Legionnaires' disease on a cruise ship linked to the water supply system: clinical and public health implications. (1/2621)The occurrence of legionnaires' disease has been described previously in passengers of cruise ships, but determination of the source has been rare. A 67-year-old, male cigarette smoker with heart disease contracted legionnaires' disease during a cruise in September 1995 and died 9 days after disembarking. Legionella pneumophila serogroup 1 was isolated from the patient's sputum and the ship's water supply. Samples from the air-conditioning system were negative. L. pneumophila serogroup 1 isolates from the water supply matched the patient's isolate, by both monoclonal antibody subtyping and genomic fingerprinting. None of 116 crew members had significant antibody titers to L. pneumophila serogroup 1. One clinically suspected case of legionnaires' disease and one confirmed case were subsequently diagnosed among passengers cruising on the same ship in November 1995 and October 1996, respectively. This is the first documented evidence of the involvement of a water supply system in the transmission of legionella infection on ships. These cases were identified because of the presence of a unique international system of surveillance and collaboration between public health authorities. (+info)
Needs assessment following hurricane Georges--Dominican Republic, 1998. (2/2621)Hurricane Georges struck the Carribean Islands in September 1998, causing numerous deaths and extensive damage throughout the region. The Dominican Republic was hardest hit, with approximately 300 deaths; extensive infrastructure damage; and severe agricultural losses, including staple crops of rice, plantain, and cassava. Two months after the hurricane, the American Red Cross (ARC) was asked to provide food to an estimated 170,000 families affected by the storm throughout the country. To assist in directing relief efforts, CDC performed a needs assessment to estimate the food and water availability, sanitation, and medical needs of the hurricane-affected population. This report summarizes the results of that assessment, which indicate that, 2 months after the disaster, 40% of selected families had insufficient food > or =5 days per and 28% of families reported someone in need of medical attention.

Comparison of large restriction fragments of Mycobacterium avium isolates recovered from AIDS and non-AIDS patients with those of isolates from potable water. (3/2621)We examined potable water in Los Angeles, California, as a possible source of infection in AIDS and non-AIDS patients. Nontuberculous mycobacteria were recovered from 12 (92%) of 13 reservoirs, 45 (82%) of 55 homes, 31 (100%) of 31 commercial buildings, and 15 (100%) of 15 hospitals. Large-restriction-fragment (LRF) pattern analyses were done with AseI. The LRF patterns of Mycobacterium avium isolates recovered from potable water in three homes, two commercial buildings, one reservoir, and eight hospitals had varying degrees of relatedness to 19 clinical isolates recovered from 17 patients. The high number of M. avium isolates recovered from hospital water and their close relationship with clinical isolates suggests the potential threat of nosocomial spread. This study supports the possibility that potable water is a source for the acquisition of M. avium infections. (+info)
High-performance liquid chromatography column switching applied to the trace determination of herbicides in environmental and drinking water samples. (4/2621)A selective and sensitive coupled-column high-performance liquid chromatographic method is developed for the simultaneous determination of 5 phenylurea herbicides (monuron, linuron, isoproturon, monolinuron, and diuron) in environmental and drinking water samples. Sample clean-up is performed automatically by means of a column switching technique. Using 2 octadecyl silica columns connected via two programmable 6-port valves and ultraviolet detection at 244 nm, the aforementioned compounds can be determined at the low concentration levels required for pesticide residue analysis in water samples. A mobile phase consisting of a mixture of methanol-water (55:45, v/v) is pumped at 1 mL/min. For the 5 phenylureas, high recoveries ranging from 94.9 to 101.6%, good reproducibility with relative standard deviations lower than 5%, and wide linear ranges up to 20 micrograms/L are observed with determination limits of 0.05 microgram/L. The method is successfully applied to the screening of different environmental water samples such as surface, ground, rain, and drinking water. (+info)
Tetrachloroethylene-contaminated drinking water in Massachusetts and the risk of colon-rectum, lung, and other cancers. (5/2621)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].

