Newark Revamps Corrosion Control Strategy for Water Service Lines

摘要

The city of Newark, New Jersey, USA, is introducing a new corrosion control treatment program and working to replace lead service lines on private property after tests have repeatedly showed elevated lead levels in drinking water. In 2017, Newark first reported lead levels above 15 ppb, which is the regulatory limit set by the U.S. Environmental Protection Agency's (EPA) (Washington, DC, USA) Lead and Copper Rule.According to the city, the majority of Newark households are not impacted because they receive water from the Wanaque water system, where tests show the corrosion control of orthophosphate is effective. In addition, service lines in homes built after 1986 do not contain lead due to a U.S. federal ban on lead pipes, and in 1953, the city stopped allowing new construction projects to include lead service lines and plumbing. Moreover, larger facilities, such as office buildings, apartments, hotels, and hospitals, are unlikely to have lead service lines because ductile and cast iron, rather than lead pipes, were utilized in that type of construction.
