Sandia National Laboratories/New Mexico (SNL/NM) proposes to install 7 new storm-water monitoring stations at various sites east of Technical Areas II and IV. Five of the 7 new monitoring points would be "in-ground samplers." These locations would be manually dug using hand tools (shovels, posthole digger, bars, etc.) to install the samplers. Each monitoring point would be 24 inches (in). deep by 18 in. in diameter. A 12-inch diameter polyvinyl chloride pipe would be placed in the ground to house the storm water collection device. The remaining two samplers would be portable and would not require any excavation.
