About this file
This document is a technical specification detailing toxic industrial chemical exposure guidelines and challenge concentrations for water treatment. The table outlines specific chemical contaminants and their required reduction percentages, including inorganic substances like arsenic (90% reduction), cyanide, mercury, volatile organic compounds (VOCs), gasoline/diesel components, pesticides, and radionuclides like uranium. Each chemical has a target influent challenge concentration with specified minimum reduction requirements ranging from 90-95%.
The specification appears directly related to a U.S. Army Combat Capabilities Development Command (DEVCOM) Request for Information (RFI) seeking an Individual Water Treatment Device capable of removing toxic industrial chemicals from fresh water sources. The device must meet stringent military requirements, including being lightweight (under 12 oz), compact, functional across extreme temperatures (-33°C to 52°C), capable of purifying 135 liters, have a 180-day unused service life, and remove chemical contaminants to levels mandated by the Defense Health Agency. The technology must be compatible with military hydration systems, meet Buy American Act requirements, and be environmentally safe during use and disposal.
