Where are water samples collected at LANL for rain runoff events?
Runoff samples are collected when a rainfall event causes flow in a drainage that crosses the Laboratory’s eastern or western boundaries. There are about 63 gaging stations equipped with automated sampling equipment located throughout the Laboratory. As shown in the accompanying figure, all of the runoff sampling stations are within or close to the Laboratory boundary. Runoff samples have been collected by LANL for 20 years and the results of analysis of the samples are reported in the yearly Environmental Surveillance Report. LANL’s Environmental Surveillance reports are available at the ENV-ES website, or from the National Technical Information Service, US Department of Commerce, 5285 Port Royal Road, Springfield , Virginia 22616 . A complete set of the reports is also available at the University of California Public Reading Room in Los Alamos.
