Garden City — More than a quarter of the 31 sites with "known" lead service water lines in this Wayne County suburb were found to have exceeded the state's "action level" for lead, 15 parts per billion, the city says.

Eight sites tested above action levels in samples taken in August and September, according to a statement Saturday from Garden City. 

The city explains that action levels are not a "health-based standard," but do trigger increased sampling and educational outreach, among other tactics.

Garden City offered a number of tips for consumers to reduce their potential lead exposure, including letting water run a bit before using it to drink or brew coffee.

Boiling water, though, does not reduce lead levels.

The city advises people who do not have lead service lines to let water run for 30 seconds to two minutes, while those with lead service lines should let water run for five minutes before use.

Garden City said it will soon "provide a comprehensive public education document" on the matter, and will be collecting 60 samples every six months to determine what, if any, corrective actions are needed.

The city council and the mayor's office support replacement of all known lead lines in the city, the statement said, but offered no timetable. The mayor's office could not immediately be reached for comment. 

According to the website for Michigan's Lead and Copper Rule: water suppliers are required to replace an average of 5 percent of their lead service lines every year for the next 20 years unless an alternate schedule is approved by the state environmental department.

Filters are available free for "households with a child," pregnant women or anyone who can't afford one. Those will be offered from 2-6 p.m. on Thursday and Friday at the Maplewood Community Center, 31735 Maplewood.
