paper examines the effectiveness of Indias environmental regulations. The air pollution regulations were effective at reducing ambient concentrations of particulate matter, sulfur dioxide, and nitrogen dioxide. The most successful air pollution regulation is associated with a modest and statistically insignificant decline in infant mortality. However, the water pollution regulations had no observable effect. Overall, these results contradict the conventional wisdom that environmental quality is a deterministic function of income and underscore the role of institutions and politics. ...
This staggering extent of water pollution is very serious because water can and does transport pollution from one location to another. There is growing industrialization all over the world and the worlds population is also growing rapidly. There are now millions of people who live near rivers, along coastlines and various waterways. Obviously, these are the sources of heavy water pollution. In addition, industries also have been fairly irresponsible in their attitudes, till recently dumping all chemical wastes into nearby waters, with not many of them worrying about the consequences of doing so ...
Water pollution is a matter of great concern in lentic and lotic ecosystems. Generally water pollutants like heavy metals, organic compounds, etc. generate from industries and domestic activities. All of these pose serious threat to the fish population in freshwater as well as marine water bodies. An impact caused by water pollutants especially genotoxins depend not only upon its concentration, but also on the duration (acute and chronic exposure) and showed individual and/or combination of pollutants or genotoxins. Genotoxicity of fish with special reference to micronucleus induction in the erythrocytes of fish is an easy screening of water pollution. The present review deals with past and present research works of major water pollutants discharge and their impact on several fish species from available literatures.

The use of biological effects tools offer enormous potential to meet the challenges outlined by the European Union Marine Strategy Framework Directive (MSFD) whereby Member States are required to develop a robust set of tools for defining 11 qualitative descriptors of Good Environmental Status (GES), such as demonstrating that Concentrations of contaminants are at levels not giving rise to pollution effects (GES Descriptor 8). This paper discusses the combined approach of monitoring chemical contaminant levels, along side biological effect measurements relating to the effect of pollutants, for undertaking assessments of GES across European marine regions. We outline the minimum standards that biological effects tools should meet if they are to be used for defining GES in relation to Descriptor 8 and describe the current international initiatives underway to develop assessment criteria for these biological effects techniques.
Phase 1 -- Areas that are not designated as either Phase 2 or Phase 3.. Phase 2 -- Areas that have from 50% to 90% of the Maximum Contaminant Level for a contaminant (5 to 9 ppm of nitrate-nitrogen), or are vulnerable to groundwater contamination, or have vadose zone contamination that indicates a potential for groundwater contamination, or are in the recharge areas for public supply wells, or are areas with similar soil and land use conditions as an existing Phase 2 or 3 area. Phase 2 areas must be a minimum of 10 square miles in size.. Phase 3 -- Areas with greater than 90% of the Maximum Contaminant Level for a contaminant (9 ppm of nitrate-nitrogen), or are vulnerable to groundwater contamination, or have vadose zone contamination that indicates a potential for groundwater contamination, or are in the recharge areas for public supply wells, or are areas with similar soil and land use conditions as an existing Phase 3 area. Phase 3 areas must be a minimum of 10 square miles in size. ...

AU - Allan, R.. N1 - Conference code: 13. PY - 2016/9/16. Y1 - 2016/9/16. N2 - Environmental pollution and risks to human health can result from diffuse sources of pollution originating from decentralised wastewater treatment systems (DWTS). In particular phosphorus pollution can lead to eutrophication and the downgrading of the quality of water bodies, for example, under the Water Framework Directive (WFD) in the EU, and pathogen pollution can result in increased risks of human exposure to pathogens and impacts on industries such as shellfish growing and tourism. The study reported in this paper reviews the effectiveness of various DWTS in removing phosphorus and pathogens from onsite systems. It was found that DWTS are typically not designed to specifically treat these pollutants and the most ...
Downloadable! [paper in French] In Brittany, water policy give little results compared to the money involved. Compared to northern European countries the French government dont enforce the economic principles of the water framework directive (WFD). WFD defines the environmental target as an economic optimum which maximizes the collective value or minimizes social costs. Further, WFD says that water policy has to enforce cost recovery and polluter-pay principle (PPP). WFD economic principles are compared to the French policy for reducing animal pollution which is based on hypertrophic set of regulation and reject of PPP. This explains why producers dont have incentives to reduce pollution by using least cost solutions like manure spreading. We suggest to limit the states paper to defining and enforcing standards via the PPP and to suppress the obstacles to manure spreading.
Water governance worldwide is going through a shift towards more holistic and participatory approaches. In Europe, the EU Water Framework Directive (WFD) adopted in 2000, aims at protecting surface water and groundwater. The WFD emphasizes the importance of stakeholder participation in planning and implementation of the directive, and in order to reach environmental objectives. However, the empirical findings are insufficient regarding how stakeholder participation can lead to improved decisions and implemented plans. In Sweden, a major water quality problem is eutrophication caused to a large extend by diffuse nutrient leakage from agriculture. Therefore, it is important to involve farmers in water management, since their participation can lead the commitment of mitigation measures for reduced nutrient leakage. The overall aim of this study is to contribute the knowledge and understanding of active stakeholder participation in water management, in particular how it can lead to implementation of ...

