How can water consumers learn about atrazine test results in their water supply?
A public water supplier is required to monitor for atrazine according to a schedule as directed by the federal Safe Drinking Water Act, then provide an annual water quality report to consumers. Reports include information on the source of the system’s water along with results of testing done on the water during the previous calendar year. The Department of Health coordinates compliance and has the authority to ensure safe drinking water in all public drinking water supplies. Contact the Department of Health for additional information on detections of atrazine in public water supply systems. Private drinking water supplies (i.e. private wells) are not routinely regulated for contamination by any state agency; however, state agencies, local units of government, and non-governmental organizations conduct sampling and analysis of private wells through special projects. Detections of atrazine in private water supplies typically occur in areas that have sandy soils and/or shallow water table
