Abstract
Environmental and breathing zone samples were analyzed for acrylamide (79061), butyl-acetate (123864), acetic-acid (64197), and hydrogen-sulfide (7783064) at Big Dry Creek waste water treatment facility (SIC-4959), Westminister, Colorado in July and November, 1984. Noise monitoring was also conducted. The survey was requested by a facility representative to evaluate potential health hazards associated with chemicals used in the waste water treatment process and from noise. All airborne samples were below their respective standards or criteria. Personal noise levels ranged from 87.4 to 90.9 A-weighted decibels (dBA), the highest values occurring in the sludge process building, range 85 to 100dBA. The author concludes that a health hazard from chemical over exposure at the facility does not exist. A potential hazard does exist from noise over exposure. Evaluation of all air compressors, periodic noise monitoring, use of hearing protective devices using EPA noise reduction ratings, and an employee education program about chemical and noise exposure hazards are recommended.
