Lead Lines Mapping

Ohio EPA received maps from all 1,851 water systems in Ohio. Updated maps are posted as they are received.

Under a new Ohio law enacted in June 2016, community and nontransient noncommunity public water systems are required to identify areas that are known to contain or likely to contain lead service lines by March 9, 2017. The law requires community water systems to identify and map areas of their distribution systems that are known or likely to contain lead service lines. These systems also are required to identify and provide a description of the characteristics of buildings served by the system that may contain lead solder, fixtures or pipes. Single building community and nontransient noncommunity water systems are required to map areas of the system that have solder, fixtures and pipes containing lead. The maps will be used by Ohio EPA to ensure that the proper lead and copper sampling is done in areas of lead service lines.
