    Purpose: To collect occurrence data for contaminants suspected to be present in drinking water but that do not have health-based Standards set under the Safe Drinking Water Act (SDWA).The Unregulated Contaminant Monitoring Program is the primary source of drinking water contaminant occurrence data used by USEPA in regulatory determinations.
Analysis frequency is every three years; thirty samples are collected from the distribution system
Infants and children who drink water containing lead in excess of the action level could experience delays in their physical or mental development. Children could show slight deficits in attention span and learning abilities. Adults who drink this water over many years could develop kidney problems or high blood pressure. If present, elevated levels of lead can cause serious health problems, especially for pregnant women and young children. Lead in drinking water is primarily from materials and components associated with service lines and home plumbing. The City of Salem Water Department is responsible for providing high quality drinking water, but cannot control the variety of materials used in plumbing components. When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing your tap 30 seconds to 2 minutes or until it becomes cold or reaches a steady temperature before using water for drinking or cooking. If you are concerned about lead in your water, you may wish to have your tested. Information on lead in drinking, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline or at http://ww.epa.gov./safewater/lead.
