IMPORTANT INFORMATION ABOUT LEAD IN YOUR DRINKING WATER
Providence Water found elevated levels of lead in drinking water in some homes/buildings. Lead can cause serious health problems, especially for pregnant women and young children. Please read this information closely to see what you can do to reduce lead in your drinking water.
Health Effects of Lead
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.
Where We Stand
In the first half of 2020, Providence Water's 90th percentile level was 10 parts per billion (ppb), which is below the lead action limit of 15 ppb.
For individual lead and copper compliance testing results at a known address, please click here.
EPA's Lead and Copper Rule establishes action levels (AL) of 15 ug/L for lead and 1.3 mg/L for copper based on 90th percentile level of tap water samples. An AL exceedance is not a violation but can trigger other requirements that include water quality parameter (WQP) monitoring, corrosion control treatment (CCT), source water monitoring/treatment, public education, and lead service line replacement (LSLR).
|year||1st period||2nd period||Action Level||1st period||2nd period||Action Level|
1 Initial round of compliance sampling per US EPA's Lead & Copper Rule.
2 PW reduced to annual sampling as approved by RIDOH.
3 PW reduced to triennial sampling as approved by RIDOH.
4 Annual sampling required as a result of treatment change (slight decrease in pH and alkalinity) implemented in Sept. 2005.
5 PW implemented treatment change (increase in pH and alkalinity) and began unidirectional flushing program.
