Show and the Magna Rail Car Shop. As a result, sample density may be higher than normal and fill and post reclamation sampling may occur concurrently with post removal sampling. Post removal samples will be collected as an area is exposed. Generally, samples will be composites arranged in a linear manner trending east to west (across slope). Sample subsites will be spaced between 25 to 50 feet apart. If exposed soil varies in texture, color or content, grab samples may be collected to isolate different materials. Post reclamation samples will be collected after regrading of the slope is complete and fill soil has been placed. Samples \Yill be composites arranged in a linear manner trending east to \vest and subsites will be spaced betv,:een 25 to 50 feet apart. Fill soil samples will be collected periodically as soil is delivered to the Site. One sample will be collected for every 5000 cubic yards hauled to the Site. The samples vvill be collected from stockpiled soil prior to placement, and will be composites consisting of five subsites collected from random locations around the stockpile. ANALYSIS All samples will be analyzed for total arsenic, cadmium, lead and selenium concentrations using Environmenta l Protection Agency (EPA) Methods 3050 (preparation) and 6010 (analytical/ICP). Post removal samples will be analyzed for leachable (SPLP) arsenic, barium, cadmium, chromium, lead, mercury, selenium and silver concentrations. MO I padde.wpd* 2 June I 0, 1997 Rev . 0 |
