An analysis of the bally groundwater contamination

Gomes, M. Performing necessary additional studies in the pre-design phase to evaluate the configuration of any additional groundwater extraction well s required. This well is used, in conjunction with uncontaminated spring water, for potable water supply within the Borough. After extensive studies it has been concluded that a specific source of contam- ination was not found. Dash, A. This area was investigated because it lies hydraulically downgradient of the former lagoons and current and former degreasing areas, and hydraulically upgradient of contaminated shallow wells MW and MW S. Description of the Selected Remedy The remedial alternative presented in this document is the permanent remedy for resolving the groundwater contamination at the Site. Plume contaminant movement has become more controlled since pumping and air stripping pilot testing began at Well No. Institutional controls relative to coniservation of water would permit the springs to meet demand at other times if nonroutine maintenance of the municipal well was required. The major use of TCE was curtailed in about with the cessation of production of the meat display cases. In the s the main product line became continuous line, porcelaincoated meat display cases and porcelain panels for use in constructing building facades.

For Class C chemicals, an additional uncertainty factor of 10 is used to reflect possible carcinogenic effects. Field screening readings are summarized in Table 2 of the RI Report.

The test data yielded a transmissivity T1 of 7. The second area is a gallon degreasing tank for cleaning small parts used to fabricate an interlocking mechanism for the insulated panels. Sections - This part deals with provisions for nonattainment areas. The Commonwealth of Pennsylvania has reviewed, commented and concurred on this Record of Decision. The final PADER Air Operating Permit for this treatment system will establish acceptable performance standards for air emissions and should, therefore, be incorporated as the primary ARAR for air emissions at this site. The plant has been in operation approximately 1, feet south of the Municipal Well No. Surface drainage is captured in two principal drainageways, both unnamed tributaries to the West Branch Perkicnen Creek. An infiltration rate of 5. Abandoning appropriate existing private wells and implementing institutional controls on the use of operable private wells and the construction of new wells; 2. The relative contribution of each source is known to vary with seasonal conditions; significant pumping of the municipal well s is required only during the summer and fall months to supplement the springs. The hydraulic transmissivity T2 of the Unit 2 aquifer system 7. Later, in response to EPA comments, two surface water and sediment samples were collected from the perennial stream to the east of Route Figure 9. Future iterations should simplify the pro- cedure to individuate the necessary level of protection within the WHPA if soil protection capacity is directly included in the aquifer vuln erability assessment.

G valuethe lithological characteristics and the degree of consolida- tion of the vadose zone or confining layers i. The thickness of the residuum was found to be highly variable, raging from 10 to 80 feet.

The cases were dipped in the tank and staged in the vicinity of the tank to dry prior to applying the insulation. Pettit and B. Municipal Water Supply1 3.

The results of the analyses indicate that no active subsurface source exists north of the BES plant. However, for this method to be accepted for broad ap- plication, additio nal refinement is needed in certain areas. The material grades into bedrock and, as such, retains much of the relict structure e.
