Source identification of surface water pollution using multivariate statistics combined with physicochemical and socioeconomic parameters.

Science of the Total Environment, 2021
Accurate identification of potential contamination sources of river water is a basis for effective pollution control and sustainable water management. Pollution source identification based on physicochemical-parameters-only method may lead to uncertainty

Sheep dip chemicals and water pollution

Science of The Total Environment, 1997
The Tweed River Purification Board's objective of reducing the numbers and significance of water pollution incidents by a proactive approach based on persuasion and education is described. This has consisted of prioritising potential pollutant sources which have then been investigated in detail followed by discussion and agreement with dischargers as ...

Bio-indicators and chemical pollution of surface waters

Environmental Monitoring and Assessment, 1983
Attention is given to two different approaches to determine the water quality in relation to toxic stress.The first approach is based on direct observations on the state of health of the biota naturally occurring in the environment to be judged. In the original concept of biological indicators of water pollution the existence of differences in stress ...

Water Pollution and Chemical Contamination in Drinking Water

1992
An ample supply of clean fresh water is essential for the well-being of all organisms. The quality of drinking water, often taken for granted in industrialized nations, is increasingly becoming a matter of concern. The original focus of most water quality improvement programs was on such conventional pollutants as dissolved oxygen, fecal coliform ...

Chemical Pollution of Ground Waters

Journal AWWA, 1974
As ground waters are increasingly used for water sources, contamination of ground water has become a problem in some areas. Among the contaminants are pesticides, trace elements, and nitrate—nitrogen. These contaminants are now being studied, and ways are being found to prevent or rectify their intrusion.

Chemical Water Pollution and Human Health

2017
Human activities associated with environmental degradation are threatening urban and rural water supplies throughout the world. Although water quality in the United States surpasses that in most of the world, increasing challenges from an aging infrastructure, poorly controlled disposal of pharmaceuticals, household chemical products, and biologically ...
