Phase II Environmental Site Assessments (ESA) may be necessary to evaluate the existence of subsurface contamination or to define the extent of known contamination.  AKT Peerless' staff is experienced in a broad range of subsurface and hydrogeologic investigation activities.

Typical investigation objectives include the following:

·         Drilling soil borings and collecting physical samples for site-specific stratigraphic characterization

·         Installing monitoring wells

·         Investigating releases from underground storage tanks (USTs)

·         Collecting soil and groundwater samples for chemical characterization

·         Surveying monitoring well elevations and locations, and obtaining static water levels

·         Estimating groundwater flow direction based on survey data

·         Evaluating contaminant concentration distribution and migration potential

AKT Peerless also conducts the following activities:

·         Geophysical surveys, including soil conductivity and resistivity surveys, total-field proton-precession magnetometer surveys

·         Aquifer pump tests

·         Aquifer slug or bailer tests

·         Groundwater and other hydraulic computer modeling

AKT Peerless conducts all investigation activities according to the American Society for Testing and Materials (ASTM), United States Environmental Protection Agency (USEPA), and State guidelines.

For example: Phase II subsurface investigations are conducted according to ASTM E1903, "Standard Guide for Phase II Environmental Site Assessment Process"; and samples are collected following USEPA Publication SW-846, testing methods for evaluating solid waste.
