Monitoring and remediation

Our monitoring and remediation staff offers a variety of field-based services including water, soil, and air testing. We are experienced in water sampling on coal mine sites and air and water monitoring near non-conventional gas well developments. We also offer expert testimony in court cases, litigation support, risk assessments, and site characterization.

Project spotlight

Watershed-Based Plan Sampling

Watershed-based plans are invaluable tools for identifying pollution sources and addressing water quality issues within a watershed. In support of a watershed-based plan for local nonprofit Friends of Deckers Creek, Downstream Strategies staff collected in-stream water samples and field data at approximately 70 sites throughout the Deckers Creek Watershed. In-stream water samples were collected for analysis of general chemistry and metals parameters while field measurements were collected to determine in-stream temperature, pH, conductivity, and dissolved oxygen levels.

Oil and gas pollution monitoring on private residential property


We have performed targeted sampling programs and a detailed technical review of site characterization data for a release of oil and gas related fluids from a temporary storage impoundment on a private residential property. This work has provided the basis for property owner negotiations with the operator and regulatory agencies to restore drinking water and soil quality at the site.

Our approach


During commercial real estate transactions, evaluation of environmental conditions is often critical to determining value and potential liabilities associated with a property. We offer environmental due diligence services ranging from those completed to the ASTM 1527-2005 standard seeking liability protections afforded under EPA's Superfund Law (CERCLA), to client-customized approaches for developing independent professional opinions about the environmental conditions of a property.