Application of anaerobic swine (Sus scrofa domesticus) lagoon liquid onto cropland by irrigation is a common method of waste disposal and treatment. Currently, the application rate of swine lagoon liquid is based on the N concentration of the lagoon liqu id and the N required by the receiver crop to obtain a realistic yield. In North Carolina, only 50% of the total N in the swine lagoon liquid applied by irrigation is considered available for plant use during the first year after application. Uncertaint y exists as to whether this coefficient accurately predicts the amount of plant-available N. Therefore, research was conducted in the Coastal Plain of North Carolina to determine the efficiency of N uptake by corn (Zea mays L.) and soybean (Glycine max M errill) receiving swine lagoon liquid through irrigation. The line-source sprinkler irrigation method was used to provide a continuous variable N rate, ranging from 0 to 290 kg N/ha, across the field during 1999 and 2000. Ammonia volatilization ...

Loch Leven is in unfavourable condition. Attaining good water quality is critical to sustaining its many designated conservation features (SSSI, SPA, Ramsar site and NNR) in order to meet European Union Habitats and Water Framework Directive targets. High inputs of nutrients to the loch from its catchment (especially of phosphorus) have been identified as a key driver of these water quality problems. Long-term monitoring of the water quality within Loch Leven has been undertaken by the Natural Environment Research Council (NERC) since the late 1960s. The overall objective of this project was to assess the current phosphorus and nitrogen inputs to Loch Leven and provide information on their likely sources.. ...
Fewer than 5% of leading dairy producers have a thorough understanding of the Water Framework Directive unveiled in 2000, despite it containing obligations for all producers to help improve water quality.
Article Outline Acknowledgements References The EU Water Framework Directive (WFD) by the European Commission is the major concept for achieving sustainable management of water in EU Member States. Next to treatment of coastal waters, it requires that all inland waters within defined river basins must reach at least good status by 2015. This also requires a constantly improved understanding of physical, chemical and biological processes of pollutants for the assessment of current and future quality of surface- and groundwater bodies. As a driving force for concepts such as the WFD, the EU project AquaTerra aims at a better understanding of pollutants in the river-sediment-soil-groundwater systems as a whole. This involves quantification of key pollutants and understanding of their turnover. The work also leads to the development of new numerical models, which are needed to predict adverse trends in soil functioning, water quantity and quality. Scales range from water-solid interactions to ...

by admin , Jul 21, 2017 , Asbestos, Environment Agency, Environmental Health, Water Framework Directive. As you will be aware we have had major concerns about our ageing and deteriorating asbestos cement drinking water pipes for some time now. Due to the age of previous significant development in Cranleigh in the 60s, we suspected that they may contain crocidolite (blue asbestos), in addition to chrysotile (white asbestos). Although Thames Water assured us that the pipes were constructed from white asbestos, our own research did not reflect this, and we have been pushing for testing to be carried out.. Over the past two weeks we were successful in getting Thames Water to send a section of drinking water pipe, being replaced in the Hitherwood area, for independent testing to confirm the presence of blue asbestos (crocidolite). This has now been confirmed.. The presence of crocidolite (blue asbestos) is not the result we were hoping for, but it is in line with the guidance given on the Health and ...
The general objective of the REBECCA project1 is to provide relevant scientific support for the implementation of the Water Framework Directive (WFD). The two specific aims of the project are, firstly, to establish links between ecological status of surface waters and physico-chemical quality elements and pressures from different sources, and, secondly, to develop and validate tools that member states can use in the process of classification, in the design of their monitoring programs, and in the design of measures in accordance with the requirements of the WFD. Historically, there has been great success in maintaining and improving the quality of surface waters by developing an understanding of the links between anthropogenic pressures (e.g. water abstraction, agriculture, and effluent discharges) and the chemical status of waters, although there remain many challenges in reliably designing and implementing the necessary programs of measures. Our present understanding of the link between ...

