Hydrological and Geochemical Services
The importance of water-quality monitoring cannot be overstated. When the human body is comprised of 70 percent water, we require consumption of lots of water, and we hope that the water we are consuming has good quality. If not, short-term or long-term health effects may result from consumption of poor quality water. Aquatic resources (fish and invertebrates) may be affected detrimentally from poor quality water. A greater understanding of the coupled hydrologic/geochemical system can be achieved from water-quality monitoring.
Water-quality monitoring is sometimes done when there are regulatory concerns because certain constituents exceed acceptable standards for constituent concentrations in streams or drinking water. However, many times water-quality monitoring is done to know that good quality water does exist, and to make sure that the water quality remains good.
