12 12 Do you have a private side lead service line (LSL)? It is very likely that your private side service line is made of lead if: the public side service line is lead and/or your house was built before 1945.

13 13 Lead Service Identification Providence Water has a record of all public side lead services. Check our online Lead Service Location Map for your address Water Main Rehabilitation Hotline

14 14 Lead Service Identification

15 15 Lead Service Identification LEAD PIPE If the scraped area is shiny and silver, your service line is lead. COPPER PIPE If the scraped area is copper in color, like a penny, your service line is copper.

16 16 Marieville Service Replacements Less than 6% of the Public Side services in this project are made of lead. According to PW records, there are only 29 public side lead services (out of over 500 total services) in the construction area. These 29 public side lead services will be replaced from the water main to the curb stop as part of this project. 94% of the Public Side services in this project are already copper from the main to the curb stop.

32 32 Why is lead a concern? Lead can cause serious health problems if too much enters your body from drinking water or other sources (lead paint, dust). Highest Risk: Infants and small children Pregnant women Adults with kidney problems Adults with high blood pressure

33 33 How does lead get into my drinking water? Drinking water that leaves our water treatment plant in Scituate and journeys through PW s distribution system is lead free.

34 34 How does lead get into my drinking water? When water comes in contact with sources of lead for an extended time period, lead can leach into the water: Lead service lines Lead based solder Lead pipe (within household) Brass and chrome plated fixtures/faucets Brass valves

35 35 How does lead get into my drinking water?

36 36 How does lead get into my drinking water?

37 37 What can you expect after construction? Temporary increase in lead levels at the tap. If you do not replace your private side LSL, it will continue to contribute lead to your tap. Full replacement does not guarantee zero lead levels.

38 38 What do you need to do after construction? Flush your interior plumbing Complete lead sample test after lead service replacement

39 39 How can you reduce lead at your tap? Use water pitcher and filters provided to you by PW for 6 months after construction when using water for cooking and drinking. Filters are certified to reduce lead (NSF 53 certified).

40 40 Tips to Reduce Lead Replace your private side lead service connection. Flush your pipes Run the cold water faucets in your home until the temperature of the water gets noticeably colder and then for another minute (usually at least 3 5 minutes in all). Use only cold water for cooking and drinking. Periodically remove the faucet aerators and flush the screen section of all debris. Replace internal plumbing lead based soldered pipes, brass/chrome plated faucets that may contain lead.
