Spring Creek

In addition to the James River area, chlordecone residues of 0.025 and 0.23 mg/kg (ppm) were detected in trout and suckers, respectively, collected from Spring Creek 18 miles downstream of the Nease Chemical Plant in Pennsylvania (EPA 1978c). This plant produced small quantities of chlordecone from 1966-1974 (Epstein 1978). [Pg.194]

Spring Creek, Virginia, they observed some calcite precipitation at SI, (calcite saturation index) values between +0.1 and -t-0.7. Major precipitation ofcalcite as travertine took place at a waterfall where the local turbulence facilitated COt oulgassing. The CO2 loss caused the water to exceed calcite saturation by up to 20 times SI, = +1.3). [Pg.223]

Surface and subsurface drainage below the plant flows into Spring Creek, a stream known for its fine trout fishing, scenic beauty, and the location of Benner Springs Fish Research Station, operated by the Commonwealth of Pennsylvania (Figure 1). Water samples in this stream near the source of contamination have been found to contain 20 to 90 ng/kg (ppt) of the marker compound during the past 10 years Q) ... [Pg.258]

Spring Creek and its tributary, Slab Cabin Creek, are perched above the regional water table from Route 26 downstream towards Houserville. Water levels in well J of Figure 1 drilled within less than ten feet of Spring Creek commonly stand from 11 to 13 feet below the level of the stream surface as do water levels in test well K located along its valley slope or wall (Figures 1 and 5). Both wells were cased into bedrock and obtain water from solution openings. [Pg.266]

A downward component of flow is present during periods of high seasonal water table and when Spring Creek and Slab Cabin Run are in flood. During periods of flood, surface water comes into contact with isolated carbonate bedrock outcrops located along the valley slopes of these creeks and provide local pathways for contaminated surface waters to enter the karst aquifer. Elsewhere, flood waters come in contact with residual and transported soil that blankets the lower portion of valley slopes, hence, preventing the direct entry of surface water into the local aquifer. [Pg.267]

Although it has been shown that surface water flows downward through the flood plain of Spring Creek, finding a chemical example of this interaction in a stream bed for the marker compound requires extremely careful work which has not yet been completed. [Pg.270]

The marker compound was detected in an upland well located north of the plant and across the western groundwater divide of this subbasin The static water level in this well stands above the elevation of Spring Creek and water levels near the plant. It is unlikely that contaminated groundwater crossed beneath this groundwater divide through upturned, somewhat poorly permeable beds of dolomite and the thin, artesian sandstone aquifer ... [Pg.271]
