LANSING. MICH.  The Michigan Department of Environmental Quality (MDEQ) today provided an update on the citywide water testing efforts currently underway throughout Flint.

Residential Water Testing Efforts

Since Nov. 3, CORE (Community Outreach and Resident Education) team members have made multiple visits to homes where a water test hasn’t been submitted to encourage residents to have their water tested for free.  Teams made over 7,300 contacts and provided over 5,200 water testing kits, with some residents passing on the opportunity to get their water tested. 

In addition to the residential water testing effort, CORE members have completed over 441,000 visits at Flint homes and had over 138,000 conversations with residents to make sure they are properly installing and maintaining their filters and aware of available resources. 

Water Testing Efforts at Schools, Day Care and Elder Care Facilities

Since early-November, state teams have conducted flushing and testing at 63 of the approximate 78 facilities.  Of the 818 samples collected, 806 (98.5 percent) of them were at or below the 15 part per billion (ppb) federal Lead and Copper Rule (LCR) action level.  Further, of the 818 samples collected, 777 (95 percent) of them met the bottled water standard of 5ppb and lead was not detected in 662 (80.9 percent) of the samples collected.  MDEQ will work closely with any facility that had an exceedance. Water samples collected were unfiltered at all locations where it was possible to bypass the filter.   

State officials have previously conducted extensive flushing and testing, replaced fixtures and installed over 1,400 filters in schools, day care and elder care facilities.

Lead and Copper Rule (LCR) 6-month monitoring

The Flint water system has tested well below the 15ppb action level of the federal Lead and Copper Rule for over a year and a half.  The most recent 90th percentile lead value for the 6-month compliance period between Jan. 1, 2017, and June 30, 2017, was 7 ppb.  This included homes that have a lead service line or meet other criteria that make it an eligible location to determine compliance with the federal LCR.  The 90th percentile lead value for the previous 6-month compliance period between July 1, 2016, and Dec. 31, 2016, was 12 PPB.  The next 6-month monitoring period ends Dec. 31, 2017, and is expected to, again, test well below federal standards.  Results will be provided in mid-January after the data is reviewed and finalized.

Testing has also shown that service line replacement is an important component to the future long-term integrity of the Flint water system.  The last round of CLEAR (Confirming Lead Elimination After Replacement) testing data shows that 100 percent of the samples collected were below the 15 ppb federal action level after service line replacement was completed.  Service lines have been replaced at over 6,247 residences, to date.

While data supports that the use of water filters becomes a matter of personal choice after service line replacement, out of an abundance of caution, residents are reminded to use filters for six months after service lines are replaced to ensure protection against possible particulate releases due to physical disruptions caused during the service line replacement.
