MEMPHIS, Tenn. — After examining its archives, MLGW found records of 38,275 water service lines that were possibly made of lead, out of the total 288,000 water service lines listed in that database.

MLGW previously estimated there were up to 30,000 potentially lead pipes.

Regardless, MLGW affirmed there is no evidence of lead poisoning from its water, stating its corrosion control process. MLGW water has consistently met EPA drinking water standards, the utility company said.

According to MLGW, the potential lead pipes recorded in the database were installed between 1874 and 1940 and are mostly within the Parkways, which contain the oldest areas of the city.

MLGW noted this database, which is 16 years old, does have some inaccuracies, so the 38,275 number may not reflect the true number of potential lead pipes. For example, MLGW said some of the lines could have been replaced by now or are no longer connected to homes.

MLGW is working to verify its records and investigate the pipes further. The utility company will post a list of possible lead service lines next week, and inspections of the pipes are expected to be completed by 2020.
