POND A NEUTRALIZATION AREA, SFAAP-005
SITE DESCRIPTION
The Pond A acid neutralization unit is located
on the southeast edge of the pond. It
was constructed in 1942/43 to treat the acidic
wastewater flowing into Pond A from the
NC area and had two periods of operation:
1942 - 1950 and 1952 - 1960 (DM, 1989;
PRC, 1990). The pH of the Pond A effluent
was adjusted in the neutralization unit
before draining into Pond B (SWMU 6).
Neutralized wastes and unsettled flocculent
were discharged to an open drainage ditch
leading to Pond B (DM, 1989; PRC, 1990).
During a visual inspection in 1990 a white
sludge identified as “pebble lime” was piled
up along the southeast edge of the plant.
Initial RFI data indicates elevated levels of
metals in GW and elevated levels of nitrocellulose
in soil.
