The change of nonpoint source and freshwater discharge as a result of land use change might affect the water quality in a river. In the current study, a coupled three-dimensional hydrodynamic and water quality model was created and applied to the Danshuei River estuarine system and its adjacent coastal ocean. The hydrodynamic and water quality models were validated using observations of water surface elevation, salinity distribution and water quality state variables. The predictions of hydrodynamics, salinity, dissolved oxygen and nutrients from the model simulation quantitatively agreed with the observational data. The validated model was then used to investigate the possible effects of the nonpoint source and freshwater discharge changes at the upstream reaches on water quality conditions in the Danshuei River estuarine system. Three scenarios were investigated to predict the dissolved oxygen using model simulations. The simulated results indicated that increasing nonpoint sources at the upstream

Abstract. When water supplies are compromised during an emergency, responders often recommend household water treatment and safe storage (HWTS) methods, such as boiling or chlorination. We evaluated the near- and longer-term impact of chlorine and filter products distributed shortly after the 2010 earthquake in Haiti. HWTS products were deemed as effective to use if they actually improved unsafe household drinking water to internationally accepted microbiological water quality standards. The acute emergency survey (442 households) was conducted within 8 weeks of emergency onset; the recovery survey (218 households) was conducted 10 months after onset. Effective use varied by HWTS product (from 8% to 63% of recipients in the acute phase and from 0% to 46% of recipients in the recovery phase). Higher rates of effective use were associated with programs that were underway in Haiti before the emergency, had a plan at initial distribution for program continuation, and distributed products with community
Good water quality is important for the people and nature. We use surface water to produce drinking water, to fish in and for leisure pursuits. Much of Dutch nature is dependent on water from lakes, ponds, streams and rivers.. Pollution by industry and households has significantly reduced since the nineteen seventies because the government started to impose rules on the discharging of water. Since then, although the physical and chemical water quality has improved significantly, work still needs to be done on the ecological water quality. One of the reasons for this is that it always takes a while before the ecology responds to improved water quality.. At this moment in time the most important causes of insufficient water quality are:. ...

Water is a critical resource for all life. With roughly 3% of the water on earth being fresh water, and of that percentage about 1 % being available to humans, it is clear to see the importance of protecting the water that is available to us. Globally, factors such as climate change, population growth, increasing industrialization and loss of natural resources are all aiding in the reduction of fresh water quality and quantity. This paper addresses local water quality issues, in hopes of gaining a better understanding of issues seen locally, which also occur in many other locations worldwide. Gallatin Valley located in Gallatin County, Montana is the selected study area for this research. The study area has a diverse landscape, which allowed for a unique study, examining many anthropogenic and natural sources of nitrate-N. These sources and the nitrate-N levels associated with them were the main focus for this research. Using well water quality tests from various organizations, data was managed ...

This work is about finding an appropriate modelling complexity for a mass-balance model for phosphorus in Lake Vänern, Sweden. A statistical analysis of 30 years of water quality data shows that epilimnion and hypolimnion have different water quality and should be treated separately in a model. Further vertical division is not motivated. Horizontally, the lake should be divided into the two main basins Värmlandssjön and Dalbosjön. Shallow near shore ares, bays and areas close to point sources have to be considered as specific sub-basins if they are to be modelled correctly.. These results leads to the use of a model based on ordinary differential equations. The model applied is named LEEDS (Lake Eutrophication Effect Dose Sensitivity) and considers phosphorus and suspended particles. Several modifications were made for the application of the model to Lake Vänern. The two major ones are a revision of the equations governing the outflow of phosphorus and suspended particle through the outflow ...

