Lead and Copper Information

Lead and Copper

Lead and copper are not naturally present in our water, and they are not detected in the tap water leaving the plant. However, as long as there are lead services and lead containing fixtures in our water system, there will often be traces of lead detected during testing at locations in the distribution system. In an effort to keep levels low, the water plant feeds phosphoric acid, a corrosion inhibitor. This forms a protective coating on service lines and plumbing that helps reduce water from dissolving metals into the drinking water.

The Bay Area Water System 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 for 30 seconds to 2 minutes before using water for drinking or cooking.

Each community served by the Bay County Department of Water and Sewer performs a round of lead and copper testing annually. Samples are collected from homes that are thought to have the highest chance of leeching lead based on service line material and interior plumbing. A certain number of samples are collected in each community based on population.

The EPA has set action levels for both lead and copper based on the 90th percentile. If a community exceeds an action level, they are basically required to ‘take action’ and work towards reducing the levels. The 90th percentile means that 90% of the samples collected are at or below that level. The lead action level is 15 Parts Per Billion (PPB), and the copper action level is 1.3 Parts Per Million (PPM).

The table below shows the most recent results available.  These samples were collected between June-September 2020. Samples in Hampton Township were collected between July 2020-December 2020.
