AESCO, Inc. P2732 Statement of Qualifications drilling technique provides a continuous casing as the boring advances, minimizing cross contamination or mixing of upper zones of soil and groundwater with lower zones. Environmental Site Assessments The potential liabilities associated with the presence of hazardous substances on a property can be substantially greater than the value of the property itself. Environmental laws and court decisions have increased the risk of liability for lenders as well as for buyers, sellers and operators of property. AESCO assists clients in making critical, timely and economically sound decisions on property management and ownership transfers. Our Environmental Site Assessment (ESA) services are offered in phases to provide maximum benefits in the most cost effective manner. Phase I The purpose of the Phase I ESA is to identify any obvious concerns for potential environmental impairment. The scope of work consists of the following activities: • Determine the existing site conditions: complete a comprehensive visual walk- through examination of the site. • Review the site history: collect historic maps, photographs and directories; examine aerial photographs and title abstracts, and interview persons familiar with the site (e.g., former owners, occupants, workers, neighbors). + Evaluate physical setting information: topography, soil conditions, site geology, regional ground water conditions, and floodplain and zoning information. • Visually examine surrounding land use: research surrounding properties for present and past activities that may affect environmental suitability. • Regulatory review: inquire of appropriate local, state, and federal agencies to identify environmental concerns. • Prepare Phase I report: evaluate all data and prepare an opinion and/or conclusions stating that either the site has minimum probability for environmental concern, or that the assessment has led to questions regarding environmental suitability. If potential environmental liabilities are identified, recommendations are made for additional activities, including possible Phase II investigation. Phase II Environmental Analysis The Phase II environmental analysis commonly consists of subsurface exploration to obtain samples and analysis of soil and/or groundwater samples for the presence of hazardous substances or petroleum products. AESCO's typical approach to a Phase 11 ESA includes: Preparation of a site-specific sampling and analysis plan to confirm the extent and concentrations of contamination in accordance with the EPA standards and local, State, and federal guidelines. • Preparation of a site-specific health and safety plan. • Sample collection of waste, waste streams, hazardous materials, surface water, groundwater, soils, asbestos, or other material samples, and the testing of underground storage tanks for content and structural integrity. • Comprehensive review of the regional and local geology and hydrogeology to determine Civil Engineering/ Inspection ?
