Short answer: No measured result is above a legal limit; lithium sits above a screening level. Hooper Water Improvement District serves 20,820 residents.
Your water bill or annual water quality report names your actual supplier.
HOOPER WATER IMPROVEMENT DISTRICT (EPA PWSID UTAH29006) delivers groundwater to 20,820 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.
1health-based violation 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 3.3 µg/L, below the 15 µg/L action level
Lithium 19.5 µg/L, above the 10.0 µg/L EPA health reference level
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 Hooper, no regulated PFAS were detected in EPA's 2024 testing; the lead 90th-percentile result was 3.3 µg/L against the 15 µg/L action level. HOOPER WATER IMPROVEMENT DISTRICT (PWSID UTAH29006) has a Purity Score of 95/100 (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.
HOOPER WATER IMPROVEMENT DISTRICT (PWS ID UTAH29006) is the public water system on record for Hooper, Utah, serving about 20,820 people. Confirm the utility on your water bill before acting on a specific finding.
Groundwater (primary source of record in EPA SDWIS).
None of the 29 PFAS in EPA's UCMR 5 testing (2023-09-11 to 2024-03-12) was detected. "Not detected" means below the lab's reporting limit, not proven zero.
HOOPER WATER IMPROVEMENT DISTRICT's most recent lead 90th-percentile result (2022–2024) was 3.3 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 Hooper holds 31 findings: 1 above a reference, 1 detected within the reference and 29 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
