Water Treatment

American Water’s treatment and delivery of water is an intricate and involved process. From the moment water begins the journey from its source through our highly sophisticated plants, into underground pipes, and to its final destination, our teams of professional scientists and plant operators oversee its passage. We closely monitor its movement and quality and test it frequently.

Each year, we conduct nearly one million tests and measurements using the most advanced technology and equipment available at our state-of-the-art, world-renowned research laboratory in Belleville, Illinois, and at our local utility labs. Our scientists test water samples from across the country to protect against viruses, microbes, hazardous chemicals, algae, metals, minerals, and other potential contaminants.
