Bill Schalliol February 2, 2008 Page 2 of 5 PROPOSED SCOPE OF SERVICES WPI will begin the site investigations by attempting to confirm whether the interior floor drains are connected to the City of South Bend's municipal sewer system. WPI will place the dye tablets in the floor drains and direct a large amount of water into the lines. WPI will attempt to verify the municipal connection by looking for the dye in the nearby sewer manholes. If the drains connection to the municipal sewer system is not verified, WPI will recommend an additional soil boring in the vicinity of the drain. Due to the unknown location and status of the underground storage tanks, WPI proposes to conduct a ground penetrating radar (GPR) survey on certain areas of the subject properties. This survey will be utilized to determine whether or not any tanks are still present, and help pinpoint sample locations by potentially finding exact past locations of previously removed tanks. If any tanks are still present, WPI recommends that the tanks be removed from the ground according to all applicable regulations. A sampling plan for the remainder of the area may be modified once the GPR survey is complete. WPI will verbally report the findings of the GPR to the City. The soil and groundwater samples will be obtained by using a Geoprobe unit. The Geoprobe is a truck-mounted, hydraulically activated sampling device that pushes a probe into the ground at approximately four-foot intervals. Pushing of the probe can proceed to any desired depth at which soil and/or groundwater samples can be collected. The soil samples will be initially scanned using a Photoionization Detector (PID). Each Geoprobe location will be converted into a temporary well for the purpose of collecting a groundwater sample from the upper portion of the saturated zone. The collection of groundwater samples from the upper portion of the saturated zone. The collection of groundwater samples will involve the insertion of a 1-inch PVC slotted screen and riser into the borehole created by the Geoprobe. Once inserted, WPI will attempt to place a sand filter around the PVC screen to assist in the filtering of suspended solids. A minimum of five well volumes of groundwater will be removed from the well prior to initiating sampling. Once the groundwater sample has been collected, the well will be allowed to recharge and a measurement of the depth to groundwater will be noted. Soil and groundwater samples will be submitted to the laboratory for analysis of suspected potential contaminants. WPI will coordinate with the utility location services to ensure that the proposed boring locations are not located near any utilities. The drums of hazardous or petroleum waste cited in the Phase I ESA reports will be further investigated and properly disposed of according to the Indiana Department of Environmental Management and the Environmental Protection Agency's requirements if the site owners will not remove them. WPI will contact the City with a disposal plan once the drums have been assessed. REPORTING Upon completion of the field and laboratory work, a final report shall be prepared for your review, comment and approval. The report shall include a site plan showing soil boring locations, soil boring logs showing the classification of the subsurface materials encountered and conditions of the soil, analytical results and our findings and conclusions regarding the site. QUALIFICATIONS Cost estimates for our proposed services have been prepared based on the following assumptions: • WPI will have unlimited access to the site during daylight hours, • WPI will have access to a water source for the floor drain dye testing
