GE GENESIS ENGINEERING& REDEVELOPMENT 4. Advancing a boring to the bottom of the shallow water bearing unit, estimated to be approximately 60 feet bgs,and installing an 6-inch diameter pump test well. Soil samples will be collected from the boring at approximate depths of 1 foot, 5 feet, 10 feet, 15 feet, 20 feet, 25 feet, 30 feet, 35 feet, 40 feet,45 feet, 50 feet, 55 feet, and 60 feet bgs. Soil type will be logged for each boring. A groundwater sample will be collected from the test well following well development. 5. Analyzing all soil and groundwater samples for nitrate and ammonium. 6. Analyzing select soil samples for permeability. 7. Analyzing select water samples for nitrogen isotope rations and tritium. 2.2 Site Reconnaissance, Preparation,and Restoration A Site reconnaissance will be conducted to locate and mark the boring locations. Boring locations in areas with soil or vegetative ground surface will be marked using wooden survey stakes. Boring locations in paved areas will be marked using surveying paint. The boring locations shall also be evaluated for access routes. Site preparation will include clearing the proposed boring locations of underground utilities and other obstructions for subsurface activities. The proposed boring locations may be adjusted based on the results of the subsurface survey. Upon completion of field sampling activities, disturbed areas will be restored to a level that, as closely as practical, approximates the conditions at the beginning of the field work. 2.3 Drilling and Logging Techniques All drilling activities shall conform to state and local regulations and shall be supervised by a Licensed Geologist. The following procedures shall be followed during the drilling of exploratory borings and collection of subsurface soil and groundwater samples. • Drilling and sampling equipment shall be decontaminated as described in Section 2.4 Ripon Farm Services,Inc. 2 of 15 Sampling and Analysis Plan July 2009
