The complexity of cleaning up a 2.2-acre parcel of land located inside Technical Area-21 (TA-21), known as Material Disposal Area (MDA) T at Los Alamos National Laboratory could push costs as high as $1 billion, according to the Department of Energy; although no final estimate can be determined until a survey of the remediation efforts required is completed.
MDA-T is near the eastern end of DP Road. Environmental remediation activities at TA-21, including MDA-B, located across from businesses along DP Road on the southern side, have been underway since 2009.
Nearly 18 million gallons of treated and untreated plutonium wastewater and solvents, or untreated tritium wastewater and solvents, were discharged into the beds on that site until 1967.
