Technical Assistance Report No. TA-79-040-1033, Big Creek Water Pollution, Control Plant, Roswell, Georgia.
Comprehensive environmental and medical surveys were conducted at the Big Creek Water Pollution Control Facility (SIC-4952) in Roswell, Georgia. From June, 1979, through March, 1980, and during September, 1980, and January, 1981. The surveys were requested by the Chief Engineer for the Fulton County Department of Public Works, in Atlanta, Georgia, on behalf of approximately 17 workers, several of whom had complained of headache, eye irritation, fatigue, dizziness, lethargy and chest tightness. No obvious source for the workers' symptoms could be detected in the investigation. The only significant amounts of toxic substances identified were the 1,1,1- trichloroethane (71556) and lighter alkane vapors detected in a sewer manhole. Immunologic testing against fungi and amoeba found in the facility environment were negative. Lung function tests of workers were within normal parameters. Blood tests were normal although seven workers had elevated immunoglobulin counts suggestive of a nonspecific immune response. The authors conclude that the cause of the reported symptoms could not be ascertained and recommended the use of gas detection equipment, air blowers to ventilate sewer lines, worker training in the use of self contained breathing apparatus, and regular medical monitoring of all employees.
