This latest edition, available in print or CD-ROM, contains 22 ASTM guides, practices, and test methods, all of which address important elements of the Phase II environmental site assessment process. The standards cover many of the routine, day-to-day procedures and terminology used in properly evaluating a site to determine the presence or absence of environmental contamination, including the following:

• Conceptualizing subsurface and contaminant conditions to adequately focus subsurface investigations

• Selecting and using drilling and soil sampling techniques

• Classifying and describing soils

• Designing and installing groundwater monitoring wells

• Sampling and monitoring groundwater, including direct-push equipment

• Soil gas monitoring

It includes E1903 itself, the Standard Guide for Environmental Site Assessments: Phase II Environmental Site Assessment Process. This is a key standard for environmental assessments for commercial real estate; it picks up where the seminal due diligence standard leaves off. Also included is the newly revised E1527 Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process
