Jones Creek

Extensive water quality monitoring by the Loxahatchee River District, in partnership with the Town of Jupiter and the Florida Department of Environmental Protection, has shown consistently high fecal indicator bacteria (FIB) levels in Jones Creek canals. These bacteria are commonly found in the guts of humans and animals (dogs, racoons, and even wading birds), but they are also common in natural habitats, like mangrove swamps and in decaying vegetation. In Jones Creek bacteria (enterococci) concentrations are often far above (20 to 80x) the Environmental Protection Agency’s (EPA’s) recommended Beach Action Value (BAV) of 71 MPN/100mL for recreational waters. This is a concern because these tidal mangrove creeks are utilized by the public for recreation (e.g., boating, kayaking, paddle boarding and fishing).

The best available information suggests the high bacteria levels in Jones Creek are, in large part, the result the extensive organic-rich sediments, leaf litter and vegetation debris in the poorly flushed, choked waterway. Other factors may include animal excrement (predominantly dogs, racoons, and wading birds) entering the waterway, and other natural causes.  Despite all properties in the basin served by central sewer (i.e. no septic systems), molecular analysis of water quality samples in 2019 and 2020 also indicated very low concentrations of human sewage, possibly a single household, and we are working to identify the likely source(s).

The Department of Health advises against consuming fish or swimming in waters with high bacteria counts. We urge residents to pick up dog waste and never dump pollutants or refuse, including grass clippings, fish or other carcasses, into natural waterways, canals, or storm drains.

The Loxahatchee River District, Town of Jupiter and Florida Department of Environmental Protection are working to better understand the issue, and help develop sensible solutions. For more information, please see the links below.
