Billing, service and outages are handled by the utility; your water bill names it and lists how to reach it. ScoreYourWater is not your water company and never handles water billing.
Rex Utilities (Redavo) has a Water Score of 50 out of 100 (Weak) on our scale. 5 of 35 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.
We didn't find chloramine in Rex Utilities (Redavo)'s EPA treatment records. That's not a complete list; your utility's annual water quality report says which disinfectant it uses.
Rex Utilities (Redavo) (EPA water system FL4131206) serves about 350 people and is in Miami-Dade County (EPA water system boundaries do not match it to any ZIP code area in our data). It buys water from City of Homestead. In EPA SDWA, EPA UCMR and Florida DEP data from 2018-2025, 5 of 35 detected contaminants are above published health guidelines, for a Water Score of 50 (Weak); PFOA and PFOS averaged above 4.0 ppt, the limit in EPA's 2024 PFAS rule (water systems must meet it by April 2029; EPA has proposed allowing until 2031). Scored against health guidelines that are stricter than legal limits, using public utility data. Not a test of your tap.

| PFOS*EPA's 2024 rule sets a limit of 4.0 ppt; water systems must meet it by April 2029. In May 2026 EPA proposed allowing extensions to April 2031. EPA's goal (MCLG) is zero. | 22.5 pptaverage of all sampleshighest sample 26 pptdetected in 4 of 4 samples | 4 ppt | None published | 2025 |

The level shown is the average of all of the utility's results in the years shown, with results below EPA's reporting level counted as zero. The highest single result and the number of samples in which it was detected are shown with each level. Each of these averaged above 4.0 ppt across all of the utility's samples, with results below the reporting level counted as zero. EPA judges compliance on a running annual average at each sampling point, so our combined average is a guide, not a compliance result. Under EPA's 2024 PFAS rule, water systems must meet the PFOA and PFOS limits (4.0 ppt each) by April 2029; in May 2026 EPA proposed allowing extensions to April 2031. Results before then are monitoring data, not violations.
Public data from EPA UCMR 5, 2023–2025. It isn't a test of your tap, and your water can differ. Last checked against the Federal Register: October 25, 2026.
Lead: 0.4 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.

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.

5 of 35 detected contaminants were above their published health guidelines in EPA SDWA, EPA UCMR and Florida DEP data, 2018-2025. The highest: Bromodichloromethane at 307 times its guideline, Dibromochloromethane at 132 times its guideline and Arsenic at 125 times its guideline. PFOA and PFOS averaged above 4.0 ppt, the limit in EPA's 2024 PFAS rule (water systems must meet it by April 2029; EPA has proposed allowing until 2031).
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 Rex Utilities (Redavo) 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: 100 minus 8 times 5, minus 5 times 2 (PFOA and PFOS average above 4.0 ppt, the limit in EPA's 2024 PFAS rule) is 50, so the score is 50.
