PROPOSED GROUND WATER INVESTIGATION Based on proposals received from three local consulting firms three ground water monitoring wells would be installed in order to confirm the absence or presence of contamination of the ground water at this site and to determine the ground-water gradient and assess the lateral extent of possible dissolved hydrocarbons. Three eight inch diameter borings would be made located beyond the estimated lateral limits of capillary fringe zone contamination which would be determined by approximately 5 soil borings drilled laterally from the existing monitoring well on-site. The drill augers will be steam cleaned between borings . Soil samples will be collected and classified at 5-foot intervals with a field OVA with at least. one sample from each boring being sealed with Teflon film, capped, labeled, and chilled for transport for analysis at a state certified laboratory. Soil samples from the well drillings will be collected at 5 foot intervals and retained for possible laboratory analysis with one sample from each in the capillary fringe zone being transported for analysis of total petroleum hydrocarbons (TPH) , purgeable aromatic hydrocarbons (BTEM and total lead in accordance with the appropriate EPA approved methods. The wells will extend 20 feet into the groundwater to a total anticipated depth of 115 feet below grade. The well excavations will be cased with slotted two-inch diameter PVC casing, and appropriate filter pack sand, installed from the bottom of the borings to ten feet above first groundwater. Blank PVC casing will extend from the surface down to the well screen. A 3 foot thick betonite seal will be placed above the filter pack with the remaining upper annuli sealed with a sand-cement-bentonite slurry. Drill cuttings, sample spoils and water produced on site will be stored separately in D.O.T. approved 55-gallon labeled drums on site. Following laboratory analysis appropriate disposal methods will be proposed. The monitoring wells will be developed by surging and the removal of a minimum of three well bore volumes of water. The well heads will be surveyed to a common datum and the water level in each well measured to an accuracy of 0.01 feet so that a state certified land surveyor may accurately determine the site-specific groundwater gradient and flow direction. Following purging, groundwater samples will be collected with a Teflon bailer and handled in accordance with EPA protocol for .transportation to a state certified laboratory for analysis for TPH, BTE&X and total lead. All work will be completed in a manner consistent with the level of care and skill ordinarily exercised by professional environmental consultants . Upon formal contracting with a consulting firm to complete the above outlined work, a more detailed work plan will be submitted for approval prior to seeking the groundwater well permits.
