• Description:
  In response to an employer request, an industrial hygiene survey was conducted at the Metropolitan St. Louis Sewer Bissell Point Wastewater Treatment Plant (SIC-4952), St. Louis, Missouri. The facility received an average of 111 million gallons per day of wastewater. There were about 100 workers on three shifts. Personal breathing zone and general area air samples were collected along with bulk samples of waste activated sewage sludge and wastewater. Air samples were tested for hydrogen-sulfide (7783064) and endotoxin. No overexposures were noted during the investigation. Waste activated sewage sludge and wastewater samples were analyzed for headspace volatile organic compounds (VOCs). General air samples were analyzed for VOCs. General air samples for individual VOCs were below respective occupational limits. Waste activated sewage sludge and incinerator ash bulk samples were analyzed for elemental composition. The author concludes that belt press room workers were not exposed to hydrogen-sulfide concentrations exceeding the NIOSH ceiling limit of 10 parts per million at the time of the survey. The author recommends that daily monitoring for hydrogen-sulfide be continued due to potential seasonal variations in air concentrations. Personal hydrogen-sulfide monitors and respiratory protection should be used when air concentrations equal or exceed 10 parts per million.
