In Roswell, the most likely source of trace amounts of lead would be from private home plumbing systems, including the service line from the meter to the home and internal plumbing. Roswell’s Water Utility’s corrosion control protocol minimizes the potential for these metals to leach into drinking water.
- Homes built prior to 1970 have a greater chance of having partial lead plumbing or galvanized lines that may have coatings containing lead.
- Many homes built prior to the late 1980s may have lead solder connecting copper pipes.
- Homes built after 1985 have significantly less potential for the presence of lead.
- Newer homes with brass fixtures installed before 2015 could contain minute amounts of lead.
