Lead Service Line Inspections

Service Line Inspections

The Environmental Protection Agency (EPA) recently mandated public water systems to identify water service line materials as part of the EPA's Lead and Copper Rule. By October 2024, public water systems are required to develop an inventory of water service line material types for properties within their service territory. 

Like many communities, the City of Troy utilized lead for water service lines for public and private sides in the early 20th century. In 1944, the City enacted rules that banned the use of lead and required all new residential private and public services to be copper. To date, Troy has evaluated the public side of the water services and replaced all known lead and galvanized water lines. 

Based on the new EPA mandates, the City of Troy estimates 2,200 private side water service lines in Troy that must be identified. Residences built before February 1, 1944, will need to be inspected for lead.

City inspectors will need to access the location where the water service enters the residence. This connection is commonly in the basement area, crawlspace, or utility closet. Property owners will receive a letter in advance of City inspectors' visit.

Lead service inspections take approximately 15 minutes to complete.

If it is determined your water service line material is lead, additional information will be provided to you.

How can I know whether my home may have had lead lines?
This map was last updated in 2022 and assumes homes built prior to February 1, 1944 are lead until proven otherwise. Inspectors will be determining service lines at these addresses. 

Can I tell if my home has lead lines?
Lead testing kits are available at most hardware stores. If you would like to perform a test on the service line as it enters your home you can do so by following the instructions here.

Why replace my lead service pipe?
If you have a lead service pipe, you are at risk of lead exposure. Lead can be released when water comes in contact with pipes that contain lead. If present, elevated lead levels can cause serious health problems, especially for pregnant women and young children. Lead service pipes are replaced with copper pipes.

How does Troy prevent lead in its drinking water?
Lead is not present in our source water. Lead contamination in drinking water results from lead plumbing materials exposed to corrosive water. To prevent this, the Water Plant staff continuously monitors the treatment process to control alkalinity and pH, ensuring our product is in a non-corrosive and absolutely safe state.

For decades we have tightly controlled the chemistry of our water, utilizing common but very effective treatment techniques to achieve a precise Ohio EPA- mandated calcium carbonate stability index. This precise chemistry allows us to deposit a very thin protective layer of calcium carbonate coating within our system's piping and fixtures, to add an extra layer of protection from lead plumbing components that may exist in older sections of our system.

How often does Troy conduct lead testing?
By Ohio and US EPA mandate, we conduct both lead and copper testing at 30 locations every three years. Samples are taken by citizens in Troy residences and submitted to an EPA-approved independent laboratory for analysis.

What are the results of Troy lead testing?
Historically, Troy has shown very few detections for lead since testing began in 1993. The EPA Action Level of concern is set at 15 parts per billion. Public Water Systems exceeding this 15 ppb standard in more than 10% of their samples are required to take special measures to control water quality. Troy's sampling results have always been well below the level of concern.

Are there lead sources for drinking water in every Troy home built before 1944?
Lead sources and lead levels in water vary between buildings, so it is important to identify and remove all lead sources for each property. Some service pipes that connect the lead-free water main in the street to household plumbing contain lead. In addition, some plumbing fixtures and joint solder inside homes can contain lead.

I have a lead service line; what steps should I take to reduce exposure in my home?
The best step to take is to have all lead service lines removed as soon as possible. In the interim, there are steps you can take to reduce exposure to lead in your drinking water. The Ohio EPA provides more information here.
