Green remediation strategies for water quality protection and conservation build on federal mandates such as the Clean Water Act and Energy Independence and Security Act. Cleanup at many sites involves high consumption of water for treatment processes such as contaminated sediment dewatering or soil washing, and at all sites requires management plans for stormwater runoff control during remedy construction and maintenance. BMPs focus on opportunities to reduce quantities of water consumed (intensity) during cleanup, re-use treated water, store or divert stormwater for beneficial use, and preserve natural hydraulic conditions.

Sample BMPs

  • Designing a closed-loop engineered system to maximize use of grey water during an ex situ treatment process
  • Using state-of-the-art, high efficiency water fixtures, valves, and piping in a treatment system wherever possible
  • Using treated water for onsite irrigation and wetlands enhancement
  • Substituting traditional, non-porous concrete with newer forms of pervious concrete, where needed, to increase subsurface water infiltration

Site-Specific Examples

  • An infiltrating evapotranspiration landfill cover and use of wastewater-treatment end products at Fort Carson
  • Optimized ground-water treatment to reduce water intensity for the NASA Jet Propulsion Laboratory
