Case Study Two:

DOT Highway Construction.

• Excessive rainfall amounts
  
• Scheduling and project delays
  
• Sensitive nearby waters
  
• Stringent discharge requirements
  
• Groundwater flows
  

Approaches and Solutions:

Heavy sediment laden water threatened to breach the temporary retention basin sidewalls resulting in contamination of a nearby river.

Liquid Biostar-CH was injected into the water as it was pumped from the basins.

Weir tanks were employed to pre-settle the suspended solids prior to passing through a sand filtration system.

Clean water was allowed to be discharged directly into the river.
