The Michigan Department of Environment, Great Lakes, and Energy (EGLE) recently announced that the City of Flint’s water system has entered its sixth consecutive year of meeting state and federal standards for lead in drinking water.

Since July 2016, the city of Flint’s water system has tested below action levels of the federal Lead and Copper Rule (LCR) during 11 consecutive monitoring periods. The latest six-month monitoring period, from July 1 through Dec. 31 2021, find that the 90th percentile calculation for the city’s collected samples is at 7 parts per billion (ppb) for lead. The 90th percentile calculation of 7 ppb means 90 percent of the test results used in the calculation came in at or below 7 ppb.
