Environmental Site
Assessment
Phase I & II ESAs that protect your investment.
Coastal Testing Laboratories provides comprehensive Environmental Site Assessment (ESA) services to help clients evaluate environmental conditions prior to property acquisition, development, or redevelopment.
Core Environmental Services
We prepare Phase I Environmental Site Assessments in general accordance with ASTM E1527-21, through site reconnaissance, records research, and interviews. If a Phase I identifies recognized environmental conditions, our Phase II assessments use subsurface sampling and laboratory testing to define them, so commercial, industrial, and municipal clients can make informed decisions.
Phase I ESAs
Due Diligence
We provide rigorous due diligence in accordance with ASTM E1527-21 to identify Recognized Environmental Conditions (RECs) before you close on a property.
Phase II ESAs
Subsurface Testing
When potential risks are identified, our team moves quickly to perform targeted subsurface sampling and laboratory analysis following ASTM E1903-19 standards.
Regulatory Compliance & Support
We guide clients through complex environmental regulations, providing the documentation and support needed for property transfers, redevelopment, and compliance.
