Abstract: Twelve of the piezometers installed at Reid-Bedford, La., in 1949 were cleaned in 1967 by surging with water and air. On the basis of performance observations made for several days, basic time lag tests were performed on eight selected piezometers. Attempts to retrieve all 12 of the piezometers were only partially successful because of severe corrosion on the standpipes of some. Chemical tests showed that the soil was moderately acidic in the vicinity of the corroded piezometers and moderately basic in the vicinity of the noncorroded ones. The lead cable of the one electrical piezometer was short-circuited. The attempt to retrieve this piezometer failed.
