CRS" (Chemical Reducing Solution) is an iron-based reagent that facilitates <br /> biogeochemical in situ chemical reduction (ISCR) of halogenated contaminants N <br /> such as chlorinated ethenes and ethanes. CRS is a pH neutral, liquid iron solution <br /> that is easily mixed with 3-D Microemulsion' Factory Emulsified before injection <br /> into a contaminated aquifer. CRS provides a soluble, food-grade source of ferrous <br /> iron (Fe'-), designed to precipitate as reduced iron sulfides, oxides, and/or <br /> hydroxides. These Fe" minerals are capable of destroying chlorinated solvents " <br /> via chemical reduction pathways, thus improving the efficiency of the overall <br /> reductive dechlorination process by providing multiple pathways for contaminant Example of c <br /> degradation in groundwater. <br /> For a list of treatable contaminants with the use of CRS, view the Range of Treatable Contaminants Guide <br /> Chemical Composition <br /> • Water 7732-18-5 <br /> • Ferrous Gluconate 299-29-6 <br /> Properties <br /> • Appearance - Dark green to black <br /> • Odor - Odorless <br /> • pH 6.0 to 8.0 <br /> • Density - Approximately 1.0 grams per cubic centimeter (0.9 to 1.1 g/cc) <br /> • Solubility - Miscible <br /> • Vapor Pressure - None <br /> • Non-hazardous <br /> Storage and Handling Guidelines <br /> Storage Handling <br /> Store in original tightly closed container Avoid prolonged exposure <br /> Store away from incompatible materials Observe good industrial hygiene practices <br /> Recommended storage containers: plastic-lined Wear appropriate personal protective equiprr <br /> steel, plastic, glass, aluminum, stainless steel, or Avoid contact with eyes, skin, and clothing <br /> reinforced fiberglass Avoid breathing spray mist <br /> Store in a cool, dry, well-ventilated place Use with adequate ventilation <br /> Keep away from extreme heat and strong oxidizing <br /> agents <br />
