Dear Mr. Miller: At your request, Stratus personnel visited the subject site on March 5, 2004, to observe and document the condition of the monitoring wells. At each well location, the well box and watertight plug were inspected, and conditions inside the well box documented. Due to traffic conditions at the time of our visit, off-site wells MW4, MW-5, MW-6, and MW-8 could not be safely accessed. Well MW-1: Concrete around the well box is intact. Water not observed inside the well box. Well cap appeared tight, and lock was in place. Able to tighten bolts when securing lid. (Photos 1 and 2) Well MW-2: Concrete around the well box is intact. Approximately 1 inch of water observed standing inside the well box. Well cap appeared tight, and lock was in place. Able to tighten one bolt to secure lid, but one of the tabs is broken, and the second bold cannot be secured. (Photo 3) Well MW-3: Concrete around the well box is intact, but there were no bolts securing the lid. Approximately 1 to 1'/2 inches of watery mud were found inside the well box. Well cap was locked but did not appear to be tight. Muddy smudges were observed on the inside of the casing, suggesting that some mud and water may have entered the well casing. Asphalt and concrete pavement in vicinity of the well is badly damaged. (Photos 4 and 5) Well MW-7: Concrete around the well box appeared intact. No water observed standing inside the well box. Well cap appeared tight, and lock was in place. Able to tighten bolts when securing lid. (Photos 6 and 7)
