U.S. EPA Uses Solar Power to Fight Indoor Air Pollution http://cleantechnica.com/2009/09/14/zap-us-epa-uses-solar-power-to-fight-indoor-air-pollution/ http://cleantechnica.com/2009/09/14/zap-us-epa-uses-solar-power-to-fight-indoor-air-pollution/#comments Mon, 14 Sep 2009 21:40:35 +0000 Tina Casey http://cleantechnica.com/2009/09/14/zap-us-epa-uses-solar-power-to-fight-indoor-air-pollution/ Small solar panels provide enough electricity to power an exhaust system that almost eliminated TCE fumes in contaminated homes.The U.S. EPA has found that a simple, inexpensive rooftop solar panel can provide enough power to run a fan and remove toxic fumes from homes sitting on contaminated ground.  The EPA gave solar-powered venting a test run on several homes earlier this year, in a Superfund action aimed at tricholoroethene (TCE) vapors in a Grand Prairie, Texas neighborhood.  The pollution had been traced to a site occupied by the now-bankrupt Delfasco Forge company.

Compared to conventional remediation that involves weeks, months or even years of work along with a potentially huge carbon footprint for transporting or capping soil, the solar-powered exhaust systems took mere hours to install and resulted in an immediate 95% reduction in TCE vapors within the homes.  The EPA plans to extend the program this fall to other homes affected by the Delfasco site.

Mom always said to take your vitamins, and now it looks like she was right.  A good dose of vitamin B12 could be the key to cleaning up thousands of sites contaminated by solvents, particularly industrial degreasers and dry cleaning chemicals known as trichloroethylene (TCE) and tetrachloroethylene (perc).   These are two of the most common ground contaminants in the U.S., and when they get into aquifers, they are among the most difficult to remediate.  All that may be about to change.
