Lead in Drinking Water
How To Reduce Lead In Your Drinking Water
How Do I Identify My Pipe Material
Tell Us Your Pipe Material
__________________________________________________
Did you know? The City of Newberg is required to sample for Lead and Copper in our water distribution system every 3 years.
Lead was a common service line material used in some parts of the country, but it has not been documented as an often-used material for water services in the Pacific Northwest. It was, however, used in plumbing fixtures which can leave traces of lead in drinking water.
In compliance with the Environmental Protection Agency (EPA) 2008 revision of the Lead and Copper Rule, the City’s Lead and Copper sampling sites consist of single-family structures with copper pipes with lead solder installed after 1982 (but before the effective date of Oregon’s lead ban which was 1985) or contain lead pipes and/or that are served by a lead service line. In 1986, Congress banned the use of lead material in plumbing but allowed existing pipes to remain in service.
Revised Lead and Copper Rule 2021
In December 2021, the EPA published the revised Lead and Copper Rule. A requirement of the updated rule is for water suppliers to create a public facing map of all service line and pipe materials within the city’s service area. The City of Newberg currently has over 7,200 water services in our distribution system. This is a heavy lift for City staff, and given our limited resources, we are asking the community to help us comply with the new rule. City staff are confident that there are no lead service lines in our service area. We need your help in documenting service lines and completing the map.
Please refer to our How to Identify Pipe Material section to help you determine what type of pipe material you have entering your house. The Interactive Links to Identifying Pipe Material section below lists interactive websites to help identify pipe materials. Once you have identified your pipe material, or if you already know your pipe material, please use the webform to submit the information to our Water Quality staff. If possible, please include three photographs of where your service line enters your house for staff to use in the case of a discrepancy. You can also send an email of your pipe material information and photographs to leadandcopper@newbergoregon.gov .
How Does Lead Get In My Water?
Water leaving the treatment plant and traveling through water mains is always free of lead. However, lead is sometimes present in lateral pipes connecting older homes to the water system, or in fixtures and home plumbing. Studies have shown that most lead in drinking water is the result of the corrosive action of water on home plumbing, and homes of a certain age are most susceptible. City of Newberg Water Treatment Plant adjusts the water’s chemistry at the treatment plant to minimize the possibility of lead dissolving into the water, but there are additional steps you can take at home. Sources of lead in home plumbing and fixtures include:
- Copper Pipe with Lead Solder
- Faucets and fixtures
- Galvanized Pipe
- Lead Goose Necks and Pigtails that connect your pipes to the water meter
Health Effects of Lead
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 increased risk of these adverse health effects. Adults can have increased risks of heart disease, high blood pressure, kidney, or nervous system problems. Click HERE for EPA’s website where you can read more about the health effects of lead.
What We Do To Protect Your Water
The City of Newberg owns and operates a "wellfield" where water is pumped from an underground aquifer located south of the Willamette River. This water source is part of the greater Chehalem Watershed. A natural system bringing rainwater from the surrounding hills to the underground aquifer. There are restrictions on how surrounding land is used to protect underground water integrity. 2 separate pipelines are used to transport the raw water to the treatment plant. This provides Newberg with 100% of its water supply. The "raw" water from the aquifer is safe to drink however, naturally occurring Iron and Manganese affects taste and color. The Water Treatment Plant filters the water and adds sodium hydroxide to raise the PH levels that prevents leaching of lead and copper from indoor plumbing.
The City is required to disinfect the water to ensure it remains safe while it travels through the System. Chlorine is added at 1 ppm to ensure that a minimum trace amount is distributed through out the system. The City continuously monitors the chlorine residual in the water leaving the water treatment plant and collects samples throughout the distribution system on a weekly basis. The City is also required to adjust the pH level of the water leaving the WTP to above 7.0 (neutral) so that the water is not corrosive to piping.
How To Reduce Lead In Your Drinking Water
There are steps you can take right away to reduce the possibility of lead in your water.
- Run the Tap Before Use – Lead levels are likely at their highest when water has been sitting in the pipe for several hours. Clear this water from your pipes by running the cold water for several minutes, which allows you to draw fresh water from the water main. Please remember to be water wise and try not to waste water. You can use this water on house plants or to flush toilets
- Clean Aerators – Aerators are small attachments at the tips of faucets which regulate the flow of water. They can collect small particles of lead in their screens. It’s a good idea to remove your aerators at least monthly and clean them out.
- Use Cold Water for Drinking and Cooking – Always cook and prepare baby formula with cold water, because hot water dissolves lead more quickly, resulting in higher levels in water.
- Change Out Old Fixtures - Plumbing regulations now stipulate that all fixtures must be manufactured lead-free. Consider installing new fixtures and/or pipes to eliminate sources of exposure.
- Filter the Water – Many home water filters are effective at removing lead. If you purchase a filter, make sure it is certified for lead removal and that you maintain it properly. Find out more on filter certification at https://www.nsf.org/testing/water/water-treatment/water-treatment-filtration-systems.
- Do Not Boil Water – Boiling water will not remove lead from the water.
How Do I Identify My Pipe Material?
Step 1 – Locating where the service line enters your house
This is typically found in the basement or crawl space and could also be located near the water heater or the washing machine. A shut off valve is installed on the pipe after the point of entry.
Identify a test area on the pipe between the point where it enters the building and the valve. If the pipe is covered or wrapped, expose a small area of metal.
Step 2 – Perform the scratch and magnet test
Scratch Test - Use a flat head screwdriver or a coin to perform a scratch test
Magnet Test - Use a refrigerator magnet to perform the magnet test
Step 3 – Identify the service line material
Each type of pipe will produce a different type of scratch, react differently to the magnet, and make a unique noise when tapped with your screwdriver or coin. Follow the instructions below to help you identify your service line material.
Copper or Brass
- Scratch Test - Scraped area is like a copper penny
- Magnet Test - Magnet will not stick
- Tap Test - Tapping sound is metallic and ringing
- Threads - No threads
- Copper pipes could be bluish in appearance
Galvanized Pipe
- Scratch Test - Scraped area remains dull silver or gray
- Magnet Test - Magnet will stick
- Tap Test - Tapping sound is metallic and ringing
- Threads - Has threads
Lead Pipe
- Scratch Test - Scrapes easily to shiny bright silver
- Magnet Test - Magnet will not stick
- Tap Test - Tapping sound is dull
- Threads - No threads
- Bulbous where connects to pipe or shutoff
Plastic Pipe
- Scratch Test - Scrape feels dull and not metallic
- Magnet Test - Magnet will not stick
- Tap Test - Tapping sound is dull like plastic
- Threads - No threads
- Could be any number of colors (white, red, blue, clear)