(6/2621)We conducted in vitro and in vivo assays in a selenium-deficient system to determine if organic matter (mainly fulvic acid; FA) is involved in a free radical mechanism of action for Kashin-Beck disease. Cartilage cell culture experiments indicated that the oxy or hydroxy functional groups in FA may interfere with the cell membrane and result in enhancement of lipid peroxidation. Experiments with rats demonstrated that toxicity from FA was reduced when the hydroxy group was blocked. Induction of lipid peroxidation by FA in liver and blood of rats was similar to that exhibited by acetyl phenyl hydrazine. FA accumulated in bone and cartilage, where selenium rarely concentrates. In addition, selenium supplementation in rats' drinking water inhibited the generation of oxy-free radicals in bone. We hypothesized that FA in drinking water is an etiological factor of Kashin-Beck disease and that the mechanism of action involves the oxy and hydroxy groups in FA for the generation of free radicals. Selenium was confirmed to be a preventive factor for Kashin-Beck disease. (+info)
Eradicating guinea worm without wells: unrealized hopes of the Water Decade. (7/2621)At the start of the United Nations International Drinking Water Supply and Sanitation Decade in the 1980s, guinea worm disease was targeted as the major indicator of the success of the Decade's efforts to promote safe water. By the late 1980s, most of the guinea worm endemic countries in Africa and South Asia had established guinea worm eradication programmes that included water supply as one of their main technical strategies. By surveying the water supply situation in Ifeloju Local Government Area (LGA) in Oyo State, Nigeria, in June 1996, as a case study, it was possible to determine the role that water supply has played in the eradication effort. Although two major agencies, the former Directorate for Food, Roads and Rural Infrastructure and UNICEF, provided hand dug and bore-hole wells respectively in many parts of the LGA, coverage of the smaller farm hamlets has been minor compared to efforts in the larger towns. This is ironic because the farm hamlets served as a reservoir for the disease in the 1980s, such that when the piped water system in the towns broke down, guinea worm was easily reintroduced into the towns. The survey of 188 ever-endemic hamlets with an estimated population of 23,556 found that 74.3% of the people still drink only pond water. Another 11.3% have wells that have become dysfunctional. Only 14.4% of this rural population has access' to functioning wells. Guinea worm was eliminated from 107 of the hamlets mainly by the use of cloth filters and chemical treatment of ponds. While this proves that it is possible to eradicate guinea worm, it fails to leave behind the legacy of reliable, safe water supplies that was the hope of the Water Decade. (+info)
Criteria for successful sanitation programmes in low income countries. (8/2621)In the International Drinking Water Supply and Sanitation Decade (1981-90), the development of a consensus on the concept of sanitation and the planning and implementation of effective and efficient sanitation programmes was not emphasized. Yet lack of good sanitation is a growing burden and environmental threat. Significant improvement of human health cannot be achieved without good environmental sanitation conditions and practices. A consensus on what makes a sanitation programme successful can help to conserve limited funds and spend those available more wisely. It will also help to reduce the increasing flows of waste poisoning precious sources of drinking water. This article was written to stimulate discussion on what attributes can be taken as characteristic of good environmental sanitation programmes, and on which indicators can be used to assess those attributes in actual sanitation programmes.

Integrated risk assessment and screening analysis of drinking water safety of a conventional water supply system | Water...
Management of drinking water safety is changing towards an integrated risk assessment and risk management approach that includes all processes in a water supply system from catchment to consumers. However, given the large number of water supply systems in China and the cost of implementing such a risk assessment procedure, there is a necessity to first conduct a strategic screening analysis at a national level. An integrated methodology of risk assessment and screening analysis is thus proposed to evaluate drinking water safety of a conventional water supply system. The violation probability, indicating drinking water safety, is estimated at different locations of a water supply system in terms of permanganate index, ammonia nitrogen, turbidity, residual chlorine and trihalomethanes. Critical parameters with respect to drinking water safety are then identified, based on which an index system is developed to prioritize conventional water supply systems in implementing a detailed risk assessment ...

