Aspects of Drinking Water Quality Technical Brief (DWQT)

This brief discusses four aspects of drinking water quality that may affect health or acceptability of drinking water. Microbiological contaminants (pathogenic bacteria, viruses, protozoa, and helminths) cause many of the most common diseases related to drinking water quality, including many diarrheal diseases. Some chemical contaminants, such as fluoride, arsenic and nitrate can cause widespread health effects. The acceptability of drinking water may influence people to use water sources that could be harmful to their health.
