Once the liquid was drained from Basin F, the drying of the soils, sediments, and liner began. This project caused an odor resulting in discomfort to members of the surrounding community. Because of the Army's concern for the comfort of the local community during the soil drying, air purifiers were

The increased volume of liquid in Basin F caused by the heavy rainfall in May 1988 required additional storage capacity. Two double-lined holding ponds were constructed: a 5.5 million US gallons (21,000 m) pond (Pond B) and an 6.5 million US gallons (25,000 m) pond (Pond A). The

The Basin F Interim
Response Action began in March 1988 and involved the transfer by tank truck of 4 million US gallons (15,000 m) of Basin F liquid to three 1.3 million US gallons (4,900 m) holding tanks and approximately 6.5 million US gallons (25,000 m) to a

In May 1988, near the start of the project, a heavy rainfall classified as a 25-year/24-hour event occurred which increased the volume of Basin F liquid. In June 1988, a
