Water Pollutants, Chemical
Nitrogen oxide (NO2). A highly poisonous gas. Exposure produces inflammation of lungs that may only cause slight pain or pass unnoticed, but resulting edema several days later may cause death. (From Merck, 11th ed) It is a major atmospheric pollutant that is able to absorb UV light that does not reach the earth's surface.
The unstable triatomic form of oxygen, O3. It is a powerful oxidant that is produced for various chemical and industrial uses. Its production is also catalyzed in the ATMOSPHERE by ULTRAVIOLET RAY irradiation of oxygen or other ozone precursors such as VOLATILE ORGANIC COMPOUNDS and NITROGEN OXIDES. About 90% of the ozone in the atmosphere exists in the stratosphere (STRATOSPHERIC OZONE).
Any of several processes in which undesirable impurities in water are removed or neutralized; for example, chlorination, filtration, primary treatment, ion exchange, and distillation. It includes treatment of WASTE WATER to provide potable and hygienic water in a controlled or closed environment as well as provision of public drinking water supplies.

Effects of dispersed recreational activities on the microbiological quality of forest surface water. (1/712)The microbiological quality of forest surface waters in the Greenwater River watershed was examined to investigate the influence of heavy motorized camping in an area with no sanitary facilities. Indicator densities increased during weekend human-use periods when compared to weekdays. Increases in indicator densities were also noted downstream from heavily used camping areas when compared to upstream sites. Seasonal, weekly, and diurnal fluctuations in indicator densities were observed. This study suggests that potential health hazards exist in this watershed during periods of human use. (+info)
Water pollution and human health in China. (2/712)China's extraordinary economic growth, industrialization, and urbanization, coupled with inadequate investment in basic water supply and treatment infrastructure, have resulted in widespread water pollution. In China today approximately 700 million people--over half the population--consume drinking water contaminated with levels of animal and human excreta that exceed maximum permissible levels by as much as 86% in rural areas and 28% in urban areas. By the year 2000, the volume of wastewater produced could double from 1990 levels to almost 78 billion tons. These are alarming trends with potentially serious consequences for human health. This paper reviews and analyzes recent Chinese reports on public health and water resources to shed light on what recent trends imply for China's environmental risk transition. This paper has two major conclusions. First, the critical deficits in basic water supply and sewage treatment infrastructure have increased the risk of exposure to infectious and parasitic disease and to a growing volume of industrial chemicals, heavy metals, and algal toxins. Second, the lack of coordination between environmental and public health objectives, a complex and fragmented system to manage water resources, and the general treatment of water as a common property resource mean that the water quality and quantity problems observed as well as the health threats identified are likely to become more acute.

Tetrachloroethylene-contaminated drinking water in Massachusetts and the risk of colon-rectum, lung, and other cancers. (3/712)We conducted a population-based case-control study to evaluate the relationship between cancer of the colon-rectum (n = 326), lung (n = 252), brain (n = 37), and pancreas (n = 37), and exposure to tetrachloroethylene (PCE) from public drinking water. Subjects were exposed to PCE when it leached from the vinyl lining of drinking-water distribution pipes. Relative delivered dose of PCE was estimated using a model that took into account residential location, years of residence, water flow, and pipe characteristics. Adjusted odds ratios (ORs) for lung cancer were moderately elevated among subjects whose exposure level was above the 90th percentile whether or not a latent period was assumed [ORs and 95% confidence intervals (CIs), 3.7 (1.0-11.7), 3.3 (0.6-13.4), 6.2 (1.1-31.6), and 19.3 (2.5-141.7) for 0, 5, 7, and 9 years of latency, respectively]. The adjusted ORs for colon-rectum cancer were modestly elevated among ever-exposed subjects as more years of latency were assumed [OR and CI, 1.7 (0.8-3.8) and 2.0 (0.6-5.8) for 11 and 13 years of latency, respectively]. These elevated ORs stemmed mainly from associations with rectal cancer. Adjusted ORs for rectal cancer among ever-exposed subjects were more elevated [OR and CI, 2.6 (0. 8-6.7) and 3.1 (0.7-10.9) for 11 and 13 years of latency, respectively] than were corresponding estimates for colon cancer [OR and CI, 1.3 (0.5-3.5) and 1.5 (0.3-5.8) for 11 and 13 years of latency, respectively]. These results provide evidence for an association between PCE-contaminated public drinking water and cancer of the lung and, possibly, cancer of the colon-rectum. (+info)
Alternatives to minimize the environmental impact of large swine production units. (4/712)Large swine production facilities have become controversial additions to the agricultural landscape as their numbers and sizes have increased. In addition to being larger enterprises, these units have involved greater specialization, the influx of outside capital, and the employment of labor without extensive investment in the enterprise. Major complaints have included water pollution and odors. Water pollution complaints have been related to surface and groundwater resources. Accidental spills, structural failure, and purposeful discharges have been noted. Odor problems are most often related to manure management techniques. Large anaerobic lagoons and irrigation of lagoon effluent have the potential to emit odors that travel long distances. Fortunately, technology and management alternatives exist to achieve higher levels of environmental acceptability. More effective water pollution and odor control alternatives generally increase construction and operating costs. Producers, regulatory officials, and the local public have an opportunity to interact to achieve progress in establishing acceptable compromises. This article identifies the range of existing and evolving alternative strategies and provides some assistance to producers and neighbors in achieving the necessary equilibrium. (+info)
Diversity of bacteroides fragilis strains in their capacity to recover phages from human and animal wastes and from fecally polluted wastewater. (5/712)Great differences in capability to detect bacteriophages from urban sewage of the area of Barcelona existed among 115 strains of Bacteroides fragilis. The capability of six of the strains to detect phages in a variety of feces and wastewater was studied. Strains HSP40 and RYC4023 detected similar numbers of phages in urban sewage and did not detect phages in animal feces. The other four strains detected phages in the feces of different animal species and in wastewater of both human and animal origin. Strain RYC2056 recovered consistently higher counts than the other strains and also detected counts ranging from 10(1) to approximately 10(3) phages per ml in urban sewage from different geographical areas. This strain detected bacteriophages in animal feces even though their relative concentration with respect to the other fecal indicators was significantly lower in wastewater polluted with animal feces than in urban sewage.

