ATI Companies conducted installation, repair and replacement of Eleven (11) Monitoring Wells that included Cement Coring to access the sublayers, to monitor and remediate a deep and intermediate plume at the Orlando Executive Airport (former GOAA Dayron), and installation of Monitoring Wells at the Orlando Skate Park in Orange County, Florida. The purpose of these wells in addition to the previous Injection Wells (this project is ongoing since 2007), is to assist in assessing and remediating petroleum contaminated soil and groundwater related to releases of aviation fuel.

The current wells are replacement wells that were destroyed during the expansion construction and everyday mobility at Orlando Executive Airport. Four are delineation wells that were damaged by activity at the Orlando Executive Airport.

A GEOPROBE 7700 were used for the coring, the DPT (Direct Push Technology) Drilling and the drilling with Hollow Stem Augers (HSA’s).
