Key Insights
- DNREC issued a recreational water advisory for Rehoboth Avenue in Rehoboth Beach due to high bacteria levels.
- The advisory was prompted by a water sample taken on July 2nd, which showed 10,462 colony-forming units of enterococcus per 100 milliliters, exceeding the threshold of 104.
- The beach remained open during the advisory, but swimmers were cautioned to limit their time in the water and avoid submerging their heads.
- Elevated bacteria levels are often associated with heavy rain and stormwater runoff, which can carry bacteria from pet waste and wildlife into waterways.
- A re-test conducted on July 3rd showed bacteria levels had dropped to 81 colony-forming units per 100 milliliters, leading to the advisory being lifted on July 4th.
- Despite the advisory, many beachgoers still entered the water, with varying levels of concern.
In-Depth Analysis
The DNREC uses enterococcus levels to determine recreational swimming advisories in Delaware. When levels exceed 104 colony-forming units per 100 milliliters, an advisory is issued. The rapid response and re-testing by DNREC demonstrate a commitment to public health and safety.
While the advisory was in effect, some visitors chose to engage in out-of-water activities, while others, unaware or unconcerned, continued to swim. This underscores the need for effective communication and awareness regarding water quality issues.
**How to Prepare:**
- Check local news and official websites (like DNREC's) for water quality advisories before visiting the beach.
- Avoid swimming in the water for at least 24-48 hours after heavy rainfall.
- If you choose to swim, avoid swallowing water and shower thoroughly afterward.
**Who This Affects Most:**
- Young children
- Individuals over 65
- People with weakened immune systems or medical conditions
