Potential health implications of water resources depletion and sewage discharges in the Republic of Macedonia
Potential health implications of deficient sanitation infrastructure and reduced surface water flows due to climate change are examined in the case study of the Republic of Macedonia. Changes in surface water flows and wastewater discharges over the period 1955–2013 were analyzed to assess potential future surface water contamination trends. Simple model predictions indicated a decline in ...

University of Washington portal - Case Study
Active Treatment and Wheel Wash Water Treatment In late 2008 construction began on the 3-year Seattle Light Rail University of Washington link connecting the university with downtown Seattle. Because this site drains to Lake Washington and the Montlake Cut the City of Seattle has put extra emphasis on protecting surface water from contaminated stormwater runoff. In fact, the city routinely ...

Hydrogeomorphological Controls on Groundwater Quality in the Rattaphum Catchment (Songkhla Lake Basin), Thailand
The Rattaphum Catchment comprises four major hydrogeomorphic units: mountains, footslopes, plains and inland swamps around a lake system. The area accommodates three main agroecosystems: vegetable, rubber and fruits. During the high-rainfall period, groundwater levels rise near to the soil surface in all agro-ecosystems. The high water levels remain for 3–4 months in the coastal plain, while in ...

Modelling the hydrologic effects of land-use and climate changes
Climate and land use affect water quantity and quality; however, the complex relations of climate and land use regarding flow and instream nutrient levels have yet to be elucidated. This study aims to assess the hydrologic effects of different land-use and climatic regimes in the Lower Great Miami River Basin. The modelling results from BASINS showed that, as expected, agricultural lands and the ...

Pollution and its impact on Noyyal river basin, India: an integrated approach of remote sensing and biotechnology using GIS
Numerous surface and ground water resources have been polluted by industries located around the river Noyyal, India. The water quality has been estimated to define the impact of contaminants in the study area. Fish sample (O.mosaambicus) has been collected from different locations. An elevated level of RBC, WBC count and changes in total percentage has been observed. Glutathione peroxidise ...

What you should do if brown water comes out of the pipe?
Especially in older properties, ungalvanized or galvanized iron pipes are often still installed in the water system. They tend to corrode. So the water flowing through them carries the rust with it. Whether you need hot or cold water - the number of rust particles is higher than average and a brownish liquid flows out of your faucet. However, the problem does not lie with your water supplier or ...

Reducing the Costs of Water and Wastewater Treatment Pipelines
When existing infrastructure is ready to be replaced, decentralized treatment can greatly reduce CAPEX and OPEX A stunning two thirds of capital expenditures for conventional wastewater treatment plants can go toward pipelines and pumping stations to maintain flow. Once built, large-scale central treatment plants deliver high quality water and savings through economies of scale, but they are ...

From Microbiotest to Decision Support System : an Assessment Framework for Surface Water Toxicity
Abstract : A decision framework for the site-specific detection of toxic effects of contaminants in surface waters is presented. Although the main objective of the development of this framework aimed at supporting water quality boards in their studies on polluted waters and sediments, it could also be of wider use. The decision framework is illustrated by means of a case study on a ditch that is ...

Passive samplers for chemical substance monitoring and associated toxicity assessment in water
The European legislation, and in particular the Water Framework Directive requires the development of cost efficient monitoring tools that can provide the required information for the assessment of water contamination. Passive sampling methods represent one of the novel tools that have a potential to be used in various regulatory monitoring programmes aimed at assessing the levels of chemical ...

Residual indicator bacteria in autosampler tubing: a field and laboratory assessment
Microbial contamination in surface waters has become a worldwide cause for concern. As efforts are made to reduce this contamination, monitoring is integral to documenting and evaluating water quality improvements. Autosamplers are beneficial in such monitoring efforts, as large data sets can be generated with minimized effort. The extent to which autosamplers can be utilized for microbial ...

A performance assessment of arsenic-iron removal plants in the Manikganj District of Bangladesh
In Bangladesh, arsenic contamination of groundwater, microbial contamination of surface water and seasonally variable rainfall make reliable access to acceptable quality drinking water a challenge. Arsenic-iron removal plants (AIRPs) are a relatively inexpensive way of removing arsenic from groundwater for access to safer drinking water. This study evaluated the performance of 21 (of 105) AIRPs ...

Assessing the microbial quality of a tropical watershed with an urbanization gradient using traditional and alternate fecal indicators
Urbanization affects the microbial loading into tropical streams, but its impact on water quality varies across watersheds. Rainfall in tropical environments also complicates microbial dynamics due to high seasonal and annual variations. Understanding the dynamics of fecal contamination in tropical surface waters may be further hindered by limitations from the utilization of traditional ...

The use of antibiotic resistance profiling as a means of tracing sources of fecal contamination in source waters
Fecal contamination of source waters and its associated intestinal pathogens continues to pose risks to public health although the extent and effect of microbial contamination of source waters gets very little attention in designing treatment plants in most developing countries. Coliform counts give an indication of the overall bacterial contamination of water and thus its safety for human ...

Assessing Ecological Risks to the Fish Community from Residual Coal Fly Ash in Watts Bar Reservoir, Tennessee
Extensive site‐specific biological and environmental data were collected to support an evaluation of risks to the fish community in Watts Bar Reservoir from residual ash from the December 2008 Tennessee Valley Authority (TVA) Kingston ash release. This paper describes the approach used and results of the risk assessment for the fish community, which consists of multiple measurement endpoints ...

What classifies as water pollution and why is it an issue?
The UN declared 2005-2015 as the International Decade for Action ‘Water for Life’. Yet each day thousands of people still die as a result of contaminated water. This does not even take into account the millions of organisms that perish every year thank to polluted water sources. Water pollution is a huge issue that is made more so by the fact that unfortunately, water is easily ...

Emerging Contaminants in Water in Africa
Access to clean and safe drinking water is a fundamental human right, yet a significant portion of the global population still lacks this essential resource. In Africa, the issue of water quality is of paramount concern, as many regions face challenges related to pollution and contamination. Emerging contaminants in water have become a pressing issue, as they pose potential risks to human ...
