Lead Service Lines in Frederick County, Maryland
Frederick County's water system serves approximately 74,911 people. Like many water utilities across the US, the county is required to inventory and report on lead service lines — the pipes that connect homes to the main water line underground.
What is a lead service line?
A lead service line is a pipe made of lead or lead-containing solder that delivers water from the street main into your home. Lead is a serious health concern, especially for young children and pregnant people. Even small amounts of lead in drinking water can cause lasting harm. If your home was built before the 1980s, or if you're unsure about your service line, testing is worthwhile.
Frederick County's inventory status
As of now, Frederick County has not yet completed a comprehensive inventory of lead service lines in its system. The utility is still in the process of documenting which homes have lead, galvanized steel (which can corrode and leach lead), or other pipe materials.
This doesn't mean lead isn't present in the system—it means the county is still working through the data collection phase, which is required under federal safe drinking water rules. Many utilities across the country are at similar stages.
What you can do now
Get your service line checked: You don't have to wait for the utility's full inventory. Contact Frederick County's water department directly and ask:
- What material is your service line made of?
- Has your home's water been tested for lead?
- What are your options for testing or replacement?
Test your water at home: An affordable lead test kit can tell you whether lead is currently in your tap water. This is the most direct answer, regardless of pipe material.
Reduce risk while you investigate: Run your tap for 30 seconds before drinking or cooking. Use cold water for cooking and drinking (hot water dissolves lead faster). These are simple steps with no downside.

Frequently asked
Is Frederick County water safe to drink?
The utility regularly tests water for safety, but if lead is entering your home through lead service lines, home-level testing is the most reliable way to know if it's in your tap water. Contact the county water department or test your own water.
How do I know if I have a lead service line?
Call Frederick County's water utility and ask about your service line material, or have a plumber inspect the pipe where it enters your home. The utility may also provide this information if you request it.
Can lead service lines be fixed?
Yes. The only permanent solution is to replace the service line with copper, plastic, or other non-lead material. Costs and assistance programs vary; ask your water utility about replacement programs or local rebates.
Is my child at risk from lead in water?
Young children are especially vulnerable to lead's effects. If you're concerned about health impacts, talk to your pediatrician or contact the CDC for guidance. Start by testing your water to know whether lead is present.
