The folloER wing tasks detail our scope of services Task 1 —Shallow Pesticide Soil Sam Nno Kleinfelder proposes to collect a total of 8 discrete soil Will be collected in an samples at the subject site. The samples selected locations in nearby ditches oral Wel sin ver the sites a dependent on access, surface conditions and lying areas. approximately 15 acres as well as samples will be collected at de The actual sampling locations will be Potential interference with subsurface utilities. Soil surface (bgs). depths ranging from approximate) Y 2 to 8-inches below ground The soil samples will be obtained using a hand auger and slide-hanim sampling device. Hand auguring techniques are less invasive than drilling, and should be sufficient for the shallow sampling depths proposed. The hand auger will be used to advance the soil boring to the desired sampling depths. Soil samples are obtained by driving a 2-inch diameter by 6-inch long stainless steel tube into the soil using a slide hammer, forcing soil into the tube. The tube is removed from the boring and sealed with Teflon sheeting and plastic end caps. To reduce the potential for cross-contamination, downhole sampling equipment will be cleaned with a laboratory grade detergent (liquinox) followed by multiple ditilled water rinses prior to collecting each soil sample. The soil samples collected will be labeled, and placed in an iced cooler pending transportation to the analytical laboratory under chain of custody protocols. The hand auger borings will be backfilled with the soil cuttings generated during sampling. The possibility exists that hand angering and hand sampling techniques may not be successful due to hardpan soil, gravel, bedrock or peat and that different sampling methods will need to be evaluated. The eight soil samples will be submitted to a state certified analytical laboratory for the following analyses: • Organochlorine Pesticides by EPA Method 8081 • DRCP by EPA Method 8011 The samples will be analyzed on a standard 10 to 15 day turnaround time. This shallow soil sampling task is for a limited valuation of pesticides in soil at the subject site and does not reflect regulatory requirements. If regulatory agencies are going to be consulted, a more detailed sampling and analysis protocol should be conducted at this time.
