Post-Cerro Grande Fire Environmental Sampling Data: Upper Los Alamos CanyonAlluvial Groundwater Samples Collected in June 2000

摘要

The Los Alamos National Laboratory's (the Laboratory's) Environmental Restoration(ER) Project collected alluvial groundwater samples in upper Los Alamos Canyon from June 21 to June 27, 2000 (after the Cerro Grande fire). This report summarizes the analytical results of those sampling efforts. Sampling was conducted before the summer monsoon season and before significant postfire flooding occurred in Los Alamos Canyon. This sampling provided baseline data for later comparison with data from samples collected during the monsoon season, because the chemistry of the floodwater could affect groundwater quality in the canyon. These groundwater sample locations were selected to represent potential spatial variability in water quality in Los Alamos Canyon and were chosen from existing alluvial groundwater monitoring wells.
