ASTM E1903 (Standard Guide for Phase II Environmental Site Assessments)

ASTM E1903 is a standard guide that outlines the process for conducting Phase II Environmental Site Assessments (ESAs). These assessments are crucial for evaluating potential contamination of properties, especially when they're being bought, sold, or developed. Phase II ESAs involve collecting soil, groundwater, and other samples to test for pollutants, following a Phase I ESA which identifies potential issues. The guide helps professionals determine the scope and methodology for testing, ensuring thorough and reliable results to inform decision-making and mitigate environmental risks.
