Everyone deserves high quality drinking water, whether you rely on a public or private water supply. A public water supply connects many people to the same drinking water system, which collects water from rivers, reservoirs, springs, or ground water. However, some public water systems may have problems associated with the drinking water treatment or distribution systems These water quality problems must be reported to consumers. If you have questions or concerns about your public drinking water supply, contact your local water purveyor and request a copy of their latest test results, which they are required by law to provide to their customers.
