MGM National Harbor Lead Service Line Inventory

What you need to know

MGM National Harbor serves about 24,000 people in Maryland. Like all US water utilities, it is required by federal law to inventory lead service lines—the pipes that carry water from the main water line under the street to homes.

The current status: MGM National Harbor has not yet completed a public inventory of lead service lines. This means the utility has not published a count of how many lead pipes exist in its system, or which neighborhoods are affected.

This is not unusual. Many utilities across the country are still working through their inventories. Federal rules require all utilities to complete this work by October 2024, with results made public by October 2025.

What a lead service line means for your home

A lead service line is a direct path for lead to enter your drinking water. Lead is a toxic metal that poses real health risks, especially for young children and pregnant people. Water sitting in these pipes overnight or over the weekend can accumulate higher lead levels.

The good news: lead in water is preventable. Flushing your pipes, using a filter certified for lead reduction, or replacing the service line all work—and some utilities offer cost assistance.

What MGM National Harbor should tell you

Contact the utility directly to ask:

• Does your specific address have a lead service line?
• What is the utility's timeline for completing its full inventory?
• Are there water quality testing programs available to customers?
• Does the utility offer any financial assistance for service line replacement?

MGM National Harbor's customer service team can answer these questions and provide guidance based on your home's age and location.

How to protect yourself now

Until you know your service line status, assume it might contain lead. This is not alarmist—it's practical. Simple steps reduce exposure:

• Flush cold water for 30 seconds to 2 minutes before drinking or cooking.
• Use a filter certified by NSF or WQA for lead reduction.
• Test your water through your state lab or a certified private lab ($20–50).

If you have young children or are pregnant, contact your pediatrician or OB-GYN for guidance on water testing and use.

Next steps for residents

• Contact MGM National Harbor to ask if your address has a known lead service line, and request information about their inventory completion timeline.
• Test your water if you're concerned; results help you make informed decisions about filtration or replacement.
• Flush and filter now while you wait for your utility's inventory—these are free or low-cost and reduce lead exposure immediately.
• Check your state's lead service line webpage for Maryland-specific resources, testing labs, and replacement assistance programs.
