EPA rules try to rein in runoff

Reduce Water Pollution

COUNCIL BLUFFS — Those towering snowdrifts will soon melt into headaches for land developers and homeowners alike, but the Environmental Protection Agency will add a catch to the muddy mix.

A final rule the agency issued in November to reduce water pollution from construction sites became effective in February. The regulations to improve water quality and reduce the amount of sediment washed from construction sites will be phased in over four years.

Erosion Control, and Nanotechnologies (NT)

Erosion Control Forum – Information on erosion control devices and resources Skip to content Abstract Nanotechnology (NT) The National Nanotechnology Initiative defines nanotechnology as understanding and controlling matter at dimensions between approximately 1 and 100 nanometers, where unique phenomena enable novel applications. Introduction Nanotechnology offers the potential to effectively treat contaminants in situ, avoiding excavation or the need to pump contaminated water out of the ground. The process begins with nanoparticles being injected into a contaminated aquifer via an injection well. Role of Nanotechnology Nanotechnology plays a crucial role in improving wind turbine performance...

Erosion Control Forum – Information on erosion control devices and resources Skip to content Bioventing Description Bioventing is an in situ remediation technology that uses microorganisms to biodegrade organic constituents adsorbed on soils in the unsaturated zone. Bioventing enhances the activity of indigenous bacteria and simulates the natural in situ biodegradation of hydrocarbons in soil by inducing air or oxygen flow into the unsaturated zone and, if necessary, by adding nutrients. During bioventing, oxygen may be supplied through direct air injection into residual contamination in soil. Bioventing primarily assists in the degradation of adsorbed fuel residuals, but also assists in the degradation of volatile organic compounds (VOCs) as vapors move slowly through biologically active...
