The FDEP general permit for dewatering requires a distance of how many feet from a known contamination source?

The requirement for a distance of 500 feet from a known contamination source in the FDEP general permit for dewatering is critical to ensure the protection of water quality and public health. This distance is designed to minimize the risk of contaminated groundwater or surface water entering the dewatering operation. Maintaining this buffer zone helps to prevent the potential spread of contaminants that could arise from nearby sources, which is essential for safeguarding both the environment and the effectiveness of the dewatering process.

This standard reflects an understanding of the potential movement of contaminants through soil and ground water, ensuring that dewatering does not exacerbate pollution issues. The 500-foot distance is established as a best management practice to mitigate risks and promote responsible environmental stewardship during dewatering activities.
