Perfluorooctanoic acid
7.4ng/L
Each block = 4.0 ng/L federal MCL (2024)
Short answer: PFOA is above its federal limit (a 2024 limit that water systems have until at least 2029 to meet); lithium sits above a screening level. Alamogordo Domestic Water System serves 35,301 residents.
EPA lists this system for the city. Your water bill or annual water quality report names your actual supplier.

The bar is drawn in blocks of the 4.0 ng/L federal MCL (2024), so the length shows how far above it the result sits.

ALAMOGORDO DOMESTIC WATER SYSTEM (EPA PWSID NM3513319) delivers surface water to 35,301 residents. This report reflects 29 individual PFAS result(s) from the source UCMR5 observations and the latest Lead & Copper Rule 90th-percentile result. Water hardness and disinfectant type are pending the utility's own annual report.
0health-based violations in the last 10 years
From EPA SDWIS. A clean violation history means no enforcement action was recorded; it does not cover contaminants without a limit.
No result is not a pass. Your utility's annual water quality report may list them, and a certified lab test covers your own tap.
Plumbing inside a home can add lead that the system record can't show. A tap test tells you what reaches your glass.
PFOA 7.4 ng/L, above the 4 ng/L limit
lead 2 µg/L, below the 15 µg/L action level
Screening tells you if something is worth a closer look; a lab result is the number you can act on.

Lead, read as one of three ranges: 0–4, 5–15 or 15+ ppb
What it can't tell you: It shows a lead range, not an exact level, and tests nothing else unless you pay extra for the optional lab test.
Lab-certified results

50+ substances, including lead, copper, arsenic, nitrate, hardness and coliform bacteria
What it can't tell you: It does not test PFAS, and not every result on the panel falls under the lab's accredited scope.

PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Alamogordo, PFOA 7.4 ng/L was measured above the 4 ng/L federal limit in EPA's 2024 testing; the lead 90th-percentile result was 2 µg/L against the 15 µg/L action level. ALAMOGORDO DOMESTIC WATER SYSTEM (PWSID NM3513319) has a Purity Score of 58/100 (confidence: moderate), assessed at the water-system level and computed only from contaminants that were measured. Water can change in your own pipes, so a certified test is the only way to know what comes out of your tap.
ALAMOGORDO DOMESTIC WATER SYSTEM (PWS ID NM3513319) is the public water system on record for Alamogordo, New Mexico, serving about 35,301 people. Confirm the utility on your water bill before acting on a specific finding.
Surface water (primary source of record in EPA SDWIS).
Yes. In EPA's UCMR 5 testing (2023-11-06 to 2024-09-04), PFOA was measured at 7.4 ng/L against a 4 ng/L federal limit. Reverse osmosis and filters certified to NSF/ANSI 53 for PFOA/PFOS reduce them at the tap.
ALAMOGORDO DOMESTIC WATER SYSTEM's most recent lead 90th-percentile result (2022–2024) was 2 µg/L, below the 15 µg/L action level. That figure comes from sampled homes; lead usually enters from a building's own pipes and fixtures, so only a test at your tap tells you what you drink.
PurityMap's current record for Alamogordo holds 31 findings: 2 above a reference, 1 detected within the reference and 28 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