NWA 2012 : Melbourne : Line item notes : 11.13 Entitled extraction of allocated groundwater to urban water system
During the 2011-12 year Melbournes urban water was sourced exclusively from surface water [11.12]; however in some years a very small proportion is sourced from groundwater [11.13]. While a desalination plant has been built to supplement Melbournes urban water supply, this was not operational during the 2011-12 year.. Urban water consumption [19.4] of potable and non-potable water was 330,632 ML during the 2011-12 year, representing almost 90% of all urban water supply system outflows. A very small volume of water was transferred out of the region via normal operations in Western Waters service area [19.11]. Non-revenue water, including pipes bursting [19.2], background leakage [19.3] and other losses [19.20], made up the remaining urban water supply system outflows.. The following figure shows all the inflows and outflows for the urban water supply system. For more detail on a particular flow associated with the urban water supply system, refer to the line item notes.. ...
Energies | Free Full-Text | Risk Assessment of Distribution Networks Considering the Charging-Discharging Behaviors of Electric...
Electric vehicles (EVs) have received wide attention due to their higher energy efficiency and lower emissions. However, the random charging and discharging behaviors of substantial numbers of EVs may lead to safety risk problems in a distribution network. Reasonable price incentives can guide EVs through orderly charging and discharging, and further provide a feasible solution to reduce the operational risk of the distribution network. Considering three typical electricity prices, EV charging/discharging load models are built. Then, a Probabilistic Load Flow (PLF) method using cumulants and Gram-Charlier series is proposed to obtain the power flow of the distribution network including massive numbers of EVs. In terms of the risk indexes of node voltage and line flow, the operational risk of the distribution network can be estimated in detail. From the simulations of an IEEE-33 bus system and an IEEE 69-bus system, the demonstrated results show that reasonable charging and discharging prices are

Developing a model for disinfection by-products based on multiple regression analysis in a water distribution system | Journal...
The characteristics of disinfection by-product (DBP) formation in the distribution system of Hiroshima City were investigated. Then a model was developed for predicting DBPs based on multiple regression analysis. Potassium permanganate consumption value (KMnO4), free chlorine residual concentration (Cl2), pH, water temperature (WT) and residence time (RT) were confirmed to have an influence on DBP formation in the distribution system and used as independent variables.. The correlation coefficients between the logarithmic values of the predicted DBPs and those of the observed DBPs were higher than 0.7. In addition, the seasonal change patterns of the predicted DBPs were very similar to those observed in some DBPs. The model is helpful for managing the DBPs in water distribution systems. ...
Reconciliation Strategy for the Western Cape Water Supply System - Study Area

ASMscience | Microbes in Pipes: The Microbiology of the Water Distribution System
Non-microbiologists may assume that the goal of water utilities should be the elimination of all microbes from our drinking water. But the water we drink has never been sterile; perfectly safe water contains millions of non-pathogenic microbes in every glassful. Like every other human built environment, the entire water distribution system - every reservoir, every well, every pipe, and every faucet - is home to hundreds or thousands of species of bacteria, algae, invertebrates, and viruses, most of which are completely harmless to humans. In April, 2012, the American Academy of Microbiology convened a colloquium to assess what is known about the microbial inhabitants of the water distribution system and to propose goals for advancing our understanding of these communities in order to enhance the safety of our drinking water and the resilience of our water infrastructure.

Private water supplies · East Ayrshire Council
All private water supplies in Scotland now have to be routinely tested in accordance with the Private Water Supplies (Scotland) Regulations 2006.. The frequency of testing depends on the size of the supply or the use it is being put to. Where a private supply is being used for a commercial activity such as meat processing or food production for example, sampling must be carried out annually. Commercial activity includes bed and breakfast or holiday lettings. Sampling is also on an annual basis where the supply serves fifty or more people. Small supplies are sampled every four years.. The cost of sampling is borne by the supply holders and varies depending on the analysis required. Grants may be available for the upgrading of sub-standard supplies.. Sampling and administration of the grant scheme is carried out by the Pollution Control Team within Environmental Health.. ...
Domestic water supply using rainwater harvesting - WRAP: Warwick Research Archive Portal
World-wide pressure on water resources is mounting as populations grow, consumption per capita increases, fossil water resources are mined and the climate changes. Domestic water usage is a significant component of water demand. Under favourable circumstances, it can be met in part or in whole by rainwater collected close to an individual dwelling. Interest in such systems is growing especially in rural areas where either rainfall is well distributed through the year, or where surface water is absent, groundwater mineralized and centralized piped supplies unaffordable. Roofwater collection is also being practised on low-rise and high-rise buildings in some cities having wet climates, The principles and components of rainwater harvesting are reviewed. Factors leading to the growing use of domestic rainwater harvesting in three different developing countries (North China, East Africa cmd Singapore) as case studies are discussed along with current practices, design options for system components ...
city water supply | BCB Property Management
With such a massive population, New York Citys water supply has its work cut out which is why the citys internal system still stands as one of the most intricate. The Big Apples water supply serves a span of 125 miles while delivering one billion gallons of drinking water to over nine million people.. As far as the origins of the citys water system - in 1842, the City decided to impound water from the Croton River via the Old Croton Aqueduct. The aqueduct had a capacity of about 90 million gallons per day. In 1883 the city then formed a commission to build a second aqueduct from the Croton watershed in addition to more storage reservoirs.. The Board of Water Supply was established in 1905 by the State Legislature as well as the Catskill region developed to be an additional water source for the city. The Board of Water Supply proceeded to plan and construct facilities to impound the waters of the Esopus Creek to deliver the water throughout NYC.. Water for this system is impounded in three ...

