What action should be taken if dewatering discharges are found to be more turbid than receiving waters?

When dewatering discharges are found to be more turbid than the receiving waters, it is crucial to cease the discharge immediately. Turbidity is a measure of water clarity and high turbidity can indicate the presence of suspended particles, which can harm aquatic life by blocking sunlight and disrupting habitats. Allowing turbid water to enter a body of water can lead to environmental damage and may also violate regulatory requirements aimed at protecting water quality.

By stopping the discharge, you can prevent further degradation of the receiving waters and reassess the treatment methods being used for the discharge. This action allows operators to explore other management options that could involve treating the water to lower its turbidity levels to comply with water quality standards before any discharge occurs. This proactive approach not only helps in safeguarding the environment but also ensures compliance with legal and regulatory obligations pertaining to stormwater management.
