It connects to the city’s network of water mains.  \nService lines can be made of materials, such as plastic or copper. But some of these pipes may also be made with lead or galvanized metal.  \nOur treatment protects water against corrosion.  \n“Corrosion” is when small amounts of metal dissolve from plumbing into water over time. It’s important to know that dissolved lead isnot visible.  \nThe good news? Our treatment keeps water safe to drink. We add Zinc Orthophosphate during treatment. This forms a protective coating inside pipes. It reduces risk of exposure to lead from plumbing.  \nService line with no corrosion  \ncontrol  \nService line with successful corrosion control  \nWe continuously test to make sure this process works.

We’re experiencing an increase in requests. We appreciate your patience!  \nHealth effects of lead  \nThere is no safe level of exposure. Exposure to lead in drinking water can cause serious health effects in all age groups. Infants and children can have decreases in IQ and attention span. Lead exposure can lead to new learning and behavior problems or exacerbate existing learning and behavior problems. The children of women who are exposed to lead before or during pregnancy can have an increased risk of these adverse health effects. Adults can have increased risks of heart disease, high blood pressure, kidney, or nervous system problems.  \n􀁨 Learn more about the health effects of lead: [www.epa.gov/lead](www.epa.gov/lead)  \nPhiladelphia’s Department of Public Health recommends parents and caregivers of young children (ages one to six) should request a blood lead test from their doctor.  \n Boiling water does NOT remove lead!  \n [Learn more:](Learn more: water.phila.gov/lead)[ water.phila.gov/lead](Learn more: water.phila.gov/lead)  \nVer al reverso en español 􀁨  \npage 2  \n10/2025  \nTranslation available: Español  \n國語  \nTiếng Việt  \nPусский  \n􀇫􀇳􀄣􀂡􀇓រ  \n廣東話  \nPortuguês  \nItaliano  \nFrançais  \n한국인  \n (215) 685-6300  \nLead Plumbing & Water Quality   \nService line materials & map  \nWater service lines are generally made from these four materials Newer service lines are made of a non-lead material, like copper or plastic.  \nSome older homes may have lead or galvanized metal in part of their service line.  \nNON-LEAD:  \nPlastic: Typically a less expensive option. It isnot associated with increased risk of lead.  \nNON-LEAD:  \nCopper: Copper service lines are considered safe because they are not associated with increased health risks.  \nToday, copper is used in most service line replacements.  \nLead: Used in the past because it is soft and can be bent. Lead can dissolve into water.  \nLead service line installation decreased after the 1950sas harmful health effects became clear.  \nGalvanized metal:  \nGalvanized steel or iron pipes can corrode. Over decades, any lead from a property’s plumbing can accumulate on the corroded walls of galvanized pipes.  \nService Line Material Map  \nOld lead service lines are a challenge across the country.
