All contaminant levels in your municipal water supply are within federal and state regulatory limits. The Water Quality Evaluation Table displays detailed test results. The City of Kennewick routinely tests for all regulated contaminants and several unregulated substances, though not all are included in this report. Additional monitoring data is available upon request.

Certain populations may be more vulnerable to water contaminants than others. Individuals with compromised immune systems—including cancer patients undergoing treatment, organ transplant recipients, those with HIV/AIDS, certain elderly individuals, and infants—may face higher risks from infections. These individuals should consult healthcare providers about their municipal water consumption. Guidelines from the EPA and CDC regarding protection from Cryptosporidium, Giardia and other microbial contaminants are available through the Safe Drinking Water Hotline (1-800-426-4791).

Elevated lead levels can pose serious health risks, particularly for pregnant women and young children. Lead typically enters drinking water through service lines and household plumbing materials, not from the municipal supply itself. While the City of Kennewick delivers high-quality water, we cannot control materials used in residential plumbing. To reduce potential lead exposure, consider running your tap for 30 seconds to 2 minutes before using water for drinking or cooking, especially after periods of non-use. For concerns about lead, consider water testing. Information about lead in water, testing methods, and exposure reduction is available from the Safe Drinking Water Hotline (1-800-426-4791) or at http://www.epa.gov/safewater/lead.