In the bleak future that the film Soylent Green envisions, water is a priceless commodity. All drinking water must be boiled before it can be imbibed and is rather difficult to find in the first place. Further, everyday luxuries that many people take for granted, such as washing ones hands or bathing, simply cannot be done because there is no water to spare. In the same vein, or should I say pipe, indoor plumbing in the film is a creature comfort reserved only for the wealthy and well to-do. In order to ensure that our current water levels and supplies are not drastically depleted, as they are in the future Soylent Green depicts, we must prevent water pollution and discover methods that promote aquatic sustainability in our everyday lives. ...

A process for removing metal ions such as mercury, copper, cadmium, zinc, lead, nickel or silver from polluted waters includes causing the metal polluted water and a sulfur-containing precipitating agent to diffuse through peat whereby a water insoluble sulfide of the metal is formed and is adsorbed on the peat and the metal free water is recovered. The process also relates to recovering the metal either as metal oxide or as metal in the case of silver, copper and mercury by burning the metal sulfide-containing peat.
The City of Baltimore, Maryland, and parts of five surrounding counties obtain their water from Loch Raven and Liberty Reservoirs. A third reservoir, Prettyboy, is used to resupply Loch Raven Reservoir. Management of the watershed conditions for each reservoir is a shared responsibility by agreement among City, County, and State jurisdictions. The most recent (2005) Baltimore Reservoir Watershed Management Agreement (RWMA) called for continued and improved water-quality monitoring in the reservoirs and selected watershed tributaries. The U.S. Geological Survey (USGS) conducted a retrospective review of the effectiveness of monitoring data obtained and analyzed by the RWMA jurisdictions from 1981 through 2007 to help identify possible improvements in the monitoring program to address RWMA water-quality concerns. Long-term water-quality concerns include eutrophication and sedimentation in the reservoirs, and elevated concentrations of (a) nutrients (nitrogen and phosphorus) being transported from the
Approximately 95 percent of this countrys rural residents use groundwater to supply their drinking water and farmstead needs. Wells are designed to provide clean water. If improperly constructed or poorly maintained, they can allow bacteria, pesticides, fertilizer or oil products to contaminate groundwater. These contaminants can put family and livestock health at risk.. Cases exist that document well contamination from farmstead activities near drinking-water wells. The condition of your well and its proximity to contamination sources determine the risk it poses to the water you drink. For example, a cracked well casing allows bacteria, nitrates, oil and pesticides to enter the well more easily. Spilling pesticides being mixed and loaded near the well could result in the contamination of your familys drinking-water supply. Feedlots, animal lots, septic systems, fertilizer applications and waste storage areas could release large amounts of nitrate, contaminating your well.. Preventing ...
erosion now probably rivals the effects of geologic forces. Worldwide, erosion from croplands, forests, grazing lands, and construction sites is estimated to add some 75 billion tons of sediment each year to rivers and lakes. This sediment smothers gravel beds in which fish lay their eggs. It fills lakes and reservoirs, obstructs shipping channels, clogs hydroelectric turbines, and makes drinking water purification more costly. The most serious water pollutant in terms of human health worldwide is pathogenic (disease-causing) organisms. Among the most deadly waterborne diseases are cholera, dysentery, polio, infectious hepatitis, and schistosomiasis. Together, these diseases probably cause at least two billion new cases of disease each year and kill somewhere between six and eight million people. The largest source of infectious agents in water is untreated or insufficiently treated human and animal waste. The United Nations estimates that about half the worlds population has inadequate ...
The workshop had the title "Potential of Genomics Technology for Marine Monitoring and the Marine Strategy Framework Directive (MSFD)", and was arranged in collaboration with MG4U [6]. The meeting was organized by Matthias Obst (University of Gothenburg, Sweden) and chaired by John Benzie (University College Cork, Ireland), and assembled 31 genomics scientists as well as representatives of marine policy bodies. The program featured short scientific talks, breakout sessions and panel discussions [35].. Introduction: The Marine Strategy Framework Directive (MSFD) is a legal framework that demands a repertoire of knowledge from the European member states centered around the descriptors of good environmental status (GES). The descriptors, together with associated criteria and indicators will be used to decide on the status of marine ecosystems, and how GES can be achieved and maintained in the future. On this basis, the member states have to provide the initial assessment (of current status) ...
Water pollution degrades surface waters making them unsafe for drinking, fishing, swimming, and other activities.. Storm water is water from rain or melting snow. It flows from rooftops, over paved streets, sidewalks and parking lots, across bare soil and lawns and into storm drains and streams. As it flows, runoff collects and transports litter, soil, pet waste, road salt and sand, pesticides, fertilizer, oil and grease, soaps and detergents, and a host of other pollutants. Storm water drains directly into nearby creeks, streams and rivers without receiving treatment at a wastewater treatment plant.. Storm water runoff is major contributor to water pollution nationwide and one of the great challenges of pollution control.. Untreated runoff degrades waterways. It affects water quality and the environment and reduces how much we can use streams, rivers and lakes for fishing, swimming and as a source for drinking water. Litter and sediment can also reduce storm drain and stream capacity, which ...

