GEOTHINK conducted a Phase I HUD site investigation with JMS environmental at W. 71st St. in Chicago last Friday.

GEOTHINK conducted a Phase I ESA at Webb's Marina in Antioch on Friday, April 7th.

GEOTHINK conducted a Phase I ESA earlier this month at a carwash in Danville IL. It is one of the many services we provide. A Phase I ESA is a site visit inspection and regulatory database review (State & Federal records) of subject property and adjoining properties to identify potential “recognized environmental concerns” (RECs) that could pose environmental/business liability risk to property owner, and/or financial institution using said property as loan “collateral”. Generally, Phase I ESA follows ASTM E-1527-13 (American Society of Testing and Materials) guidelines and does not include physical sampling of the building materials, and/or soils or groundwater. Report findings recommend further investigation (Phase II ESA) or no RECs identified (no further investigation).

GEOTHINK conducted a Phase II Environmental Site Assessment at a gas station in Pontiac, Illinois yesterday.
Based on the REC findings and recommendations of the Phase I ESA report, a Phase II assessment may include physical sampling of building materials for lead, asbestos or mold testing; and/or subsurface investigation using and borings and wells to collect representative soils, groundwater or soil gas samples for lab testing for potential contaminants of concern (COCs) with the results compared to individual State cleanup limits. Phase II report identifies location(s) of testing samples contaminants above applicable regulatory limits, possible contaminant source(s) i.e. drums, USTs (underground storage tanks), ASTs (above ground storage tanks), floor drains, utility conduits and/or building materials; and provides recommendations for further investigation or mitigation/remediation of problem areas, or testing results did not identify contamination issues warranting further corrective actions.

On February 18th 2017 GEOTHINK conducted an earlier than usual prairie burn due to the warm weather. Burning the prairie removes invasive species plants. It also allows nutrients to be recycled quicker into the soils for regrowth. The success rate of reseeding is much higher after the burn.
