Health Effects of Exposure to Lead in Drinking Water

Lead and Your Health

Lead is a powerful neurotoxin, which means exposure to lead can damage the brain. It can also injure other soft tissues and organs, can interfere with the formation of blood, and exposure to enough lead can even kill. Both children and adults are vulnerable to lead’s health effects.

Common Health Effects on Children:

  • Brain damage resulting in IQ loss, learning disabilities, hyperactivity, inability to concentrate, and/or behavior problems
  • Stunted growth
  • Hearing problems 

Common Health Effects on Adults:

  • Hypertension
  • Anemia
  • Reduced sperm count
  • Increased risk of miscarriages

Young children are most vulnerable to lead’s effects because prior to age six, their brain and central nervous system are still forming and easily susceptible to damage. For an adult to suffer significant health effects, exposure to lead would have to be sustained and more intense. Most adults who are affected by lead have been exposed in an occupational setting, such as working as a house painter or in a battery recycling plant.  

Pregnant women are at special risk, because the lead they absorb crosses the placenta and enters the fetus.  

It’s important to remember that there is no known safe level of lead in a human body. The US Centers for Disease Control and Prevention (CDC) has set a blood reference value at 3.5 micrograms of lead per deciliter of blood (µg/dL). This is why the District Department of Energy and Environment (DOEE) and DC Health established a special program that offers a visit to the home of families of children diagnosed with a blood lead level at 3.5 µg/dL or above. During this visit, trained staff provide education to the family about how to minimize the risk of exposure to lead, as well as some dust testing, to see whether lead-contaminated dust might be present in the home.

DC Water Breaks Ground on Piney Branch Tunnel, Final Phase of DC Clean Rivers Project

Today, DC Water broke ground on the Piney Branch Tunnel, the final major tunnel in our Clean Rivers Project. This work will help keep sewage and trash out of local waterways and make Rock Creek, the Potomac River, and the Chesapeake Bay cleaner for our community.

When we finish the Piney Branch Tunnel, it will hold at least 4.2 million gallons of rainwater and wastewater during heavy storms. Instead of overflowing into Piney Branch, that water will go to the Blue Plains Water Resource Recovery Facility, where it will be treated.
