Water-quality advisory lifted for Herring Point
Update, 3 p.m., July 26 - The water-quality advisory for Herring Point in Cape Henlopen State Park has been lifted after a new collected water sample was below the recreational water quality limit.
Original post - A water-quality advisory has been issued for the beach at Herring Point in Cape Henlopen State Park following bacterial results that were above the recreational water quality standard. These bacteria most likely originate from wildlife sources, and increased rainfall, waves or wildlife feeding near the surf (shorebirds, marine mammals or other warm blooded animals) can result in these indicator bacteria washing into the near shore waters.
DNREC uses enterococcus levels to determine recreational swimming advisories in Delaware, with the threshold beginning at greater than 104 colony-forming units per 100 milliliters. According to the sample data found online, there were 309 colony-forming units during a test July 24.
The advisory will be lifted once indicator bacteria levels are within the recreational water limits.
