About this file
This file is a technical specifications document that provides challenge concentrations and minimum percent reduction requirements for various toxic industrial chemicals and materials that must be removed from water sources. The document lists specific requirements for inorganic compounds (arsenic, cyanide, mercury), volatile organic compounds (chloroform), petroleum products (benzene, toluene), pesticides (aldicarb, methamidophos), herbicides (paraquat), radionuclides (uranium), and dissolved solids. Each chemical is identified by its CAS number and has defined target influent challenge concentrations (in mg/L) and required minimum percent reductions ranging from 90-95%.
This document appears to be an attachment to a larger RFI seeking water purification technologies for individual soldier use. The specifications outlined in this document would be used to evaluate potential solutions' effectiveness at removing these specific contaminants from water sources to meet military exposure guidelines (MEGs).
