However, we recommend that grab groundwater samples be collected from the <br /> excavation in lieu of collecting soil samples from the excavation floor. The groundwater <br /> samples should be analyzed for the same chemical suite as the confirmation soil samples. A <br /> letter concurring with your 7/25/06 work plan was mailed today. <br /> xegards, <br /> Mark W.

As the current excavation extends to the water table, LFR plans to <br /> collect samples from excavation sidewalls approximately midway between the <br /> bottom of the excavation and ground surface on 20-foot spacings. At each <br /> sidewall sampling location, a single soil sample will be collected in <br /> 2-inch-diameter brass liners and advanced using a slide-hammer. <br /> In addition to the sidewall samples, two additional soil samples will be <br /> collected from the floor of the excavation near the northern and southern <br /> limits of the dig area. However, due to the shallow nature of groundwater <br /> beneath the site, these soil samples should not be considered an accurate <br /> assessment of recent impacts to soil. At this time, LFR does not plan to <br /> continue further excavation into soil beneath the water table. <br /> Please contact me with any questions you may have regarding these issues. <br /> Thank you, <br /> Jeremy J.
