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.

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.

We can't tell for any one home. Lead pipes and lead solder were banned for drinking water in 1986. In Miami Beach, 67% of homes were built before 1980 and 17% before 1950 (ACS 5-year 2020–2024, table B25034; the Census groups homes by decade, so 1980 is the closest cutoff to 1986). Older homes are more likely to have lead pipes or solder, but many don't. To check yours, look up your address in City of Miami Beach's lead service line inventory or test your water.
