pond. The adsorptive reactor units are positioned close to the barrier. Each
reactor was placed in a drilled shaft, 9 ft in diameter and 26-30 ft deep. The
reactor bodies were made of cylindrical glass fiber-fortified synthetic mate-
rial equipped with filter screens. Each reactor was loaded with approx. 350-
420 ft

of GAC. The contaminated water enters the reactor through the filter
screens, passes through the column reactor, and is collected at its bottom.
