Site Investigations and Remediation

Walden performs investigations to characterize soil, soil vapor, and groundwater conditions at sites ranging from small fuel spills to RCRA and Superfund sites.  At Walden, we tailor investigations based on site characteristics and project objectives to ensure a cost-effective approach.  Walden’s professionals also perform Phase I/II Environmental Site Assessments for due diligence to protect clients from taking on onerous environmental liabilities during property transactions.  After the nature and extent of contamination at a site are defined, Walden develops a Remedial Action Plan describing the recommended remediation option, representing the most appropriate alternative to achieve the objectives in a cost-effective manner.  Walden has the expertise to effectively and efficiently fulfill your site investigation and remediation needs.
