Relationship between industrial discharges and contamination of raw water resources by perfluorinated compounds: part II: Case study of a fluorotelomer polymer manufacturing plant.
In this study, the concentrations of 10 perfluorinated compounds (PFCs) were measured in effluents of a fluorotelomer polymer manufacturing plant and its wastewater treatment plant. A 50-fold increase between the two effluents mass flows was observed. The water quality of two drinking water treatment plants located downstream at 15 and 25 km from the manufacturing plant was examined. An increase of the sum of PFCs was observed between the river (30 ng/L) and an alluvial well (70 ng/L), and between the raw water (9 ng/L) and the outlet of a biological treatment (97 ng/L). These results indicate a possible degradation of fluorotelomers, occurring during wastewater treatment, sediment infiltration in the alluvial aquifer, and drinking water treatment.
