project pic 15

Appanoose County Site in Centerville, Iowa was a former gas station and was located next to a creek and within 200 feet of a drinking water well.  Floating free product was identified in several monitoring wells as well as petroleum sheen on the creek water.  In addition, several residential buildings with basements were identified within 300 feet radius of the site.  SHEKAR investigated the extent of soil and groundwater contamination and completed a RBCA Tier-2 report.  SHEKAR also developed a corrective action design to remove free product and remediate both soil and groundwater contamination.  The on-site building was demolished; existing tanks were removed and disposed; the contaminated soil was excavated and hauled to a landfarm site.  The extent and depth of excavation was decided by taking headspace readings using a PID and confirmed by laboratory analysis of soil samples.  The site was backfilled with clean dirt and restored to original grades.  Several monitoring wells were installed after the completion of the corrective action.  Groundwater monitoring results indicated significant reduction in contaminant concentrations.

Petropoint, a gas station at the intersection of Hickman and 100th Street in Urbandale, Iowa lost 1,300 gallons of gasoline due to a loose fitting. SHEKAR was retained to remove free product as quickly as possible to mitigate environmental impact.  SHEKAR personnel pumped approximately 600 gallons of free product using the leak detection wells that were located around the tank pit.  A low volume pumping was continued to prevent contamination migration.  A soil vapor extraction system with several extraction wells was installed around and in the tank pit.  The entire system was installed within 3-days.  SHEKAR successfully removed 1,300 gallons of free product within 3-months and prevented migration of contaminants off-site.