Municipal SewageMunicipal sewage is a major source of pollution. About 2 million wet tonnes of human excreta are annually produced in the urban sector of which around 50% go into water bodies to pollute them. National Conservation Strategy (NCS) states that almost 40% of deaths are related to water borne diseases. Domestic wastewater collects on the streets and in low-lying areas. The situation is further aggravated by the addition of untreated wastes from small-scale industries. In Pakistan, drinking water supply lines and open sewage drains in the streets are laid side by side. As a result, water is frequently contaminated when pipes erode. Most main sewers are between 30-50ft below ground level and are made of 10ft cement sections linked without proper safety seals. Poor connections combined with deteriorating low quality sewer pipes cause a lot of leakage. This outflow from sewer mixes with the water table and the contamination is carried to deeper levels. Hence the ground water which is ...
Dont worry, this picture is several years old and we havent seen this kind of algae pile up on our local beaches in SW Florida in several years. However it has happened several times within the last 15 years and it creates lasting impressions of the health of our lakes, rivers and estuaries. Scientists, the Environmental protection Agency and other groups have been studying what causes this problem but the culprit seems to be nitrogen, phosphorous, and human and animal waste being carried into our waterways by storm water runoff and excessive fertilizers being used too close to rivers and streams. The excessive loading of these pollutants causes the massive algae blooms and green scum that covers the water. I have seen thousands of dead fish lying on the shores of our rivers and beaches because of the excessive amounts of nutrients carried into our waterways. Florida is a heavily populated state with yards, farms and mining operations all playing a part in the problem. There are many efforts ...
Contaminated water causes many more disease than we are aware. According to a United Nations report, "more people die from contaminated and polluted water than from all forms of violence, including wars." This is surprising information indeed ...
While information on the effects of long term low-dosage exposure of ECs and PPCPs on humans is still being collected, the effects on aquatic organisms and ecosystems has been observed, studied, and documented. A significant portion of these studies have focused on hormone disruption in aquatic organisms caused by exposure to trace organic compounds. An increase in the discovery of intersex organisms, i.e. fish having developed male and female reproductive organisms, has led scientists to question the environmental impact of low doses of hormones. The table below, taken from the Nov. 2008 AWWA Journal article "Emerging Compounds: A Concern for Water and Wastewater Utilities," highlights some of the potential ecological effects of trace compounds found in wastewater effluent. ...
Point source pollution . These are largely organic materials as wall as sewage materials like human excreta, dung and urine of animals, some dissolved proteins, carbohydrates, fats and a variety of inorganic wastes such as nitrites, nitrates, phosphates, chlorides, sulphates and mineral elements like sodium, potassium etc That can be oxidized by micro-organisms to carbon dioxide and water. When the amount of sewage discharged is relatively small, the river will not become badly polluted. So the biological degradation will soon remove most of the wastes but if not so it makes the water pollute very soon 1. Sewage and other oxygen demanding wastes: . If a question like this--Why sewage and other oxygen demanding wastes are classified as water pollutants? . Answer will be like this--- Because of the following reasons: A. Their degradation leads to oxygen depletion which affects or even kills fish and other aquatic life. B. They produce foul odor and undesired colors. C. They may lead to scam and ...
Although the biochemical reactions undergoing in the natural systems as outlined in the previous section are mainly governed by two types of suspended and biofilm bacteria, the design equations formulated in the past emphasized the role of the suspended bacteria only. An early study by Reynolds et al. [17] recognized the potential of biofilm bacteria growing on the surface of baffles submersed in the pond water in organic stabilization. Some previous researches on self-purification in shallow streams and rivers have shown biofilm bacteria growing in open-channel beds to be effective in biodegrading organic carbon compounds [18-22]. Recent studies on attach-growth WSPs found the biofilm bacteria growing on attached-growth media installed in the pond water to be effective in waste stabilisation [23-25]. From their laboratory experiments, Kilani and Ogunrombi [26] reported that WSP installed with baffles yielded better treatment performance than those without baffles; although they attributed the ...