Epidemic and endemic seroprevalence of antibodies to Cryptosporidium and Giardia in residents of three communities with different drinking water supplies. (6/712)This study was carried out to compare cryptosporidiosis and giardiasis seroprevalence rates in residents of three communities. Community (Com 1) uses drinking water from deep wells, community 2 (Com 2) uses surface water from a protected watershed, and community 3 (Com 3) uses surface water frequently containing Cryptosporidium oocysts and Giardia cysts. Unfiltered drinking water from each community was collected at the tap and tested for Cryptosporidium oocysts and Giardia cysts during the 12 months in which sera were collected for testing. No oocysts or cysts were detected in the water from the Com 1 deep wells; oocysts and cysts were detected intermittently in the drinking water from the other two communities. A waterborne outbreak of cryptosporidiosis occurred in a municipality adjacent to Com 3 six months into this 12-month study. Sera from residents of each of the communities were collected proportionately by month and by population size. Coded sera were tested for IgG to Cryptosporidium using a previously developed Western blotting method. The presence or absence of bands at 15-17 kD and/or 27 kD was recorded for the 1,944 sera tested. Definite bands at 15-17 kD and/or 27 kD were detected in 981 (50.5%) of the sera. A total of 33.2% of sera from Com 1 (community using deep wells) were positive using the same criteria compared with 53.5% (Com 2) and 52.5% (Com 3) of sera from the two communities using surface drinking water. Both bands (15-17 kD plus 27 kD) were detected in 582 sera (29.9%) from the three communities: 14.1% of sera from Com 1 compared with 32.7% from Com 2 and 31.5% from Com 3. These findings are consistent with a lower risk of exposure to Cryptosporidium from drinking water obtained from deep well sources. However, analysis of results by calendar quarter showed a significant (P < 0.001) increase in the number of Com 3 positive sera (compared with Com 1) following the waterborne outbreak. Without this outbreak-related observation, a significant overall difference in seropositivity would not have been seen. We also observed that in sera from the community affected by the outbreak, the presence on immunoblots of both Cryptosporidium bands appeared to be the best indicator of recent infection. Seroprevalence rates using an ELISA to detect IgG to Giardia were estimated using the same sera. Overall 30.3% (590 of 1,944) of sera were positive by the ELISA. A total of 19.1% of sera from Com 1, 34.7% from Com 2 and 16.0% from Com 3 were seropositive. Rates for both Com 3 and Com 1 did not change significantly over time. In Com 2, rates decreased significantly (P < 0.001) during the last half of the study period (third and fourth calendar quarters). The reasons for the decrease in seroprevalence in Com 2 sera are presently not known. These studies show intriguing associations between seroprevalence, outbreak-related laboratory serologic data, and patterns of parasite contamination of drinking water. Further studies are required to validate the serologic approach to risk assessment of waterborne parasitic infections at a community level. (+info)
Potential contamination of drinking water with Toxoplasma gondii oocysts. (7/712)The world's first documented toxoplasmosis outbreak associated with a municipal water supply was recognized in 1995 in Victoria, British Columbia, Canada. It was hypothesized that domestic cat (Felis catus) or cougar (Felis concolor) faeces contaminated a surface water reservoir with Toxoplasma gondii oocysts. An extensive investigation of the Victoria watershed 1 year following the outbreak documented the presence of an endemic T. gondii cycle involving the animals inhabiting the area. Cats and cougars were observed throughout the watershed. Serological evidence of T. gondii infection was demonstrated among domestic cats living in the Victoria area. Cougars were found to shed T. gondii oocysts. Serological evidence of T. gondii infection in deer mice living in the riparian environments of the watershed suggested that T. gondii oocysts were being shed near the water edge. Contamination of Victoria's water supply with T. gondii oocysts potentially occurred during the study period and future waterborne toxoplasmosis outbreaks in this and other communities are possible.

