In response to a confidential request from an employee, a health hazard evaluation was conducted at the Metropolitan Sewer District, Mill Creek Facility (SIC-4952) in Cincinnati, Ohio. Concern had been expressed regarding exposure to sulfur-dioxide (7446095), nitrogen oxides, inorganic acids, metals, dioxins, furans, and bacteria in the sludge dewatering and incineration buildings. There were approximately 60 employees on three shifts with the potential for exposure in the sewer sludge dewatering and incineration buildings. Personal breathing zone and area air samples were taken along with surface wipe and bulk materials samples. Contaminant concentrations did not exceed current environmental evaluation criteria for the substances investigated. Health complaints were not reported by employees at the time of the site visits. The authors conclude that concentrations of cadmium (7440439), chromium (7440473), lead (7439921), nickel (7440020), and quartz (14808607) in dewatered sludge and surface dusts represented potential ingestion and inhalation hazards. The authors recommend measures to prevent contact with contaminated materials.