... A drainage utility is: a financing mechanism, providing a stable and dedicated funding source for surface water quality and quantity control; and a governmental entity whose mission is to provide surface water quality and quantity control. Drainage utilities have come into being to address largely the flooding and water quality problems associated with urbanization and separated storm sewers. Even when some of the worst impacts are addressed on the site of the development through detention, water treatment, etc., some organization must make it its responsibility to see that these mitigation mechanisms continue to work, receive maintenance and to take care of the residual effects that cannot be addressed completely on site. This paper discusses the Bellevue Storm & Surface Water Utility to illustrate what a drainage utility can provide and why any urbanizing area today should strongly consider the creation of one to control surface water runoff and funding from other than

To form a baseline study of a proposed county ditch, nutrient levels (PO4-P, TKN, and NO3-N), conductivity, and turbidity were monitored during 1980 at eight sites along the stream proposed to be channelized. Tributaries from three partly drained wetlands and four drainage ditches were also sampled to compare wetland and ditch outputs and to access their impact on the streams water quality. The predominantly agricultural watershed (4554 acres) of the stream was dissected into the tributary subsheds and the percentages of different land use categories, the numbers of animals, drainage histories, and soil types were compiled for these watersheds and examined for relationships to water quality differences in the tributaries. Significant differences in nutrient concentrations were found among the wetland and drainage ditch outputs ranging from the most distinct wetland (PO4-P, TKN, and NO3-N means of 0.919, 3.42, and 0.24ppm) to the most distinct drainage ditch (PO4-P, TKN, and NO3-N means of ...
Infrastructural problems force South African households to supplement their drinking water consumption from water resources of inadequate microbial quality. Microbial water quality monitoring is currently based on the Colilert®18 system which leads to rapidly available results. Using Escherichia coli as the indicator microorganism limits the influence of environmental sources on the reported results. The current system allows for understanding of long-term trends of microbial surface water quality and the related public health risks. However, rates of false positive for the Colilert®18-derived concentrations have been reported to range from 7.4% to 36.4%. At the same time, rates of false negative results vary from 3.5% to 12.5%; and the Colilert medium has been reported to provide for cultivation of only 56.8% of relevant strains. Identification of unknown sources of faecal contamination is not currently feasible. Based on literature review, calibration of the antibiotic-resistance spectra of

Water quality in California is regulated by several state agencies, including the State Water Resources Control Board (State Water Board) and its nine regional boards, which enforce clean water laws and the Department of Public Health.. Water quality concerns are also often involved in disputes over water rights, particularly in situations involving endangered species or habitat.. The State Water Board administers the Clean Water Grant Program that funds construction of wastewater treatment facilities. The State Water Board also issues general permits for municipalities and construction sites that try to prevent contaminants from those sources from entering municipal storm sewers.. Drinking water standards and regulations are developed by federal and state agencies to protect public health. In California, the Department of Public Health administers the federal Safe Drinking Water Act, which regulates drinking water quality in the United States.. ...
Water quality is reflective of activities taking place upstream of surface waters. In general, water quality is very high in Glacier National Park as it sits at the headwaters of the North American continent. From Triple Divide Peak water flows north to the Hudson Bay, west to the Pacific Ocean and south to the Gulf of Mexico. Glaciers protected mountain landscapes provide clean cold headwaters to the streams and tributaries further downstream. Park waters are classified A1, the highest standard specified by the state water quality bureau. Preserving and protecting water resources, and the plant and animal communities they support, is fundamental to the National Park Service mission. However, water is vulnerable to impacts from outside, as well as within, the park such as road construction, mining, recreational activities, and deposition from atmospheric pollutants.. For example, pollution carried in by rain, snow and airborne particulates is showing up in glacial lakes. This provides park ...

Cattle exclusion fencing has been recommended as a best management practice for the control of sediment, phosphorus, and nitrogen pollution in agricultural streams for several decades. The effectiveness of this practice for water quality improvement is varied. This review summarizes the findings of seventeen water quality studies where monitoring extended for up to 5 years. In general, cattle exclusion fencing decreased TSS and TP. The effect on dissolved forms of nutrients is more tenuous. Grazing cattle impact streams by damaging stream banks, kicking up streambed sediment, directly defecating into the water, and increasing polluted runoff risk in riparian areas. Improved study design and stream restoration practices may aid in increasing the understanding of the connection between riparian ecosystem recovery and water quality ...

