Evaluating the Effect of Holding Time and Storage Temperature on the Chemical Stability of Drinking Water Samples Collected from Military Forward Deployed Environments
Abstract
The US Army Public Health Command-Army Institute of Public Health uses Environmental Protection Agency (EPA) approved drinking water methods, or in-house developed and validated screening methods, when analyzing water samples from forward deployed environments. Each method specifies pre-analytical Maximum Holding Times (MHT)and storage temperatures for samples. The analytes in this study have MHTs as low as seven days and as high as 180 days and all require a storage temperature of 4 C. It is very challenging for US military forces to meet these guidelines when shipping samples from remote locations to the US for laboratory analyses. This study investigated the chemical stability of treated watersamples when exceeding the EPA MHT and storage temperature. The compounds studied included select volatile and semi-volatile organic compounds (VOC and SVOC), Endothall, Diquat, Paraquat, and Cyanide.
