BES Bioassay Laboratory Division conducts the biomonitoring program for central California's Grassland Bypass Project under the authority of the US Bureau of Reclamation. The project is designed to reduce selenium loading to wetlands and direct irrigation water into the San Luis Drain. [More Info] BES completed the Process Safety Management (PSM) and Risk Management Plans (RMP) for the bobsled/luge course in Park City, Utah. The system is cooled by one of the largest ammonia refrigeration systems in the world. [More Info] BES consulting services perform complete air quality evaluations. Indoor air quality is becoming a concern based on potential exposure to microorganism and chemicals in the indoor air. Indoor air quality investigations generally begin with occupant complaints which can result in Worker Comp filings. [More Info]
