In response to a request from the Mayor of Louisville, Kentucky, a health evaluation was made of conditions at the Morris Wastewater Treatment facility of the Metropolitan Sewer District. On March 26, 1977, a strong smelling, highly viscous, sticky substance entered the facility, coating the bar screens and grit collection systems in the primary treatment area. The facility was evacuated and closed on March 29 when it was learned that the contaminant included hexachlorocyclopentadiene (77474) (HCCPD) and octachlorocyclopentene (706785) (OCCP) dispersed in about 6 tons of fuel-oil which had been dumped directly into the municipal sewer system's Western Outfall Sewer. Workers experienced headache; eye, nose and throat irritation; chest discomfort; shortness of breath; skin irritation; nausea; and fatigue which lasted up to 6 weeks in 15 to 46 percent of the cases. At least one abnormal liver function was noted in 19 percent of the crew of exposed workers wearing protective gear. NIOSH offered technical assistance during the cleanup period and as of January 1, 1978, the facility was treating about 85 million gallons of flow per day. Two major work efforts remained at that time: approximately 9,700 linear feet of the Western Outfall Sewer and about 6,780 linear feet of the Western Interceptor Sewer needed to be cleaned. The authors recommend continued medical monitoring of personnel and cleaning techniques to be used.
