Wetlands Can Be Effective in Improving Water Quality
• Treatment wetlands established to only treat wastewater
• Treatment wetlands established to polish wastewater effluents and provide wetland habitat
• Areas of degraded or historic wetlands used to establish treatment wetlands to polish wastewater effluents while enhancing the wetland habitat
• Both natural and constructed wetlands receiving appropriate loadings
Wetlands Can Be Effective in Improving Water Quality
• EPA's Wetland Program has established a website providing sources of constructed wetlands information at “http://www.epa.gov/owow/wetlands/watersheds/cwetlands.html" that includes …– a series of 17 case studies of constructed treatment
wetlands– Guiding Principles document– an EPA design manual– technology assessments– databases– bibliography– etc.

USGS, California DWR and UC Davis large-scale Delta “carbon farm” - DWR has awarded USGS and UC Davis a three-year, $12.3 million research grant to take the concept of carbon-capture farming to full-scale in a scientifically and environmentally sound way.- To capture or contain the carbon, farmers would “grow” wetlands. In doing so, they would begin to rebuild the Delta’s unique peat soils, take CO2 out of the atmosphere, ease pressure on the Delta’s aging levees and infuse the region with new economic potential.
