– City of Denver/Waste Management Inc. – Operated as a municipal landfill prior to its designation as an *NPL site – Accepted solid and liquid industrial hazardous wastes (estimated 138
million gallons of hazardous substances disposed at site) – Selected remedy involves containment and treatment of hazardous substances *NPL – National Priorities List
1966 – 1980: Landfill accepted liquid and solid industrial wastes 1984: Designated Superfund Site
6 Operable Units(OUs)
OUs 1 and 6: shallow groundwater, subsurface liquids, and deep groundwater
(ongoing);
OUs 2 and 3: landfill solids and gas and OUs 4 and 5: soils, surface water and sediments
1984 – 1993 : Evaluation of remedial alternatives 1994: Record of Decision issued (Containment) 1997: Construction of remedy
2003: Contaminant 1,4‐dioxane discovered in shallow
2003‐2007: Investigation conducted to delineate extent
2006 ‐ present: Contingency operations
Currently: Technical evaluations completed/underway
4rd FYR underway
required every 5 years to ensure protectiveness of human health and the
environment is maintained throughout the life of cleanup
Considers changes in conditions/technologies over time that may impact or
improve cleanup goals
Ongoing technical evaluation of groundwater remedy effectiveness
Are remedy components functioning as intended? Is there a growth fault bisecting the site that may provide a migration
pathway?
Does injection of potable water influence contaminate concentrations? Is the statistical model used to determine groundwater compliance reliable? Is the extent of the plume fully delineated? Are extraction wells effectively providing capture of contaminants? Is the 1,4‐dioxane plume residual in nature or an indication of remedy
bypass?
Are contingency activities effectively mitigating the north end plume?
