0 contaminants above health guidelines (of 10 detected)
No detected contaminants were above their published health guidelines in the most recent data.
Lead: 0.9 ppb (90th percentile of tap samples, January to December 2024). 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 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.

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 Town of Jupiter Water 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.
