UPDATE: 'No-swim' advisory lifted at Lantana Beach but remains at Dubois Park in Jupiter

A no-swim advisory is in place for Dubois Park in Jupiter, seen here in December 2019.

4:30 p.m. Thursday update: Officials have lifted the "no-swim" advisory for Lantana Beach, but the warning still remains in place for Dubois Park in Jupiter, according to the Florida Department of Health for Palm Beach County.

The water at Lantana Beach showed "moderate" levels of the enterococcus bacteria from a sample taken on Wednesday. The levels of the bacteria are now between 35.5 to 70.4 parts per 100 milliliters of water, an improvement from their recent "poor" rating with 70.5 parts or more per 100 milliliters of water.

The water at Dubois Park still showed "poor" levels of the bacteria in its latest sample. Officials caution people against swimming there until the advisory is lifted. More tests are expected in the next few days.

Original story:

Health officials are advising people not to swim at Dubois park in Jupiter and at Lantana Beach after tests this week found high bacteria levels in their waters.

Water samples at both locations on Monday showed “poor” levels of the enterococcus bacteria, which can lead to internal infections, the Florida Department of Health for Palm Beach County said. Higher levels could have been caused by animal waste, heavy recreational usage, high surf, winds, and tides or runoff following heavy rains.

A no-swim advisory does not close a beach. It urges anyone who goes into the water to bathe promptly after getting out of it.

The waters at the beaches have 70.5 parts or more of enterococcus per 100 milliliters of water. A safe level is no more than 35.

The health department takes biweekly samples of the beach waters at 15 locations from Boca Raton to Jupiter.

The advisory will remain in effect until health officials obtain a sample in the good or moderate range at the beaches. The next round of samples is due to be taken before the weekend.
