Hanahan, S.C. Advisory Issued Due to Algal Bloom
Residents in Hanahan, S.C. are advised to avoid the Goose Creek Reservoir due to a naturally occurring algal bloom. This advisory has been issued by the Charleston Water System (CWS) and the South Carolina Department of Environmental Services (SCDES) to ensure the safety of the community and its pets.
Ongoing Water Testing
The SCDES is conducting tests on the water to determine the presence of toxins related to the algal bloom. While these tests are underway, the CWS has assured residents that the drinking water in the area remains completely safe as the reservoir is not currently utilized as a drinking water source. As an immediate safety precaution, officials recommend that people and pets stay out of the reservoir until test results become available.
Health Risks of Algal Blooms
Health concerns have been raised regarding activities such as swimming, kayaking, fishing, or wading through the water due to the potential for illness. The ingestion of contaminated water or exposure to mist that may contain algal toxins poses serious health risks, particularly for children and those with existing health conditions. Pet owners are also warned that pets may become ill from licking their fur after being in the water, increasing the risk for dogs and cats to develop health issues from algal toxins.
It is also important to note that eating seafood affected by the algal bloom can pose additional health risks. Therefore, residents are urged to take the advisory seriously and refrain from recreational activities in and around the reservoir.
Next Steps and Recommendations
The SCDES is expected to provide test results next week, with updates to be posted on their Harmful Algal Bloom page if toxins are detected. Not all algae blooms are harmful; they often occur due to warm temperatures and excess nutrients like nitrogen and phosphorus, which can lead to undesirable blooms.
Preventive Measures for Residents
To prevent future algal blooms, residents and businesses in the area are encouraged to apply fertilizers carefully and prevent soil erosion that may lead to nutrient runoff into waterways. Awareness and action at the community level can significantly contribute to maintaining a healthy environment.
The CWS provides water service to over 500,000 people in the Charleston area, demonstrating the importance of keeping local water bodies clean and safe for all residents.
