Lead and Copper Rule Sampling program

Lead and Copper Rule (LCR) Monitoring Program


The Navy is committed to ensuring safe drinking water for all who work, train and live on its installations.  As a result of drinking water regulations administered by EPA which are also adopted by states, the Naval Facilities Engineering Command Mid-Atlantic periodically monitors all Navy Public Water Systems (PWS) for lead and copper.  PWS that demonstrate consistent results below EPA action levels are required to monitor every 3 years.  PWS that exceed EPA action levels must monitor more frequently.

The LCR evaluates the most critical condition of lead exposure in drinking water. When water stands in lead pipes, lead plumbing systems or lead fixtures for several hours, the lead may “leach” or dissolve into the drinking water.  This means that the first water drawn from your tap in the morning, or later in the afternoon after returning from work or school, can contain elevated levels of lead.  For this reason, EPA requires a statement in the annual Consumer Confidence Report that recommends consumers to flush their tap for 30 seconds to 2 minutes after water has been sitting for several hours.

Under the authority of the Safe Drinking Water Act, the Environmental Protection Agency (EPA) set the Action Level (AL) for lead in drinking water at 15 parts per billion (ppb), and the AL for copper in drinking water at 1300 ppb.  This means utilities must ensure that water from the customer’s tap does not exceed this level in at least 90 percent of the homes sampled 90th percentile value. The AL is the concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow.

Since corrosive water can cause lead to leach from plumbing materials that contain lead, our Navy-owned water treatment plants and city water suppliers strive to keep the corrosivity of our water as low as possible.  Additionally, there are actions you can take to reduce your exposure.  We strongly recommend consumers to review below LCR General Information and Facts link and take the steps listed to reduce your exposure to lead in drinking water. 

Military and civilian personnel are encouraged to contact their command leadership or their health care provider if they have individual questions or would like assistance in understanding and interpreting the results.  If you have any health questions or concerns, we encourage you to call your health care provider.
