Silt Screen to Prevent Contamination

Backyard Project with Silt Screen

silt screenQuestion: We are doing a project in our backyard which requires a silt screen to prevent an contamination from getting into a stream corridor. I don't know what I'm looking for or what to call it. The DEC advised us to use silt screens along the boundary of the water's edge.

We want to build a retaining wall to replace existing levels. We were told we needed the netting in case of spills or contamination into the waterway. The length across the back yard is approximately 60 feet. Can you help me with this?

Answer: You can certainly use a silt screen to prevent contamination. GEI Works has a number of erosion control supplies that could work in your situation.

There are two different types of silt screens—land-based and water-based. Each is useful depending on the application and location.

Land-Based Silt Screen

staked turbidity barrierWith a land-based silt fence, a permeable geotextile fabric is erected between wooden stakes along your project area. When the water from your site reaches the barrier, contaminants are kept by the fence while water flows through.

Another land-based option is the staked turbidity barrier. A staked turbidity barrier is similar to the silt fence except it is impermeable. The runoff is directed completely away from the stream. This will only work if you have a designated location to send your contaminated water.

See more information on the Staked Turbidity Barrier.

Water-Based Silt Screen

The water-based silt screen, called a turbidity curtain, is placed in the water to control suspended particles in the water and prevent them from spreading. Any contaminants from your project would settle and stay in the designated area.

Natural Filtration with Coir

Made from 100% biodegradable coconut coir fiber, you could use coir logs, coir blocks, or coir silt checks to prevent silt from contaminating the stream. The coir products line the stream, stopping any pollutants from entering.

The type of erosion prevention method that's best for your project will be determined by the specifics of your work area and building requirements. Coir blocks can also be used to help build a retaining wall, and its natural fibers allow vegetation to take root.
