What is the first step in controlling organic chemicals in drinking water?

The first step in controlling organic chemicals in drinking water involves conducting sanitary surveys to identify sources, types, and amounts of pollutants. This foundational approach is critical because it provides the necessary information about the specific contaminants present in a water supply, their origins, and the extent of their presence. Understanding these factors allows for targeted and effective management strategies.

By performing a thorough survey, sanitarians can assess potential pollution sources, such as industrial discharges, agricultural runoff, or sewage contamination. This information is essential for determining the nature of the organic chemicals that may be present and for planning appropriate interventions. Ultimately, without this initial step of identifying and assessing pollutants, subsequent actions, such as selecting treatment methods or upgrading treatment plants, would lack the specificity needed to effectively address the issues at hand.
