Soil impact starts near 12 feet below grade. <br /> The observation well(s) at 25 feet from the DPE well, would have a construction with the same depth and <br /> screen length (15 to 45 feet), as the proposed DPE well; this would expose the OB screen to soil vapor and <br /> get accurate readings from ground water. <br /> A third well for observation could be installed 40 feet away from the DPE well and service the pilot test well; to <br /> a point were AGE can state with high level of assurance that DPE (soil vapor and HV ground water extraction) <br /> will be effective at X feet radius. <br /> Let me know if three wells are OK and AGE will get the package (check+forms) to your office. <br /> Thank you in advance for your help in this matter.
