State Water Resources Control Board <br /> Division of Water Quality <br /> GAMA Program <br /> REMEDIATION & TREATMENT TECHNOLOGIES <br /> The removal of DBCP from water can be accomplished through different methodologies, <br /> including air-stripping and filtration using granulated activated carbon. DBCP can also be <br /> removed using hydrogen peroxide combined with a catalyst (Fenton's Reagent). Ozone is a <br /> strong oxidant that can react with and oxidize DBCP to carbon dioxide and water. <br /> Zero-valent iron (Fe°) is frequently used in situ to remove DBCP in passive remediation <br /> systems. In the simplest application of this technology, a permeable reactive barrier or iron <br /> wall, is installed by digging a trench perpendicular to the direction of groundwater flow and <br /> back-filling it with iron. Water that passes through the zero-valent iron barrier is stripped of <br /> DBCP. <br /> The US EPA approved treatment method for the removal of DBCP in drinking water is to use <br /> granulated activated carbon in combination with packed tower aeration. <br /> HEALTH EFFECT INFORMATION <br /> Ingestion of DBCP results in gastrointestinal distress and pulmonary edema. The likelihood of <br /> exposure to DBCP through food sources is extremely low since DBCP rapidly volatilizes when <br /> exposed to air and sunlight. Additional exposure pathways are through inhalation and direct <br /> contact. <br /> Acute inhalation exposure to DBCP in humans results in moderate depression of the central <br /> nervous system, kidney and liver damage, and pulmonary congestion. Dermal exposure may <br /> irritate the skin and eyes in humans and animals. Even low exposure to DBCP by humans may <br /> cause sterility in men or other male reproductive effects, such as decreased or no sperm <br /> counts. There is some evidence that DBCP may have the potential to cause cancer with <br /> lifetime exposure at levels above the MCL. <br /> Revised: July, 2016 <br />
