Lead and Copper testing
Providing safe, clean drinking water to our customers is of primary importance to the City of Livonia. The City continues to maintain water service with overall lead and copper concentration levels below the “Action Level” identified in the Michigan Safe Drinking Water Act, as revised in June 2018. Those revisions were adopted to better protect public health by enacting new water sampling rules and requiring communities with lead service lines and older housing stock to do more sampling. This new sampling method is expected to result in higher lead results, not because the water source or quality for residents has changed, but rather, because the revised Act has more stringent sampling procedures and analyses.
Since 1992, and in accordance with the Act, the City of Livonia has been conducting testing for lead and copper at sampling locations throughout the City. Testing in Livonia has consistently reported concentrations below the “Action Levels” identified in the Act. The State mandates that 30 homes in the City be tested. Those tests were completed in the summer of 2018, with tests from only one house reporting results higher than the “Action Level” of 15 parts per billion (ppb). That homeowner was provided educational information, as provided in the Act. Michigan’s Department of Environment, Great Lakes, and Energy (EGLE) evaluates each community’s compliance with the “Action Level” based on the 90th percentile of lead and copper results collected in that community’s sampling. The 90th percentile for the Livonia’s water supply was 8.89 ppb. Communities with a 90th percentile above 15 ppb of lead reach an “Action Level” that triggers increased water monitoring, educational outreach to customers and other efforts.
