The city of Harper Woods, which conducts testing of tap water in homes for lead and copper yearly, collected water samples from 30 homes this past summer, which indicated high levels of lead.

The city of Hamtramck will distribute free water filters to residents on Thursday after routine tap water testing revealed substandard lead levels.

Unsatisfactory lead levels have been discovered in the tap water in the city of Wayne during routine testing, prompting the city to increase sampling at more locations.
