Lead is rarely found in Portland’s source waters, and there are no known lead service lines in the distribution system. The main source of lead in water in the Portland area is household plumbing. Lead solder was commonly used in homes built or plumbed with copper pipes before 1985. Lead can also be found in brass plumbing fixtures and components.
When corrosive water stands in plumbing systems that contain lead for several hours or more, the lead may dissolve into drinking water. Water that has been sitting in household pipes that contain lead for several hours, such as in the morning or after returning from work or school, is most likely to contain lead.
In Portland, the most common source of lead exposure is not from lead in water but from lead-based paint. Other sources of lead include: household dust, soil, and other household objects such as toys, cosmetics and pottery. For more information on all source of lead, contact the LeadLine, 503-988-4000 or leadline.org.
Lead can cause serious health problems if too much enters your body from drinking water or other sources. It can cause damage to the brain and kidneys, and can interfere with the production of red blood cells that carry oxygen to all parts of your body.
The greatest risk of lead exposure is to infants, young children, and pregnant women. Scientists have linked the effects of lead on the brain with lowered IQ in children. Adults with kidney problems and high blood pressure can be affected by low levels of lead more than healthy adults. Lead is stored in the bones, and it can be released later in life. During pregnancy, the child receives lead from the mother’s bones, which may affect brain development.
The Portland Water Bureau treats the water with sodium hydroxide to raise the pH and reduce the corrosivity of water, provides resources for the reduction of lead exposure from all sources and provides free lead-in-water testing to customers.
