HANA has been performing site assessments/investigations for over 20 years in California. Key personnel have even more experience approaching 35 years. We are very experienced in the process of evaluating properties that may have been impacted with known or suspected regulated or hazardous materials. Our professional staff of scientists fully understand the requirements of Phase I Environmental Site Assessments. We have performed numerous Phase II site investigations/characterizations of properties ranging from small corner gasoline stations and dry cleaning businesses, metal plating facilities, large industrial/manufacturing facilities, to full scale petroleum refinery closure. HANA’s professional geologists and environmental scientists have the knowledge, experience and capability to successfully plan and implement site assessment/investigation programs that are efficient, cost effective, and acceptable to California’s regulatory agencies. This is keeping with our mission to provide responsive, affordable, and results-oriented environmental services that exceed our client’s expectations.
