Delaware issues swimming advisory as Rehoboth Beach sees high bacteria levels
- A recreational water advisory was issued for Rehoboth Beach due to high bacterial levels detected.
- The advisory is effective from 3:31 p.m. on July 4, 2025, until 5:31 p.m. on the same day.
- Individuals with health concerns are advised to consult their doctors and exercise caution when considering recreational water activities.
On July 4, 2025, the Delaware Department of Natural Resources and Environmental Control (DNREC) announced a recreational water advisory for Rehoboth Beach because of high levels of bacteria found during routine water sampling. The advisory began at 3:31 p.m. and is set to remain in effect until 5:31 p.m. on the Fourth of July. Officials indicated that the elevated bacteria levels pose a greater illness risk to individuals with certain medical conditions or compromised immune systems, advising such individuals to consult their doctors regarding recreational water activities. The high bacteria levels at Rehoboth Beach, particularly at the beach located at Rehoboth Avenue, are attributed to significant rainfall that has occurred in the days prior to sampling. Heavy rainfall often causes runoff that can degrade water quality at recreation sites. DNREC's historical data indicates that water quality conditions at ocean beaches can fluctuate rapidly after rain events, leading to concerns such as this advisory. An additional water sample has been collected, and the advisory will be lifted once indicator bacteria levels fall below acceptable standards. Despite the advisory, authorities are monitoring the situation closely, and it is anticipated that this advisory may change shortly based on ongoing test results. The combination of hot weather with a heat index projected to feel like 100 degrees Fahrenheit also raises public health concerns, as individuals are encouraged to stay hydrated and recognize the risks associated with high temperatures. On a separate note, St. Croix River officials are also facing challenges related to recent storms and warm water conditions affecting test results. Although St. Croix’s officials have not implemented specific beach closures, they are conducting water testing to ensure safety for beachgoers. There is potential for the risk of contamination from bacteria and algae blooms, adding to the need for public awareness during this busy Fourth of July weekend. The situation on both coasts highlights the need for ongoing assessment and communication to safeguard public health in recreational waters.