This document is one in a series which establishes ambient water quality guidelines (criteria) for British Columbia. These are used to set ambient water quality objectives to protect the most sensitive designated water use in a specified body of water. The water uses protected include raw drinking, public water supply, and food processing water, aquatic life and wildlife use, agricultural use including livestock watering and irrigation, recreation and aesthics and industrial water supplies.
The industrial stormwater program is part of the National Pollutant Discharge Elimination System (NPDES) under the Clean Water Act (CWA) and is intended to preserve, protect, and restore surface water quality. Stormwater runoff is a leading source of water quality impairment in Arizona and nationwide. Stormwater leaving industrial sites is often conveyed by storm sewer systems directly to rivers and streams without any treatment, which can degrade water quality, habitat, and limit recreational uses. Activities such as material handling and storage, equipment maintenance and cleaning, industrial processing and other operations that occur at industrial facilities are often exposed to stormwater. The runoff from these activities can result in the discharge of pollutants directly into nearby water bodies or indirectly through storm sewer systems. Industrial runoff is also known to create physical hazards that pose drainage problems because the runoff carries pollutants from driveways, parking lots, ...

In open water systems, keeping both water depths and water quality at specified values is critical for maintaining a healthy water system. Many systems still require manual operation, at least for water quality management. When applying real-time control, both quantity and quality standards need to be met. In this paper, an artificial polder flushing case is studied. Model Predictive Control (MPC) is developed to control the system. In addition to MPC, a forward estimation procedure is used to acquire water quality predictions for the simplified model used in MPC optimization. In order to illustrate the advantages of MPC, classical control [Proportional-Integral control (PI)] has been developed for comparison in the test case. The results show that both algorithms are able to control the polder flushing process, but MPC is more efficient in functionality and control flexibility. ...
Dear Editor,. We write as concerned health professionals who seek to draw the publics attention to the dangers associated with hydraulic fracturing (fracking) and shale gas extraction in the United Kingdom, as highlighted by a recent report published by Medact. Fracking is an inherently risky activity that produces hazardous levels of air and water pollution that can have adverse impacts on health. The heavy traffic, noise and odour that accompanies fracking, as well as the socially disruptive effects of temporary boomtowns and the spoilage of the natural environment are additional health hazards. Such risks would be magnified in the UK where fracking is projected to take place in closer proximity to more densely populated communities; and where there are concerns about the effectiveness of the regulatory system for onshore gas extraction.. But in addition to this, shale gas is not a clean source of energy. Methane is a potent greenhouse gas in its own right, and when burnt, produces carbon ...

Effects of selective forest clearing on water yield and water quality were investigated in a 308-hectare basin that drains to Quabbin Reservoir Watershed in central Massachusetts. The experimental basin and a nearby 280-hectare control basin were studied together for comparison. Streamflow was measured continuously and water-quality samples were collected biweekly in both basins from February 1985 through September 1989. During the same period, measurements of precipitation quantity and ground- water levels were made and samples were collected for determination of precipitation and ground-water quality. After an initial monitoring period to establish baseline hydrology and water quality in both basins, an area of red pine and white pine forest in the experimental basin was cleared. From October 1986 until April 1987, 23.8 percent of the total basal area was removed by clearcutting and thinning. Part of the cleared area was converted to rye and other field grasses, and the remainder was...
The quality of water, whether it is used for drinking, irrigation or recreational purposes, is significant for health in both developing and developed countries worldwide. Water quality can have a major impact on health, both through outbreaks of waterborne disease and by contributing to the background rates of disease. Accordingly, countries develop water quality standards to protect public health.
Itaipu dedicates special care to the preservation of water, its main asset.. To protect it, the power plant maintains a watershed management program [1], whose purpose is to decrease the entry of sediments and chemical products into its reservoir.. According to the monitoring of the Paraná Environmental Institute (Instituto Ambiental do Paraná - IAP), the reservoir water at Itaipu is free from fecal coliforms and bacteria that could cause diseases in humans beings. According to IAP, there is no form of sewage emissions that may influence the quality of the water.. The concern for water quality led the company to create in 1977 a program for the permanent monitoring of the Paraná River and its tributaries, which contribute the water that feeds the Itaipu reservoir, formed in 1982.. The environmental programs developed by Itaipu have helped preserve the aquatic biodiversity and ensure its multiple applications without compromising the power plants operations.. Maintaining the water quality ...
Multivariate techniques, like cluster analysis (CA) and principal component analysis (PCA) were used to evaluate the spatial and temporal variability of surface water quality in a large neotropical hydroelectric reservoir (Nova Ponte Reservoir). The dataset, obtained during the period of 1995-2011 from the Energy Company of Minas Gerais State (CEMIG), contain 14 parameters surveyed quarterly in 14 sites, at different depths. The CA grouped the 14 sites in three main groups: lotic sites, half of the photic zone sites and bottom sites. Statistical tests showed that only three parameters (total dissolved solids, nitrate and chemical oxygen demand) have no significant difference between cluster groups. The PCA results showed temporal changes of the water quality in all groups, illustrating modifications to the importance of the parameters over time. PCA also revealed the major causes of water deterioration from 1995 to 2005 were related to agricultural and livestock activities. Currently, the water ...
The monitoring of water quality in large coastal regions demands great analytical efforts through the collection of many samples, over long periods. Remote sensing is a reliable tool that can provide valuable information on the spatial and temporal variations of environmental parameters, particularly turbidity and chlorophyll a. The aim of the present research was to evaluate the spatial and temporal distribution of water quality from 2005 to 2017 along the north coast of São Paulo and its responses to the implementation of industrial developments and to variations in rainfall. Fifty-two MODIS images were used, showing concentrations of chlorophyll a and turbidity, in the dry season and wet season, from 2005 to 2017. The results showed that dilution processes (due to rainfall) control chlorophyll a concentrations. However, a notable increase in concentrations could be identified after the installation of some of the developments in the region, particularly roads and ports. Turbidity was also shown to

