We save your answer with the ZIP code, without your name or contact details, to improve how we match ZIP codes to utilities.
Lead: 3.1 ppb (90th percentile of tap samples, January to December 2023). 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.
Our systems aren't certified for PFAS.

EPA's service-area maps list Miami-Dade Water & Sewer Department for ZIP 33242, so we can't say which one serves a given address. Your water bill names your utility.
EPA's service-area maps split this ZIP code among several utilities, so we don't give it one score. Each possible utility's report has its own results from public records.
We save your answer with the ZIP code, without your name or contact details, to improve how we match ZIP codes to utilities. Answers don't change this page by themselves.
Each utility's report gives its own test years and the date of the EPA records it uses.

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.
