Lead Water Service Line Information

Lead contamination in drinking water in other US cities has drawn attention to the potential public health risk of lead exposure from drinking water.  The City of Bowling Green is aware of these issues and takes special precautions to ensure lead contamination is not a problem for our water customers.      

There is no lead present in the drinking water as it leaves the Bowling Green Water Treatment Plant.  The City specifically treats the water to reduce the potential for lead to contaminate the drinking water.  The Ohio EPA requires the City to operate the Water Treatment Plant to meet Optimal Corrosion Control Parameter requirements which include adding orthophosphate to the water as a corrosion inhibitor.  Customers can view the Consumer Confidence Report (CCR) for information on lead sampling reported to the Ohio EPA.  


Potential sources of lead inside the customer’s residence could be lead pipes, lead solder, or lead in plumbing fixtures.  The US EPA banned lead pipes, lead solder, and lead fixtures after June 1986.  The regulations were updated in 1996, 2011, 2013, and 2020.  

Another potential source of lead is the water service line pipe that delivers water from the City water main to the customer's residence.  Different materials have been used for water service line pipes such as lead, galvanized iron, copper, or plastic - Click here for more information.  In Bowling Green, only copper or plastic has been allowed to be used for water service line pipe material since 1967.     

Ohio EPA has required all water suppliers, including Bowling Green, to provide information to customers on the water service line material used to serve the customer.  The water service line is the pipe that delivers water from the City's water main to the customer’s residence.  We have created a map to inform customers of the water service line material that serves their property.

The City of Bowling Green is responsible to maintain the water service line from the City water main to the Curb Stop (valve).  Typically, the curb stop is located near the curb, sidewalk, or right-of-way line at your property.  Several years ago, the City of Bowling Green replaced all known lead service lines that were the City’s responsibility.  There are some City water service lines where the pipe material is unknown and we are working to identify the pipe materials for every customer.   

The property owner is responsible to maintain the water service line from the Curb Box (valve) to the building.  The owner can identify their service line pipe material by inspecting the pipe where the water first comes into the building.  Typically, the water meter will also be located very close to this point.  CLICK HERE for example pictures that may help you determine the pipe material that serves your building.  If you are unsure about the pipe material serving your residence, please contact the Water Distribution Division at 419-354-3277 or your plumber.
