SITE DESCRIPTION This is a former National Starch Chemical Company Superfund site that is currently owned and operated by AkzoNobel Surface Chemistry LLC. The site has extensive chemical contamination, primarily caused by the practice of using unlined trenches and a lagoon to handle and dispose of more than 350,000 gallons of wastewater containing many different kinds of chemicals. HYDROGEOLOGIC DESCRIPTION The bedrock beneath the site is part of the Churchland Plutonic Suite, which consists of granite and other plutonic intrusive rock. The bedrock is overlain by saprolite which varies in thickness from approximately 60 feet to approximately 10 feet. Surficial soils are primarily a mixture of silt and clay, with an increase in particle size with depth to coarse sand and weathered rock just above the surface of the bedrock. Shallow ground water is encountered at depths ranging from approximately 7 feet near the unnamed tributary stream to more than 50 feet at uphill locations. The average hydraulic gradient in the most shallow groundwater unit is approximately 2.1%, and assuming an effective porosity of 15% and hydraulic conductivity of 1 ft/day, the average groundwater flow rate would be on the order of 0.14 feet per day. EXTENT OF CONTAMINATION The exact size of the impacted area is not known. Based on the sampling data from monitor wells of various depths, the impacted area is at least 1,500 feet long, 1,500 feet wide, and mostly contained in the saprolite and shallow bedrock in an approximate vertical extent of 100 feet (Figures 3, 7, 8 and 9). PROPOSED INJECTION The injectant is fluorescein dye, which is used as a tracer to trace the path of groundwater flow. Only one well will be used for the injection, which will be into deep fractured bedrock, and the injection will be performed in such a manner as to have no hydraulic impact on the ground water in the vicinity of the injection well. This will be achieved by slowly introducing the dye in a flow stream that will be equal to a simultaneous withdrawal of water from the well, and a closed -loop circulation will take place within the well and the recirculating pumping system that will bring the dye to a uniform concentration in the well's hydraulic column (approximate volume of 71 gallons). The concentration of dye will gradually decline over time as the dye -laden water slowly leaves the well and is replaced by ordinary ground water. The volume of injected water will be less than 1% of the total volume of water impacted by the contamination. HOW IT WORKS This is a tracer substance and has no significant or intended remedial impact. MONITORING The monitoring will consist of sampling the injection well for the concentration of fluorescein dye immediately after injection, and then at 1, 2, 3, 7, 14, 28, and 42 days after the injection, or until the dye concentration declines to less than 90% of its initial concentration. Laboratory analysis will be used, and the schedule may be adjusted based on the rate of dye dissipation. We are adding the requirement of visually examining the nearby unnamed tributary stream during each sampling event, and sampling the stream during each sampling event for the concentration of the dye, provided the stream is flowing. EPIDEMIOLOGY On July 31, 2000, the DHHS' Epidemiology Branch provided comments on Fluorescein for groundwater tracing. Dr. Luanne K. Williams did not present any information that would preclude the use of these products for injection but did provide a health risk analysis and worker safety precautions, which are in Part X of the attached permit. REGIONAL OFFICE COMMENTS Maria Schutte and Andrew Pitner of the Mooresville Regional Office recommend issuance of this permit. They recommend requiring ongoing visual inspections of the unnamed tributary stream adjacent to the injection well, and the sampling of this stream (when flowing) for fluorescein dye. The permit will require a visual inspection of the stream and sampling of the stream at every monitoring (sampling) event of the proposed monitoring schedule (see above).
