Your water bill or annual water quality report names your actual supplier.
CAMP PENDLETON (SOUTH) (EPA PWSID CA3710702) delivers groundwater to 44,555 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.
2health-based violations in the last 10 years
From EPA SDWIS. Counted once per contaminant per year, as in the Track record score.
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.
Every filing is listed; the Track record score counts at most one per contaminant per year.

Plumbing inside a home can add lead that the system record can't show. A tap test tells you what reaches your glass.
lead 0.51 µg/L, below the 15 µg/L action level
PFHxS 5.4 ng/L, below the 10 ng/L limit (+1 more PFAS detected)
Screening tells you if something is worth a closer look; a lab result is the number you can act on.

Screening: quick check, not lab-grade
Safe Home (EnviroTestKits)
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
ETR Laboratories
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 Camp Pendleton South, PFAS were detected below their limits; the lead 90th-percentile result was 0.51 µg/L against the 15 µg/L action level. CAMP PENDLETON (SOUTH) (PWSID CA3710702) has a Purity Score of 88/100 (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.
CAMP PENDLETON (SOUTH) (PWS ID CA3710702) is the public water system on record for Camp Pendleton South, California, serving about 44,555 people. Confirm the utility on your water bill before acting on a specific finding.
Groundwater (primary source of record in EPA SDWIS).
In EPA's UCMR 5 testing (2024-02-14 to 2024-08-21), PFBS was detected at 3.2 ng/L, below the 2,000 ng/L EPA health advisory and PFHxS was detected at 5.4 ng/L, below the 10 ng/L federal limit.
CAMP PENDLETON (SOUTH)'s most recent lead 90th-percentile result (2023–2025) was 0.51 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 Camp Pendleton South holds 31 findings: 1 above a reference, 3 detected within the reference and 27 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
