LOS ALAMOS MUNICIPAL WATER SYSTEM Lead Service Line Inventory
LOS ALAMOS MUNICIPAL WATER SYSTEM serves about 25,000 people in New Mexico. Like many water systems across the country, it is required by the EPA to identify and report on lead service lines—the pipes that connect the water main to individual homes.
What we know about lead service lines in Los Alamos
Lead service lines pose a real risk: when water sits in these pipes or the pipes corrode, lead can leach into drinking water. This is especially concerning for infants, young children, and pregnant people.
Current inventory status: As of our last update, the water system has not yet reported completing a full lead service line inventory to the EPA. This doesn't necessarily mean lead lines aren't present—it means the system is still in the process of identifying which homes may have them. Some utilities take several years to complete this work.
Why this matters for your home
If you live in the Los Alamos area and your home was built before 1986, there's a higher statistical chance your service line could contain lead. Homes built in the 1970s or earlier are at greatest risk.
You won't know if your service line is lead without testing or checking your utility's records. Even if you have a lead service line, you can take steps to reduce exposure—like using a filter certified for lead removal or running the tap before drinking.
Getting answers about your specific home
Your first step is to contact LOS ALAMOS MUNICIPAL WATER SYSTEM directly. Ask them:
- Do they have records showing whether your service line is lead or non-lead?
- When will their full inventory be complete?
- What free or low-cost testing programs are available?
The utility should be able to tell you based on your address, the age of your home, or historical plumbing records. Some systems also offer free lead testing kits to residents.
Next steps for residents
- Contact the water utility with your service address and ask about your service line material.
- Have your water tested if you're concerned; many health departments offer this at low or no cost.
- Consider a filter certified for lead removal (NSF/ANSI Standard 53) if you're waiting for results or answers.
- Talk to your pediatrician or local health department if you have questions about health impacts, especially for young children.
