Flint records lowest lead levels in drinking water since creation of stricter state standards
July 23, 2021
The Michigan Department of Environment, Great Lakes, and Energy (EGLE) yesterday announced that the City of Flint's water system has met state and federal standards for lead in drinking water for five years in a row.
EGLE Director Liesl Clark joined Flint Mayor Sheldon Neeley to announce the results.
"The people of Flint deserve safe, clean drinking water," she said. "I'd like to be the first to congratulate the mayor and city staff for reaching this important milestone. EGLE remains committed to protecting residents from lead exposure by working collaboratively with the city to reduce and ultimately eliminate sources of lead in their drinking water system."
Since July 2016, Flint's water system has tested below action levels of the federal Lead and Copper Rule (LCR) during 10 consecutive monitoring periods. The latest six-month monitoring period from Jan. 1 through June 30 shows that 90% of the samples collected are at 3 parts per billion (ppb) under the new, stricter state rule that requires a fifth liter sample to better reflect the impact of lead service lines.
The latest test results were calculated from drinking water samples drawn from 71 homes, apartment buildings, and businesses known to have lead service lines. Flint officials expect to have all the city's remaining lead service lines replaced before the end of the year.
Ongoing monitoring by EGLE and the City also confirm that other water quality measures like residual chlorine and ortho phosphate levels are being effectively managed.
Michigan in 2018 adopted the nation's toughest lead rules for drinking water. The state's Lead and Copper Rule (LCR) requires that all lead service lines in the state be removed. Water supplies are required to replace an average of 5% of their lead service lines every year for the next 20 years. Starting in 2025, the rule lowers the action level to 12 ppb.
