Property Transactions/Due Diligence (Phase I Environmental Site Assessments)
GLE’s staff has performed thousands of Phase I Environmental Site Assessments in accordance with ASTM E-1527 for numerous clients including commercial lenders, private land owners, and municipalities. Our safety health environmental management staff are experts in the evaluation of a properties environmental health and safety for acquisition by our clients, and we can complete a Phase I Environmental Site Assessment Report, to your specific requirements within 5 working days.

Each Phase I Environmental Site Assessment prepared by GLE includes the following:

• Site condition evaluations
• Evaluations of past site use and operational practices
• Property title searches (if required)
• Tenant records and archive researches
• Aerial photos, site maps and plan reviews
• Interviews with previous owners
• Construction records
• Environmental regulatory searches
• Current commercial & industrial operations
• Inventory of on-site hazardous materials, records & MSDS
• Review of environmental files and permits
• Sanborn maps (if available)
• Evaluation of various environmental transport routes

Phase II Environmental Site Assessments
Should a recognized environmental condition (REC) be identified that affects the environmental health and safety of your site or property, GLE’s safety health environmental management staff will prepare a scope of work to address the potential for soil & groundwater impacts, implement the scope, and prepare a Phase II Environmental Site Assessment report in accordance with ASTM E-1903-97 standards which will include many of the following services:

• Development of testing programs
• Site explorations using soil borings (DPT)
• Excavation of test pits
• Collection and sampling soil, surface water and groundwater
• Installation of groundwater monitoring wells
• Sampling and identification of potentially hazardous waste
• Sampling of liquid and sediment in streams, ditches, ponds and surface runoff
• Sampling suspect areas of past spills
• Soil vapor surveys and monitoring
• Geophysical investigations
• Analysis of groundwater flow and contaminant transport

Each Phase II Environmental Site Assessment is unique and developed specifically to address the REC, based upon the results of the Phase I Environmental Site Assessment and the site-specific investigation constraints (utilities locations, building locations, etc.). Once the Phase II Environmental Site Assessment is completed, GLE will determine if the site requires further investigation or if there is no basis for further investigation or remedial action.

Assessment/Remediation Services
GLE’s offices are staffed with a safety health environmental management team that consists of professional engineers, geologists and senior scientists, who have considerable experience in the assessment of property impacts (e.g. petroleum, solvents), environmental health and safety, identification, evaluation and selection of remediation treatment technologies (e.g. Excavation, air-sparge/soil vapor extraction (AS/SVE), Dual-Phase Extraction (DPE), Multi-phase Extraction (MPE), land farming, soil washing and/or Bioremediation) for cleanup of a facility. GLE can provide the following environmental site assessment and cleanup services:

• Site assessments and SAR preparation
• Remedial action plan preparation (LSRAPs and Full RAP Preparation)
• Bid package preparation and bidding services
• Contract preparation and negotiation
• Remediation system installation/construction (RAC)
• Remediation system operation & maintenance (O&M)
• Well sampling and site monitoring (PARM)
• Site reconstruction to pre-cleanup conditions

GLE’s senior engineers and geologists have vast experience, giving them the ability to easily identify whether remediation is required or if site-specific, alternative site rehabilitation levels (SRLs) may be proposed. GLE’s professional geologists and engineers have extensive experience negotiating with State (FDEP) and local environmental regulatory agencies to ensure that remedial action is taken only if necessary and appropriate. Additional environmental services GLE offers, regarding petroleum distribution systems include the following:

Closure assessments (tanks, spill buckets, sumps, dispenser liners) conducted with 24 hours notice (field work completed in 48 hours)
LCAR preparation for secondary discharges conducted within 30 days (historic and current plume size comparison conducted prior to report submittal)
SRFA agreement negotiation (contamination constituent and plume size comparisons conducted and estimated cost impact calculated prior to SRFA negotiation with FDEP)
Limited source removal initiative site cleanup with UST upgrades evaluations (FDEP funded work)
UST upgrades/remediation system installation coordination (FDEP funded work for active sites in cleanup program)
