The Community Environmental Monitoring Program (CEMP) is a network of 29 monitoring stations located in communities surrounding and downwind of the Nevada Test Site (NTS) that monitor the airborne environment for manmade radioactivity that could result from NTS activities. The network stations, located in Nevada, Utah, and California are comprised of instruments that collect a variety of environmental radiological and meteorological data. The CEMP is a joint effort between the Department of Energy's National Nuclear Security Administration Nevada Site Office (NNSA/NSO), and DRI.

To manage the stations, DRI employs local citizens, many of them high school science teachers, whose routine tasks include minor maintenance of the equipment, collecting air filters and routing them to DRI for analysis. These Community Environmental Monitors (CEMs) are also available to discuss the monitoring results with the public, and are available to speak to community and school groups.

Program funding and equipment are provided by NNSA/NSO. DRI manages the program, provides technical direction, employs and trains CEMs, conducts public outreach activities and collects data to be analyzed by an independent laboratory.
