Gainesville Regional Utilities has a Water Score of 100 out of 100 (Strong) on our scale. 0 of 12 detected contaminants are above a published health guideline (2018-2025). EPA compliance: no open violations (July to September 2026 extract); this is public data, not a test of your tap.
EPA treatment records (state-reported) list chloramines for Gainesville Regional Utilities. EPA record
EPA's records list no health-based violations for Gainesville Regional Utilities for compliance periods starting since July 1, 2021. Lead, 90th percentile: 0.7 ppb at the latest result since July 2021, at or below EPA's 15 ppb action level (EPA SDWIS, monitoring period January to December 2025). In the EPA UCMR 5 data we use, PFOS and PFOA were not detected at or above EPA's reporting level in any of Gainesville Regional Utilities' 2 samples. Scored against health guidelines that are stricter than legal limits, using public utility data. Not a test of your tap.
The 90th percentile is a system-wide measure from homes sampled under EPA's lead rule; it isn't a result for your home.
EPA UCMR 5 data, samples through June 2026.
0 contaminants above health guidelines (of 12 detected)
No detected contaminants were above their published health guidelines in the most recent data.
Lead: 0.7 ppb (90th percentile of tap samples, January to December 2025). EPA action level (90th percentile): 15 ppb.
Lead is measured at the tap in homes selected because they are most likely to have lead plumbing. EPA says lead in drinking water mainly comes from pipes, solder and fixtures in service lines and buildings, not from the water source. Your home's plumbing matters more than the utility's number. EPA's goal (MCLG) for lead is zero.
California's public health goal for lead is 0.2 ppb.
If your home is older or may have a lead service line, ask your utility (it must keep a service-line inventory) or have your tap tested by a state-certified lab.

These are EPA's and Florida DEP's public records for this water system, shown as of October 14, 2026. If you represent this utility, or think a record here is wrong, tell us: Report an error. If the error is in EPA's or Florida DEP's own records, the state drinking water program can correct it there, and this page updates at our next data refresh.
A legal limit is an enforceable standard, set by the EPA under the Safe Drinking Water Act. Limits weigh health research together with the cost and feasibility of treatment. A health guideline is published by public-health sources and based on health research alone. A utility can meet every legal limit and still be above a published health guideline.

Gainesville Regional Utilities does not buy water from another system, according to EPA SDWA records. No other utility in this data buys water from it. (July to September 2026 extract.)
None of the 12 detected contaminants were above their published health guidelines in EPA SDWA, EPA UCMR and Florida DEP data, 2018-2025.
Chloramine is a disinfectant made by combining chlorine and ammonia. Some water systems use it in place of free chlorine. The public data used on this site (EPA SDWA, EPA UCMR and Florida DEP data) does not record which disinfectant Gainesville Regional Utilities uses, so we do not say. Your utility can tell you.
The score starts at 100. It goes down 8 for each contaminant above a cited health guideline whose source states a cancer basis, 5 for each other contaminant above its cited guideline, 5 for each of PFOA and PFOS averaging above the 4.0 ppt limit in EPA's 2024 PFAS rule, 10 for each contaminant whose average of all samples is above EPA's legal limit (instead of its guideline step), and 1 for each contaminant with a cited cancer-based guideline that is detected below it. Only guidelines with a cited document count. The lowest score is 5. Higher is better. For this report: nothing is subtracted, so the score is 100.