DUGi: Ítem | DUGiDocs - Automatic diagnosis of voltage disturbances in power distribution networks
DUGi: Viewing Item from repository DUGiDocs: This thesis proposes a framework for identifying the root-cause of a voltage disturbance, as well as, its source location (upstream/downstream) from the monitoring place. The framework works with three-phase voltage and current waveforms collected in radial distribution networks without distributed generation. Real-world and synthetic waveforms are used to test it. The framework involves features that are conceived based on electrical principles, and assuming some hypothesis on the analyzed phenomena. Features considered are based on waveforms and timestamp information. Multivariate analysis of variance and rule induction algorithms are applied to assess the amount of meaningful information explained by each feature, according to the root-cause of the disturbance and its source location. The obtained classification rates show that the proposed framework could be used for automatic diagnosis of voltage disturbances collected in radial distribution networks.

Find New England Sites - SAVAGE MUNICIPAL WATER SUPPLY WELL
The Savage Municipal Water Supply Well site covers approximately 235 acres, is located about 5 miles west of the center of Milford, and consists of a municipal well and the underlying aquifer. The Savage Municipal Well operated from 1960 to 1983, during which it supplied approximately 45 percent of Milfords drinking water, averaging about 200,000 gallons per day. The remainder of the Towns water supply was provided by the Keyes and Kokko Wells. Land uses within the site area include residential, agricultural, heavy and light industry, commercial enterprises, and aquaculture. Contamination was first discovered at the site as a result of a State-wide drinking water sampling program in 1983. The Savage Municipal Well and a nearby contaminated well supplying drinking water to a trailer park were later closed. At that time, the State began investigations to locate the source of contaminants that were also present in the wastes of nearby industries. Industry and fish hatcheries also withdraw water ...

Real Estate Council of British Columbia - Water Supply
In the case of unproven water supply from either an existing or a new source, the buyer will be concerned not only with quality but also with quantity.. When a property is connected to a municipal or community water supply, water is often taken for granted. The rural experience is often quite different - water conservation practices being the rule rather than the exception. When the water supply expected by the buyer disappears, the consequences can be disastrous.. During examinations for discovery in an Alberta case, the plaintiff buyers testified that the water supply was much less than capable of meeting their familys needs. As a result, a number of extraordinary measures were required. Two members of the family showered in the morning and the other members showered in the evening. They could not do any watering in the yard and they flushed the toilets only when absolutely necessary. That sort of evidence has the potential to generate considerable sympathy at trial..

Assessing biological stability of drinking water without disinfectant residuals in a full-scale water supply system | DORA Eawag
Biological stability refers to the inability of drinking water to support microbial growth. This phenomenon was studied in a full-scale drinking water treatment and distribution system of the city of Zürich (Switzerland). The system treats lake water with successive ozonation and biological filtration steps and distributes the water without any disinfectant residuals. Chemical and microbiological parameters, notably dissolved organic carbon (DOC), assimilable organic carbon (AOC), heterotrophic plate counts (HPC) and flow-cytometric total cell concentration (TCC), were measured over an 18-month period. We observed a direct correlation between changes in the TCC, DOC and AOC concentrations during treatment; an increase in cell concentration was always associated with a decrease in organic carbon. This pattern was, however, not discerned with the conventional HPC method. The treated water contained on average a TCC of 8.97 × 104 cells ml-1, a DOC concentration of 0.78 mg l-1 and an AOC ...
Eukaryotic community diversity and spatial variation during drinking water production (by seawater desalination) and...
In the drinking water samples taken at 5 tap locations in the same drinking water distribution network (Fig. S1,† TP1-TP5), different eukaryotic communities were identified within each of the tap water samples. These differences may reflect the existence of a variety of microhabitats defined by complex environmental conditions existing in the distribution network (reservoir, pipes and premise plumbing) that affect the eukaryotic community composition and structure. Both the number of shared eukaryotic groups and their relative abundance varied between the PW (drinking water feeding the network) and each of the tap water samples in the network (except Gastrotrich detected only in TP4). In addition, the taxonomic diversity of the fungal community in the network was higher than observed in the PW (Fig. S4†). Results showed that the core community shared between the PW and the all combined tap water samples was composed of 84 OTUs (28.1%). The core community between the PW and each of the tap ...

