R.E.A. personnel have managed numerous hydrogeologic investigations in various geologic settings. Responsibilities have included overall project planning, negotiations with State agencies, implementation of field investi-gations, data interpretation, and report preparation. Hydrogeologic investigations have involved:
Contaminant Fate & Transport in Overburden and Bedrock;
Fracture Trace Analyses;
Soil & Water Sampling;
Mapping and Resource Evaluation; and
Water Quality Assessments
Contaminated Soil Management
During a Phase I ESA for a real estate transaction, R.E.A. discovered the location of former USTs. Subsequent investigation identified petroleum contamination above State guidelines. R.E.A. was able to quickly make arrangements for soil excavation and off-site disposal. All of the work was completed with VT DEC approval and met all of the deadlines for assisting our client with completing the sale of the property.
Phase I & II Environmental Site Assessments
The Phase I site inspection identified good housekeeping practices and proper hazardous waste storage, but noted the presence of several floor drains that were connected to the on-site septic system. The subsurface investigation conducted adjacent to the on-site septic system indentified low concentrations of solvents and metals in groundwater. R.E.A. worked with the client and VT DEC site manager to develop a corrective action plan, which included permanently sealing the floor drains and implementing monitored natural attenuation to track the degradation of contaminants in groundwater beneath the site.
Brownfields Corrective Action
R.E.A. was selected as the Qualified Environmental Professional (QEP) to develop and implement a Corrective Action Plan (CAP) at an historic abandoned railroad engine house located in north-central Vermont. R.E.A. was responsible for developing a plan to address petroleum, solvent and PAH contamination discovered in surface soils surrounding the building as well as interior building and vapor intrusion issues. The selected remedy included the installation of a geo-textile, soil and vegetative cover over four acres.
