A General Discussion About Water Quality Testing
Water testing is a generalized description for a variety of methods used to test the quality of water at a specific point in time. Every time a municipal water testing center determines that there is need for a water test, it carries out a sample collection to establish the quality of the local water supply. This sample collection may take place on a daily, weekly or monthly basis. Hundreds of such water testing centers are located throughout the United States to meet the increasing demand for water testing services.

A number of reasons may result in the need for water testing. Samples may be required for: determining if treatment facilities are adequate to meet standards; determining if there are contaminants in the local water supply that have not been filtered out or removed; checking the effectiveness of anti-corrosion and chemical filters; determining the safety of new buildings and other structures built along the local waterway; and for the purpose of carrying out research concerning water quality testing. Another major use of water testing is to determine the rate of growth of bacteria and other harmful microorganisms in the water supply. Some water testing centers also undertake research and development activities aimed at helping communities cope with water-related problems. These problems include flooding, drought, excessive sewage, and the generation of chemical wastes by water-using plants.
The demand for professional water testing services is highly seasonal, as is the case in most industries. In the summer months, when businesses and individuals use water in greater quantities, the demand for water testing is accordingly much higher. However, even in the winter season, when people make use of fewer water resources, the number of samples collected from various localities is still quite high. Therefore, water testing laboratories are found in most places, including public offices, private homes, schools, companies, and other establishments. Many states regulate water testing, and there are several national organizations that provide guidelines for water quality testing.
