Superfund Record of Decision: (EPA Region 6): ATSF (Atchison, Topeka and Santa Fe) Site, Clovis, New Mexico (First Remedial Action), September 1988

摘要

The Atchison/Santa Fe (Clovis) Superfund site is located just south of the Atchison, Topeka and Santa Fe (ATSF) Railway switching yard in Clovis, New Mexico. The site is comprised of an approximately 26-acre playa lake (Santa Fe Lake) which has been owned by ATSF since the early 1900s. The lake was used for the disposal of wastewater from various operations throughout the years. Wastewater from the washing of hopper cars used for hauling potash, cement, fertilizer, grain, and coke were disposed in the lake from 1962 to 1982. The primary contaminants of concern affecting the sediments, soil, surface water, and ground water are metals including arsenic, chromium and lead, organics including phenols and inorganics. The selected remedial action for the site includes: construction of a run-on control dike and ditch system; evaporation of the water in Santa Fe Lake through a pump and spray sprinkler system.