Any person who discharges, transports, or handles storm water from an animal feeding facility, as defined in section 903.01 of the Revised Code, or pollutants from a concentrated animal feeding operation, as both terms are defined in that section, is not required to obtain a permit under division (J)(1) of this section for the installation or modification of a disposal system involving pollutants or storm water or any parts of such a system on ...
In Minnesota, DENCO II LLC, an ethanol plant in Morris, has agreed to pay a fine and take steps to prevent discharges of polluted stormwater and wastewater into nearby surface waters, including wetlands that drain to the Pomme de Terre River. The company also agreed to correct several other problems following an investigation by the Minnesota Pollution Control Agency (MPCA).. The companys discharge permit allows the plant to release stormwater and wastewater containing limited concentrations of various pollutants to nearby surface waters. The plant discharges directly to an 8.1-acre wetland complex that flows to the Green River and then the Pomme de Terre River roughly a mile from the facility.. An MPCA investigation into records and practices revealed violations of the permit that included failure to adequately monitor, report, and correct discharges containing excessive amounts of organic material, total suspended solids, disinfectants used at the plant referred to as "residual oxidants," as ...
The study is to develop a genetic-based method that can complement the current surveillance methods for Asian carps (AC), an invasive fish species of many water bodies in the U.S. We propose to determine the relative abundance of AC through the quantification of the microbial populations unique to the AC gut microbiota in a manner similar to microbial source tracking. Microbial source tracking is based on the concept that microbes from a polluted site can be traced to an animal, and thus indicating the origin of fecal contamination. This approach has been successfully applied to identify the sources (e.g. human, cow, swine, and water fowl) of fecal contamination in rivers, lakes, and drinking water distribution systems. Similarly, key microbial populations can be identified in the fecal matter of AC, which can then be used for the development of a genetic-based method to detect the presence of AC in water bodies. To do so, differences in the gut flora between indigenous planktivorous gizzard ...

Water Pollution. The sheer volume of manure that factory farms generate transform it from a benign soil enhancer into a destructive water polluter. Agricultural runoff is the single largest source of water pollution in the nations rivers and streams, according to the EPA. An estimated 195 million Americans fall ill each year from waterborne parasites, viruses or bacteria, including those stemming from human and animal waste, according to a study published in 2008 in the scientific journal Reviews of Environmental Contamination and Toxicology.. Global warming, believed to increase the frequency and severity of extreme weather events such as flooding, is only going to exacerbate the problem for communities along the coast as well as along rivers and streams. Hurricane Floyd, in 1999, resulted in massive amounts of chicken waste washed into the Chesapeake Bay from burst and flooded lagoons, threatening fish and wildlife habitat. Phosphorus concentrations in Pocomoke Sound (downstream from the ...

Representatives from Aerojet and Mammoet did not respond to requests for comment. Fred Plotke, owner of Time Realty, who paid $100,000 to settle with the EPA, called the situation a "living nightmare." Plotke said his 7200-square-foot property on Rush Street, which has housed a small aircraft parts company and an auto repair business, probably was the source of some pollution over the years, but he didnt feel the amount he was being asked for was fair. He said the EPA originally asked him for $1 million in cleanup costs associated with the property. He estimated that over the past decade, hes racked up about $200,000 in legal fees fighting the EPA over a piece of property that cost him $140,000 to buy in the early 1990s. "The way they handle these cases is truly outrageous," he said. "There should be some kind of a formula for small companies." Plotke called the formula for assigning blame "terribly flawed," but said he settled just so he could get on with his life. "I think the whole case was ...
