Phase I and II Investigations
Since 1985, BASELINE has conducted more than 300 Phase I and Phase II Environmental Site Assessments for our clients. We have performed site assessments for residential, commercial, industrial, and agricultural properties throughout Northern California. All of our Phase I site assessments are performed by senior environmental professionals and meet or exceed ASTM standards and AAI requirements. Based on the findings of an assessment, BASELINE can recommend creative solutions to match your project needs and risk management profile. We have also performed numerous Initial Site Assessments (ISAs) and Preliminary Site Investigations (PSIs) for transportation projects in California in conformance with Caltrans guidance documents. For Phase II and PSI projects we investigate the presence of contaminants in soil and groundwater, including aerially-deposited lead assessments.
