Summary

There is increasing pressure on construction site managers to reduce the off-site impacts of storm water runoff on streams, lakes, and estuaries adjacent to their projects.  Traditional erosion and sediment control measures, even when properly installed and maintained, will often release highly turbid water to the environment.  Increasing scrutiny and regulation of these discharges is driving developers to seek cost-effective practices to address the turbidity that standard sediment traps and basins cannot capture.  With over two decades of research including construction site testing, we’ve found that turbidity can be reduced to often two orders of magnitude lower using chemical treatments.

This workshop will provide participants with the background and knowledge to implement a wide range of methods to reduce turbidity in construction site storm water, in addition to traditional erosion and sediment controls.

The workshop is designed to provide practical information on the use of chemical treatments to improve water quality for professionals involved in designing and managing erosion, sediment, and turbidity control on construction sites.

Test Your Sediment Samples

Bring one or more samples of sediment from your own construction sites. You will have an opportunity to practice the screening process to match the best polymer to your sediment. Bring about 200 grams or a 1/2 cup in a small container.
