 Drilling Contractor setting up drill to drill to a depth of 20 feet below the concrete surface
|
 The soil and groundwater under the building was contaminated with BETX, DDT, Malathion and other pesticides
|
 Soil was cored and registered at the depth groundwater was encountered which was 16 feet
|
 The impervious layer of clay was encountered at twenty feet
|
 Soil cores were sampled at every four feet to determine scope of contamination
|
 4
4"holes were drilled after core sampling was completed.
|
 OSEI Corp. puts in monitoring wells so that continuing sampling is possible, and so OSE II can be applied
|
 5 drums of OSE II were set up on a slow continuous feed into the monitoring wells
|
 OSE II was applied by a continuous slow feed because the wells could only take in so much liquid for a given time period
|
 In less than 30 days the groundwater and soil under the building were reduced to acceptable cleanup levels