By Laura McVicker, The Columbian, Vancouver, Wash. Jul. 31--Significantly higher-than-normal water temperatures and low oxygen levels in Burnt Bridge Creek have prompted a $500,000 state study to find ways to improve the creeks water quality and fish habitat. The creek is among the worst in Southwest Washington when it comes to meeting the states water quality standards. Fecal coliform, which has been found in high levels, poses health risks to humans; the warm water endangers the creeks fish wildlife, according to Tonnie Cummings, the Department of Ecologys water cleanup coordinator. "We dont know what the sources are in this case," Cummings said. "But, hopefully, the study will help us identify those.". The first part of the testing began this week. It included the release of a fluorescent dye into the stream Tuesday night to monitor water flows. The harmless dye dissipated within minutes, and allowed scientists to gauge how long it takes water to flow downstream as a way of pinpointing ...

Cluster analysis was performed to gain an overview of the association of bacterial communities at the four sampling stations during June and December (Fig. 5). UPMGA dendrograms showed grouping of samples according to season. June samples showed high similarity (, 94%) among bacterial communities for Vaal Barrage, Parys and Scandinawieë Drift. A similar trend was observed for the December samples where Vaal Barrage and Scandinawieë Drift were defined by a 100% similarity. Noticeable was the grouping of the December Parys and Deneysville samples (100% similarity). Grouping of these two sampling sites may be attributed to similar banding patterns of a few dominant DGGE bands (Fig. 2). Diversity indices (H) and cluster analyses could be associated with DGGE profiles which reflected variations in the distribution, abundance and composition of bacterial taxa.. Multivariate analysis. PCA and RDA were performed to analyse the relationships between the environmental parameters and the clustering of ...

