jupiter’s treated water quality results
The following tables list substances that may
be found in your tap water, as well as the
EPA’s established acceptable levels of these
contaminants. We are pleased to report that
our drinking water meets all federal and
state requirements. More information about
contaminants and potential health effects can be
obtained by calling the EPA Safe Drinking Water
Hotline, 1-800-426-4791.
The Town of Jupiter Utilities Department
routinely monitors for contaminants in your
drinking water according to federal and state
laws, rules and regulations. Except where

January 1, 2018 presented in this report is from various contaminants. From January 1 to
the most recent testing done in accordance with December 31, 2018, radon was detected in
current regulations.