Discriminant analysis of ribotype profiles of Escherichia coli for differentiating human and nonhuman sources of fecal pollution. (8/712)Estuarine waters receive fecal pollution from a variety of sources, including humans and wildlife. Escherichia coli is a ubiquitous bacterium in the intestines of warm-blooded animals and is used as an indicator of fecal pollution. However, its presence does not specifically differentiate sources of pollution. A total of 238 E. coli isolates from human sources (HS) and nonhuman sources (NHS) were collected from the Apalachicola National Estuarine Research Reserve, from associated sewage treatment plants, and directly from animals and tested for ribotype (RT) profile. HS and NHS isolates showed 41 and 61 RT profiles, respectively. At a similarity index of ca. 50%, HS and NHS isolates demonstrated four clusters, with the majority of HS and NHS isolates located in clusters C and D; isolates obtained directly from human and animal feces also could be grouped within these clusters. Discriminant analysis (DA) of RT profiles showed that 97% of the NHS isolates and 100% of the animal fecal isolates were correctly classified. The average rate of correct classification for HS and NHS isolates was 82%. We conclude that DA of RT profiles may be a useful method for identifying HS and NHS fecal pollution and may potentially facilitate management practices. (+info)
Water pollution - Wikipedia
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. 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 ...

Water pollution occurs when bodies of water become contaminated with substances that dont belong there and which are harmful to those who use the water, including plant, fish and animal life in and around it. 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 ...
Stopping Water Pollution in its Tracks: Nitrogen, Phosphorous, and the case for stormwater management | DeepRoot Blog
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 quality analysis using an inexpensive device and a mobile phone | Environmental Systems Research | Full Text
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 ...

Types of pollution : Water pollution
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 ...

Environmental Regulations, Air and Water Pollution, and Infant Mortality in India
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. ...

Using biological effects tools to define Good Environmental Status under the European Union Marine Strategy Framework Directive...
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.

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 ...
Water | Free Full-Text | Sources and Mechanisms of Low-Flow River Phosphorus Elevations: A Repeated Synoptic Survey Approach
High-resolution water quality monitoring indicates recurring elevation of stream phosphorus concentrations during low-flow periods. These increased concentrations may exceed Water Framework Directive (WFD) environmental quality standards during ecologically sensitive periods. The objective of this research was to identify source, mobilization, and pathway factors controlling in-stream total reactive phosphorus (TRP) concentrations during low-flow periods. Synoptic surveys were conducted in three agricultural catchments during spring, summer, and autumn. Up to 50 water samples were obtained across each watercourse per sampling round. Samples were analysed for TRP and total phosphorus (TP), along with supplementary parameters (temperature, conductivity, dissolved oxygen, and oxidation reduction potential). Bed sediment was analysed at a subset of locations for Mehlich P, Al, Ca, and Fe. The greatest percentages of water sampling points exceeding WFD threshold of 0.035 mg L−1 TRP occurred during

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.
Factors affecting farmers willingness to participate in eutrophication mitigation : a case study of preferences for wetland...
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 ...

