The purpose of this monitoring is to determine the sphere of <br /> influence produced by pulling a vacuum on existing monitoring wells. The sphere of influence <br /> will be determined by measuring the vacuum produced at other existing wells and by soil vapor <br /> probes placed around the well being evacuated. <br /> We are hoping to conduct this work on the 20 through the 22 of March. <br /> Should you have any questions or need additional information, please give me a call. <br /> Sincerely, <br /> Qhm, <br /> Senior Environmental Chemist <br /> DEO:n <br /> Attachment <br />
