LOWER VALLEY WATER DISTRICT (EPA PWSID TX0710154) delivers surface water to 59,049 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.
19 lead service lines; 31 galvanized lines to replace
PFHxA 3.4 ng/L, below the 400000 ng/L state limit (+2 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 Socorro, PFAS were detected below their limits, and PFBA 5.3 ng/L and PFPeA 3.3 ng/L with no federal or state limit. LOWER VALLEY WATER DISTRICT (PWSID TX0710154) has a Purity Score of 100/100 (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.
LOWER VALLEY WATER DISTRICT (PWS ID TX0710154) is the public water system on record for Socorro, Texas, serving about 59,049 people. Confirm the utility on your water bill before acting on a specific finding.
Surface water (primary source of record in EPA SDWIS).
In EPA's UCMR 5 testing (2023-11-29 to 2024-05-29), PFHxA was detected at 3.4 ng/L, below the 400,000 ng/L state limit. PFBA (5.3 ng/L) and PFPeA (3.3 ng/L) were also detected; they have no federal or state limit.
Lead is not in Socorro's current published record. Lead usually enters from a building's own pipes and fixtures, so a certified home test is the way to know yours.
PurityMap's current record for Socorro holds 31 findings: 1 above a reference, 1 detected within the reference, 2 detected with no limit 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.
