Short answer: No measured result is above a legal limit; lithium sits above a screening level. Austins Colony serves 9,987 residents.
Your water bill or annual water quality report names your actual supplier.
AUSTINS COLONY (EPA PWSID TX2270255) delivers groundwater to 9,987 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.
lead 2.16 µg/L, below the 15 µg/L action level
PFHxS 4.2 ng/L, below the 10 ng/L limit (+4 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 Hornsby Bend, PFAS were detected below their limits, and PFBA 5 ng/L and PFPeA 12 ng/L with no federal or state limit; the lead 90th-percentile result was 2.16 µg/L against the 15 µg/L action level. AUSTINS COLONY (PWSID TX2270255) has a Purity Score of 90/100 (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.
AUSTINS COLONY (PWS ID TX2270255) is the public water system on record for Hornsby Bend, Texas, serving about 9,987 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 (2025-06-23 to 2025-12-16), PFBS was detected at 5.9 ng/L, below the 2,000 ng/L EPA health advisory, PFHxA was detected at 3.7 ng/L, below the 400,000 ng/L state limit and PFHxS was detected at 4.2 ng/L, below the 10 ng/L federal limit. PFBA (5 ng/L) and PFPeA (12 ng/L) were also detected; they have no federal or state limit.
AUSTINS COLONY's most recent lead 90th-percentile result (2026) was 2.16 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 Hornsby Bend holds 31 findings: 1 above a reference, 4 detected within the reference, 2 detected with no limit and 24 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
