environmental site assessments (esa): Phase I,ii&iii


SIGMA assists clients in making critical, timely and economically sound decisions on property management and ownership transfers. Our Environmental Site Assessment (ESA) services are offered in phases to provide maximum benefits in the most cost effective manner.

Phase I:

-Site reconnaissance to view existing conditions on the property and surrounding land use.

-Review the site history using a variety of sources including aerial photos.

-Evaluate the site geology, soil conditions and topography.

-Review local, state and federal agencies to identify environmental concerns in the vicinitys



Phase II:

Phase II investigation consists of material sampling to confirm or deny the presence of hazardous substances or petroleum products. SIGMA personnel will collect if necessary soil, ground water, waste streams, and hazardous materials that are submitted for laboratory analysis.

Phase III:

This will involve the development of a remediation program. SIGMA provides technical and economic analysis of remediation plans and evaluates alternatives to ensure cost-effective implementation of the remediation program. SIGMA’s remediation services include project design, project management, regulatory agency coordination, project documentation and reporting.
