Tag: sediment trap

Sediment traps are instruments used in oceanography to measure the quantity of sinking particulate organic (and inorganic) material in aquatic systems, usually oceans. This flux of material is the product of biological and ecological processes typically within the surface euphotic zone, and is of interest to scientists studying the role of the biological pump in the carbon cycle.

In the Chicago area, Thomas J. Kehoe is constantly dealing with issues related to impermeable soils. “There’s a lot of clay and glacial till, so when we have construction projects and get rain events, there’s a lot of runoff,” he says.

Putting the Brakes on Silt – Part 2

“For years, a crew would have to come out to a job site and install SiltSoxx in the field with big blower trucks,” says Zock. “Some people didn’t like that, and sometimes it was hard to get scheduled. That’s all changed.”

Filtrexx still has professionally certified teams all over the United

Trends in Stormwater Monitoring

Trends in Stormwater Monitoring

Today’s trends in stormwater monitoring and sampling are focusing on research as well as how to better manage stormwater onsite, industry observers say. Meeting National Pollutant Discharge Elimination System (NPDES) permit requirements continues to be a focus of many stormwater monitoring efforts. Instrument manufacturers are rolling out integrated systems designed

Natural Solutions: Make Your Next Sed Basin an Aquatic Biofilter

The next time you need a sedimentation basin, consider adding more benefits than just trapping eroding sediment. Instead, think about vegetating the banks and waterline with native plants that will attract interesting wildlife, add aesthetic value, green up your footprint…and save you money.     The Zona Rosa system includes

Landfills, Maintenance, and Success

If there is one idea that a landfill operator has to keep in mind, it is the fact that maintenance and repair are two different things entirely. Maintenance is what is done to prevent having to perform repairs. Maintenance is performed at regular planned intervals. Repair is unscheduled and performed

Reducing Impact

Reducing Impact

Try as they might, it’s impossible for contractors to build sound structures on solid ground without soil disturbance. Byproducts of the creative process, the particulates that can cause erosion onsite and can threaten water quality travel by way of dry soil meeting the air, vehicle tires, foot traffic, and water.

Putting the Brakes on Silt

Putting the Brakes on Silt

When it comes to versatility, erosion control contractors rely on silt fence and wattles-or other rolled or berm-shaped filtration products-as the workhorses of a job site. They are used as sediment barriers, as check dams to slow the flow of water and sediment (placed perpendicular to the downhill flow of

Staples of the Industry

Staples of the Industry

When it comes to choosing a silt fence or wattle to contain sediment and filter water for a construction project, cost is often a priority. Whether they’re made of natural fibers or geotextiles or a combination of both, some are less expensive up front; others cost more, but are more

Soil on the Move

Soil on the Move

Silt and sediment management devices may not be as impressive as retaining walls or as subtly beautiful as rain gardens, but they’re the first line of defense against soil that’s on the move. They range from simple wattles to trackout devices to sophisticated polymer treatment systems that reduce turbidity in

Managing Runoff From Start to Finish

Managing Runoff From Start to Finish

The Phase II regulations of the National Pollutant Discharge Elimination System (NPDES) require permittees to address six minimum stormwater runoff control measures. Two of them apply directly to stormwater design and construction on development projects. First, temporary erosion control best management practices (BMPs) must be implemented to keep runoff and
