Subject: Westlake Landfill
Westlake Landfill, located in Bridgeton Missouri (St. Louis County) has been
the subject of recent inquiry. This landfill began operation prior to state
regulation. As far as our records show, this landfill first opened in the
mid-1960’s. Part of the landfill lies in an old quarry and part of the landfill
lies in the Missouri River floodplain, approximately 1^ miles from the
river. Witnesses to this operation, when the area of the landfill which lies
in the floodplain was in operation, note that the fill area was often actually
beneath the level of the water table. According to file materials from
Missouri Geological Survey, it is “highly probable that leachate from the
landfill is entering the waters of the Missouri River. . . ” Leachate from
the old quarry area of the landfill is collected and hauled to MSB treatment
plants. Construction of onsite treatment facilities is underway. About 48,000
gallons of leachate per day is currently being collected.
Aside from normal landfill materials, there are chemical industrial wastes and
radiologically contaminated materials deposited in this landfill. The chemical
wastes, that we know of, include about 4,000 tons of residues from the production
of insecticides and herbicides. These pesticide wastes were deposited by
Chevron Chemical Company. Also included in the chemical wastes are waste
materials from ink manufacture and from the manufacture of glue. Among the
chemical wastes that we know of in Westlake Landfill are:
waste ink pigments
esters alcohols
halogenated intermediates
oils wastewater sludges
heavy metals asbestos
oily sludges
insecticides
aromatics
herbidices

Besides chemical hazardous wastes, in Westlake Landfill, there are radioactive
wastes. During early 1973 Cotter Corporation buried radioactive Barium
Sulfate Slag material and radiologically contaminated building rubble. There
are approximately 9,000 tons of this material which contain about 7,000″tons
of natural Uranium. In October, 1977, an aerial radiological survey was done to
determine the location of the burial of this contaminated material. The report
from this survey indicates that there are two burial sites. One is in the
center of the old quarry area, and the other is on the edge of the floodplain
area which borders adjacent farmland. The U.S Nuclear Regulatory Commission
has contracted Radiation Management Corporation to do extensive on-site
radiological surveys which include groundwater analysis, core sampling, test
boring, and other tests as deemed necessary. The NRC has given DNR verbal

permission to utilize the monitoring wells which Radiation Management
Corporation will be digging, in order that DNR may test for the presence of
chemical hazardous wastes.
There is little known about what went into Westlake Landfill prior to State
regulation. Analysis needs to be done to determine: 1) what wastes are
deposited in Westlake Landfill, 2) if any of these pollutants are leaving
the landfill via groundwater, and 3) what threat does Westlake Landfill pose
to drinking water supplies.