Welcome to CDC stacks | Surveillance for waterborne-disease outbreaks--United States, 1997-1998 - 26709 | Stephen B. Thacker...
Interpretation: Drinking water outbreaks associated with surface water decreased from 31.8% during 1995-1996 to 11.8% during 1997-1998. This reduction could be caused by efforts by the drinking water industry (e.g., Partnership for Safe Water), efforts by public health officials to improve drinking water quality, and improved water treatment after the implementation of EPAs Surface Water Treatment Rule. In contrast, the proportion of outbreaks associated with systems supplied by a groundwater source increased from 59.1% (i.e., 13) during 1995-1996 to 88.2% (i.e., 15) during 1997-1998. Outbreaks caused by parasites increased for both drinking and recreational water. All outbreaks of gastroenteritis attributed to parasites in recreational water were caused by Cryptosporidium, 90% occurred in treated water venues (e.g., swimming pools and decorative fountains), and fecal accidents were usually suspected. The data in this surveillance summary probably underestimate the true incidence of WBDOs ...
How effective are created or restored freshwater wetlands for nitrogen and phosphorus removal? A systematic review protocol |...
Man-made eutrophication of aquatic environments is a major environmental problem in large parts of the world . This is also the case in Europe, where EU legislation (the Water Framework Directive and the Marine Strategy Framework Directive), international conventions (OSPAR, HELCOM) and national environmental objectives emphasize the need to reduce the input of plant nutrients to freshwater and marine environments. Furthermore, it is generally accepted that some of the reduction measures target agricultural runoff and other diffuse emissions of nitrogen and phosphorus.. One method to reduce the input of plant nutrients to freshwater and coastal waters is to let water pass through some kind of constructed or restored wetland. Major types of constructed wetlands include Free Surface Flow Constructed Wetlands, Subsurface Horizontal Flow Constructed Wetlands, and Subsurface Vertical Flow Constructed Wetlands, whereas restored wetlands refer to wetlands where interventions have been made to ...

Pathogenic E. Coli Pervasive In Stream-water Samples With Low Concentrations Of Fecal Indicator Bacteria | Ecology Press
Bacteria commonly used to indicate health risks in recreational waters might not be so reliable after all. Pathogenic E. coli were pervasive in stream-water samples with low concentrations of fecal indicator bacteria.. This is one of the unexpected findings from recent research that may affect how researchers and resource managers rely on indicator bacteria to determine if water is contaminated with bacteria that can make people sick. Although harmless themselves, fecal indicator bacteria such as nonpathogenic forms of E.coli, enterococci, and fecal coliform bacteria have long been used as an easy-to-measure surrogate to determine if pathogens are present.. We saw little relation between pathogenic E. coli and fecal indicator bacteria criteria for recreational waters, said Joseph Duris, U.S. Geological Survey (USGS), Michigan Water Science Center scientist who led the study. This is intriguing because we rely on indicator bacteria to tell us whether or not the water could make people sick, ...

Identifying and prioritizing the states most seriously polluted waters are important steps in the effort to reduce water pollution, said Judith Enck, EPA Regional Administrator. Since the Clean Water Act was adopted, water quality in New Jerseys rivers, lakes and streams has improved, but we still have a very long way to go. By investing in infrastructure and by implementing green infrastructure to control stormwater runoff, communities throughout New Jersey can improve water quality. Also, the New Jersey Department of Environmental Protection is tackling a decades-old problem by putting in place more stringent regulatory controls at combined sewage outfalls in the Camden and NY/NJ harbor areas. As New Jersey finalizes and fully implements these permits, we expect to see improvements in water quality ...
Multivariate statistical techniques for the assessment of surface water quality of Fuji River Basin, Japan | Water Supply | IWA...
Different multivariate statistical techniques were used to evaluate temporal and spatial variations of surface water-quality of Fuji river basin using data sets of 8 years monitoring at 13 different sites. The hierarchical cluster analysis grouped thirteen sampling sites into three clusters i.e. relatively less polluted (LP), medium polluted (MP) and highly polluted (HP) sites based on the similarity of water quality characteristics. The principal component analysis/factor analysis indicated that the parameters responsible for water quality variations are mainly related to discharge and temperature (natural), organic pollution (point sources) in LP areas; organic pollution (point sources) and nutrients (non point sources) in MP areas; and organic pollution and nutrients (point sources) in HP areas. The discriminant analysis showed that six water quality parameters (discharge, temperature, dissolved oxygen, biochemical oxygen demand, electrical conductivity and nitrate nitrogen) account for most ...
EPA Water Quality RTNLTR
Washington, DC 20460. Dear Mr. Mehan:. On June 29, 2001, the Environmental Protection Agency (EPA) Office of Water submitted a draft proposed rule titled Federal Water Quality Standards for Indian Country and Other Provisions Regarding Federal Water Quality Standards to the Office of Management and Budget (OMB) for review under Executive Order No. 12866. This proposed rule would establish Federal water quality standards for all Tribal waters except those already covered by EPA-approved Tribal standards, and those for which a Tribe requests deferred application of the Federal standards on the grounds that the Tribe will develop its own standards within a reasonable period of time.. Water quality standards are one of the fundamental tools provided by the Clean Water Act to restore and maintain the chemical, physical, and biological integrity of the Nations waters. The Act provides for States and Tribes to adopt such standards, generally on a waterbody, watershed, or ecoregion specific basis, ...

