Flint, Michigan has asked for more time to complete federally required water testing of homes with lead service lines or lead indoor plumbing.
Flint is having issues finding enough homes that have lead service lines or lead indoor plumbing to complete federally required water testing, according to Booth Michigan.
The city needs 60 samples from confirmed tier 1 sites, but had just 43 confirmed as of Dec. 27, according to a letter from Robert Bincsik, director of the city’s Department of Public Works and Utilities.
“At this time we don’t know how many tier 1 addresses remain in the water system, the city will need to continue to work together with the Michigan Department of Environment, Great Lakes & Energy to develop a sampling plan that takes into consideration some points of concern we believe are valid and will require some conversations between the city of Flint and EGLE," said Bincsik.
Water samples were due to the state by Dec. 31. City workers were still collecting water on this date in an effort to comply with regulations, reported Booth Michigan. Most but not all lead service lines in Flint have been replaced during the last three years.
Federal regulations allow Flint to collect water samples from tier 2 sites if there are not enough tier 1 sites available, according to the U.S. EPA.
In its most recent completed testing, the city met the requirement of obtaining samples from at least 60 homes at higher risk of having elevated lead levels. Flint missed the deadline for providing documentation to verify the samples came from tier 1 homes, however, reported Booth Michigan.
