Short answer: No measured result is above a legal limit; lithium sits above a screening level. Galveston County Wcid 1 serves 30,399 residents.
Your water bill or annual water quality report names your actual supplier.
GALVESTON COUNTY WCID 1 (EPA PWSID TX0840001) delivers surface water to 30,399 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 1.23 µg/L, below the 15 µg/L action level
PFBS 3.8 ng/L, below the 2000 ng/L EPA health advisory (+3 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 Dickinson, PFAS were detected below their limits, and PFBA 12.1 ng/L and PFPeA 157 ng/L with no federal or state limit; the lead 90th-percentile result was 1.23 µg/L against the 15 µg/L action level. GALVESTON COUNTY WCID 1 (PWSID TX0840001) has a Purity Score of 99/100 (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.
GALVESTON COUNTY WCID 1 (PWS ID TX0840001) is the public water system on record for Dickinson, Texas, serving about 30,399 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 (2023-01-17 to 2023-10-13), PFBS was detected at 3.8 ng/L, below the 2,000 ng/L EPA health advisory and PFHxA was detected at 5.4 ng/L, below the 400,000 ng/L state limit. PFBA (12.1 ng/L) and PFPeA (157 ng/L) were also detected; they have no federal or state limit.
GALVESTON COUNTY WCID 1's most recent lead 90th-percentile result (2024–2026) was 1.23 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 Dickinson holds 31 findings: 1 above a reference, 3 detected within the reference, 2 detected with no limit and 25 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