The Post-Oil Survival Guide for City Dwelling: Water Pollution & Purification
Water sources become contaminated from decades of acid rain and from industrial and agricultural runoff and sewage contamination during rainy seasons and snow meltoff. Fortunately the past few years have seen a decrease in pollution of all kinds due to the slowing down of industry, decreased use of petroleum-based materials, such as gasoline, motor oils, pesticides, etc., and most recently the complete halting of the domestic sewage system, reducing E. coli contamination in the lake. As well, thanks to the efforts of organizations such as the Lakewide Management Plan for the Great Leakes, plus the Environmental Protection Agency, phosphorous and mercury contamination since the end of the last century dwindled to nearly negligible levels. Despite these facts and the recent cessation of local sources of water contamination, the effects of pollution from this and the previous century will continue to contaminate rain and water bodies for countless years to come ...
Identifying human and livestock sources of fecal contamination in Kenya with host-specific Bacteroidales assays.
Microbial source tracking to distinguish between human, livestock and wildlife fecal pollution using molecular techniques is a rapidly evolving approach in many developed countries, but has not previously been applied on the African continent. DNA extracts from cow, donkey, and human fecal specimens and raw domestic sewage samples collected in Kenya were tested against five existing quantitative PCR assays designed to detect universal (2), human-specific (2), and cow-specific (1) fecal Bacteroidales genetic markers. Water samples from the River Njoro in Kenya were evaluated using the five tested Bacteroidales markers and a multi-species assay for Cryptosporidium in a preliminary exploration of fecal pollution sources and health risks in this watershed. Diagnostic sensitivity on the validation set varied from 18 to 100% for the five assays while diagnostic specificity was 100%. Of the 2 universal assays, Total Bacteroidales [Dick, L.K, Field, K.G., 2004. Rapid estimation of numbers of fecal ...

Source tracking of faecal indicator bacteria of human pathogens in bathing waters; an evaluation and development
Bacterial water pollution is a significant problem because it is associated with reduction in the quality of water systems with a potential impact on human health. Faecal indicator bacteria (FIB) are usually used to monitor the quality of water, and to indicate the presence of pathogens in water bodies. However, enumeration alone does not enable identification of the precise origin of these pathogens. This study aimed to monitor the quality of bathing water and associated fresh water in and out of the bathing season in the UK, and to evaluate the use of microbial source tracking (MST) such as the host-specific based polymerase chain reaction (PCR) and quantitative PCR (qPCR) to recognize human and other animal sources of faecal pollution. The culture-dependent EU method of estimating FIB in water and sediment samples was performed on beach in the South Sands, Kingsbridge estuary, Devon, UK- a previously problematic site. FIB were present at significant levels in the sediments, especially ...

A total of 765 Escherichia coli isolates from point and nonpoint sources were collected from the Apalachicola National Estuarine Research Reserve, and their multiple-antibiotic-resistance (MAR) profiles were determined with 10 antibiotics. E. coli isolates from point sources showed significantly greater resistance (P , 0.05) to antibiotics and higher MAR indices than isolates from nonpoint sources. Specifically, 65 different resistance patterns were observed among point source isolates, compared to 32 among nonpoint source isolates. Examples of this contrast in MAR profiles included percentages of isolates with resistance to chlortetracycline-sulfathiazole of 33.7% and to chlortetracycline-penicillin G-sulfathiazole of 14.5% for point source isolates versus 15.4 and 1.7%, respectively, for nonpoint source isolates. MAR profile homology, based on coefficient similarity, showed that isolates from point sources were markedly more diverse than isolates from nonpoint sources. Seven clusters were ...

Cascade effect (ecology)
An ecological cascade effect is a series of secondary extinctions that is triggered by the primary extinction of a key species in an ecosystem. Secondary extinctions are likely to occur when the threatened species are: dependent on a few specific food sources, mutualistic (dependent on the key species in some way), or forced to coexist with an invasive species that is introduced to the ecosystem. Species introductions to a foreign ecosystem can often devastate entire communities, and even entire ecosystems. These exotic species monopolize the ecosystem's resources, and since they have no natural predators to decrease their growth, they are able to increase indefinitely. Olsen et al. showed that exotic species have caused lake and estuary ecosystems to go through cascade effects due to loss of algae, crayfish, mollusks, fish, amphibians, and birds. However, the principal cause of cascade effects is the loss of top predators as the key species. As a result of this loss, a dramatic increase ...