The Indiana Department of Environmental Management (IDEM) has begun developing a Total Maximum Daily Load (TMDL) for the Deep River-Portage Burns Watershed in Lake and Porter counties at 1 p.m., Thursday, Dec. 5, at the Lake County SWCD & Extension Office, 880 E. 99th Court, Suite A, in Crown Point. IDEM will provide a midterm report for the public, at a meeting.. TMDL is the term for a calculation to determine the maximum amount of pollutants, or pollutant load, a stream can receive and not violate state water quality standards. Where streams violate water quality standards, IDEM develops TMDL reports that include calculations and describe sources of pollutants within the watershed, methods used to analyze data, pollutant reductions needed to restore water quality, and actions for improving water quality.. Citizens who attend the meeting on the Deep River-Portage Burns Watershed TMDL will learn about water quality monitoring that began on April 2013, steps in the TMDL process, how the community ...
Application of aluminum (Al) salts has been used to reduce phosphorus (P) concentrations in lakes since the 1960s. Al is typically applied to the water column where Al-hydroxides form, settle to the sediment surface, and bind P in sediment. Al can be transported to other, non-target areas of the lake, however, potentially limiting treatment effectiveness. To alleviate this problem, a new method has been developed in which the Al salt is injected directly into the sediment as a liquid. In this study, the binding efficiency and application costs were calculated for 2 lakes in Sweden that received injection applications of polyaluminum chloride (PAC). Binding efficiency was similar to previous water column applications, implying there is little difference between the 2 application methods. Other factors, however, such as dissolved organic matter and type of Al salt used (PAC vs. Al sulfate), can also affect binding efficiency. Thus, Al injection may have improved the amount of P bound per unit Al ...

Summer Monitoring:. Many councils monitor popular recreational sites weekly over the summer months. This lets swimmers know what the most recent bacteria (enterococci) levels were. Remember, even for sites where the monitoring has shown an acceptable to swim test result, some conditions can make them unsuitable to swim in from time to time and we recommend that you avoid swimming after heavy rainfall for 48 hours.. Overall Recreation Risk:. The Overall Recreation Risk is a guide to give a general picture of water quality at a site over the recreational bathing season. Updated annually, it is calculated from bacteria (enterococci) data collected over the last three years during the summer monitoring months. The Overall Recreation Risk indicator is a precautionary approach to managing health risk and is not designed to represent health risk on a particular day. As such, a site can have an Overall Recreation Risk of Caution but still be suitable for swimming some of the time. See the factsheet on ...

Denitrifying biofilters are a promising and low-maintenance technology for removing nitrate from agricultural drainage, capable of removing 50-80% of annual nitrate loads. Because increased riverine nitrate concentrations are correlated with indicators of eutrophy and degradation of coastal waters, including a large hypoxic zone in the Gulf of Mexico (Turner and Rabalais 1994; Lohrenz et al. 1997; Rabalais and Turner 2001), denitrifying biofilters have the potential to substantially improve surface water quality. However, our understanding of ecological factors influencing biofilter performance was limited. Therefore, in this study, the microbial community of the biofilter was described using several different techniques. Denitrifying enzyme assays with inhibition showed that denitrification is primarily mediated by bacterial populations, but that fungi are also indirectly important. These assays also showed that denitrification occurs both on the surface of the biofilter woodchip media and in ...

Mike Waite, FWR Water Supply Co-ordinator. There were many informative papers presented at this meeting, on a broad range of topics, and only a flavour can be given here.. Tim Latcham described Bournemouth Water s use of a floating solar-powered ultrasound source with internal quality monitors to control algal blooms.The system was provided by a Dutch company and quality results were telemetered to them and they then advised on the sound requirements. The ultrasound is said to prevent algae from getting to the reservoir surface, thereby red ucing access to light, and will also cause some cell disruption. Results to date have been inconclusive but the company has been able to increase the proportion of River Stour water feeding the works.. Helen Pickett outlined an approach to automated coagulant control developed by Severn Trent. Coagulation destabilises the charge on particles and stops repulsion.

The soils in the Red River Valley (RRV) are generally fine textured and drain very slowly. At the same time, the RRV also receives the lowest amount of annual rainfall compared to the rest of the state. That rainfall is not distributed evenly throughout the year, with excessive moisture commonly present during spring and less precipitation later during the growing season.. The focus of this project is to monitor water quality, water table level, and yield in the proposed subirrigated corn field. The field will be split into three different zones. Each zone will be managed differently in respect to controlled drainage and sub-irrigation management. Soil moisture sensors placed in the field, along with rain gauges will help determine the need for sub-irrigation. Zone one will be managed as a conventional tile system that is open all year and sub-irrigation will not be used. The water table on zones two and three will be managed at different heights throughout the growing season by changing the ...
