(re:21300 Mann Road) <br /> To: Michael <mkith a,sj og v.org> <br /> The Environmental Working Group (https://'www.ew�org/about- <br /> us) states that two ways to reduce DBCP are activated carbon and <br /> reverse osmosis. (https://www.ewg.org/tapwater/contaminant.php?contamcode=2931) <br /> California Department of Health Services, Division of Drinking <br /> Water, describes "It was assumed that systems currently treating <br /> ("treated" database) were using granular activated carbon (GAC) <br /> treatment", page four, 2) Treatment Costs, and that those in use <br /> would not have any impact to the GAC capital costs - They would <br /> not be incurred as this treatment was already in place. <br /> This is a study on activated carbon absorption of DBCP into carbon <br /> made from nut shells; Life Systems Water uses a coconut shell <br /> 1 <br />
