Monitoring the quality of our drinking water is a joint responsibility of the Arkansas Department of Health (ADH) and our state's public water supply systems. Your local water supply system is responsible for taking required water samples, according to a schedule established by ADH. The Division of Public Health Laboratories at the ADH test the water samples for a broad variety of possible contaminants. When it comes to complying with the testing requirements of the Safe Drinking Water Act, Arkansas' water systems have one of the best records in the nation.