Sporadic Cryptosporidiosis Decline after Membrane Filtration of Public Water Supplies, England, 1996-2002 - Volume 11, Number 2...
The incidence of sporadic cryptosporidiosis among 106,000 residents of 2 local government districts in northwest England before and after installation of membrane filtration of public water supplies was compared to that of 59,700 residents whose public water supplies remained unchanged. A national outbreak of foot and mouth disease in livestock during 2001 was associated with a decline in sporadic human cryptosporidiosis in all regions of the United Kingdom. In a Poisson regression model, membrane filtration was associated with an estimated 79% reduction (incidence ratio 0.207, 95% confidence intervals 0.099-0.431, p < 0.0001) after adjustment for the interval of the foot and mouth disease epidemic and the water source. Despite the confounding effect of that epidemic, membrane filtration of the public water supply was effective in reducing the risk for sporadic human Cryptosporidium infection in this population.

United States Environmental Protection Agency - Wikipedia
On July 9, 1970, Nixon proposed an executive reorganization that consolidated many environmental responsibilities of the federal government under one agency, a new Environmental Protection Agency. This proposal included merging antipollution programs from a number of departments, such as the combination of pesticide programs from the United States Department of Agriculture, Department of Interior, and U.S. Department of Interior. After conducting hearings during that summer, the House and Senate approved the proposal. The EPA was created 90 days before it had to operate, and officially opened its doors on December 2, 1970. The agencys first Administrator, William Ruckelshaus, took the oath of office on December 4, 1970. In its first year, the EPA had a budget of $1.4 billion and 5,800 employees. At its start, the EPA was primarily a technical assistance agency that set goals and standards. Soon, new acts and amendments passed by Congress gave the agency its regulatory ...

Obsolete, Outdated, Improvable: Dams and Water Supply in the Carolinas | American Rivers
Sometimes, the solution needs some creativity. Ensuring reliable clean water supplies from our rivers and streams has been a strategy since the dawn of society. Historically, people built dams to create pools of water so that they could pipe water out of the pool. In many cases these water supplies are now in jeopardy as the dam ages. The question arises- can we remove the dam to restore the river and sustain the reliable water supply? American Rivers is working with communities along the Cape Fear River and the Tuckasegee River in the Carolinas to solve this question. Often, the solution requires big-picture thinking: Our priority is ensuring reliable clean water supplies for people and nature through all our work. It is a balance and area where we are pulling our communities of practice together to solve this problem. Can we use less water? On the Cape Fear River, American Rivers is working with communities to develop strategies- like greater water efficiency and eliminating wasted water- that ...

Framework for local government to implement integrated water resource management linked to water service delivery
Introduction Internationally, in recent years, a more integrated approach to the management of natural resources has been advocated. Integrated water resource management (IWRM) is such a process and it promotes the co-ordinated development and management of water and land so as to maximise economic and social welfare without compromising the sustainability of vital ecosystems (Global Water Partnership, 2000; DWAF, 2004a). One of the aims of IWRM is to improve all aspects of water resource management progressively - the way we collect water, store water, distribute water, conserve water and keep water pure. IWRM thus aims to find a balance between the social, environmental and technological perspectives of water resource management. The South African National Water Act (Act 36 of 1998) (NWA) promotes an integrated catchment-based approach to water resource management. The law promotes a more equitable and sustainable use of our water and makes water everybodys business. Since we all have a ...

Coliform bacteria found in GB drinking water
The City of Great Bend public water supply system violated a drinking water microbiological standard for total coliforms in its distribution system during September 2010, said Donald Craig, director of public works. Although this is not an emergency, you as customers have a right to know what happened and what is being done to correct the situation.. "We routinely monitor for the presence of total coliform bacteria in our drinking water 15 times a month tested in 15 different zones," Craig said.. "This is not an Emergency." Total coliform bacteria are generally not harmful themselves. Coliforms are bacteria which are naturally present in the environment and are used as an indicator that other; potentially-harmful, bacteria may be present.. Coliforms were found in more samples than allowed and this was a warning of potential problems, the director said. Usually coliforms are a sign that there could be a problem with the treatment or distribution systems (pipes). "Whenever we detect coliform ...

paul gregutt's washington wine blog - unfined & unfiltered: important public service announcement
5. Switching back to water - most modern water supply systems are far better and more bacteria free than the taste of the water might imply. For the statistic quoted above to be true, there would have to be almost 3 grams of E. Coli bacteria in each liter of water you drink. I could see that being the case in stagnant pond water, but theres no possible way that youd find anywhere near that amount in any sort of drinking water, once it was filtered and chlorinated. There might be a good deal of rust in your pipes, but harmful bacteria in the water supply are not usually a major concern in modern societies. And, when the water supply system does become contaminated for a short period of time, especially by harmful strains of E. Coli, warnings are posted just about everywhere ...
Performance of Household Water Treatment Methods for Microbial Removal under Household Conditions in Kabale District, Uganda
Despite the Ugandan government efforts to improve access to safe water sources, the rate at which diseases spread as a result of unsafe drinking water is absolutely high. The purpose the study was to assess the performance of household water treatment methods (HWT) and evaluate their ability to improve the microbial quality of drinking water under household conditions in Kabale District. We randomly selected 205 households, where we collected treated and untreated water samples. We analyzed 46 paired samples (untreated and treated) of drinking water from 46 households that reported treated water available. Samples were analyzed for total coliforms and Escherichia coli, the major indicators of biological contamination of drinking water, to measure effectiveness of treatment under household conditions. All reported HWT did not significantly improve the microbial quality of drinking water. Mean log10 total coliforms removal were 0.7 log10 (40.1%) for boiling method, 0.2 log10 (23.7%) for biosand ...

Adaptation of multiple regression analysis to identify effective factors of water losses in water distribution systems | Smart...
It is important to manage leaks in water distribution systems by smart water technologies. In order to reduce the water loss, researches on the main factors of water pipe network affecting non-revenue water (NRW) are being actively carried out. In recent years, research has been conducted to estimate NRW using statistical analysis techniques such as Artificial Neural Network (ANN) and Principle Component Analysis (PCA). Research on identifying factors that affect NRW in the target area is actively underway. In this study, Principle components selected through Multiple Regression Analysis are reclassified and applied to NRW estimation using PCA-ANN. The results show that the principal components estimated through PCA are connected to the NRW estimation using ANN. The detailed NRW estimation methodology presented through the study, as a result of simulating PCA-ANN after selecting statistically significant factors by MRA, forward method showed higher NRW estimation accuracy than other MRA methods.
Leech Water Supply Area (Future Water Supply) | CRD
The Leech Water Supply Area (WSA) consists of 92 % of the watershed area of the Leech River above the existing tunnel that will be used to divert water to Sooke Lake Reservoir.

Occurrence and Distribution of Ammonium in Iowa Groundwater: Ingenta Connect
Excess ammonium in groundwater may lead to nitrification or loss of chlorine residuals in public drinking water supplies. In Iowa, where groundwater supplies nearly 75% of all drinking water used in the state, naturally occurring ammonium is found in all major aquifers, including two unconsolidated units and five bedrock aquifers. An evaluation of ammonium concentrations in 841 municipal water supply wells indicated highest concentrations were found most often in Quaternary wells. More than one-half of all Quaternary wells sampled in Iowa showed ammonium concentrations greater than 2 mg/L, and more than 5% had concentrations greater than 5 mg/L. Nearly 5% of all bedrock wells used in this study showed ammonium concentrations greater than 2 mg/L. Aquifers overlain by carbon-rich Pennsylvanian strata or glacial drift seemed most vulnerable to elevated ammonium. Alluvial aquifers were least vulnerable to elevated ammonium concentrations in Iowa municipal water supplies. Ammonium concentrations ...
IBIS-PH - Health Indicator Report - Drinking Water: Arsenic
People drink and use water every day. The majority of Americans are provided with high quality drinking water. About 90% of people in the U.S. get their water from a community water system versus a smaller water supply, such as a household well. The U.S. Environmental Protection Agency (EPA) sets regulations for treating and monitoring drinking water delivered by community water systems. Currently, there are water quality standards and monitoring requirements for over 90 contaminants. Drinking water protection programs play a critical role in ensuring high quality drinking water and protecting the publics health. Because people drink and use water every day, contaminants in drinking water have the potential to affect many people. The number of people served by a community water system varies from as low as 25 to hundreds of thousands. Community water systems in the U.S. provide among the highest quality drinking water in the world. However, some contaminants are present at low levels and it is ...
