Blue Rock also serves clients during property transactions or refinancing by performing Phase I or Phase II site assessments. Phase I work is conducted in strict accordance with ASTM guidance document E1527-05. Phase I investigations are aimed at identifying potential recognized environmental conditions at the site or adjacent sites. This is accomplished by review of environmental government databases, historical use evaluation, aerial photographs, fire insurance maps, site inspection, owner/tenant interviews, and title searches. If information obtained during the Phase I suggests a potential recognized condition, Blue Rock may recommend a Phase II subsurface investigation. Phase II activities are similar in nature to the Soil and Groundwater Investigations described in the section above, and they focus on evaluating only the potential recognized environmental condition and nothing else.
Blue Rock professionals have performed and supervised a wide variety of subsurface investigations. Our staff is adept at designing economically feasible investigation strategies that meet project goals. For subsurface investigation, a myriad of techniques are available such as (1) passive soil gas surveys, (2) traditional drilling and soil sampling, (3) cone penetrometer tests & electric logging, and (4) geophysical surveys (ground penetrating radar & magnetometers). Blue Rock endeavors to find ways to increase value of all investigation and monitoring activities, so that project costs can be reduced or redirected onto clean-up activities.
The goal of site investigation is to define the basic site parameters that will affect the selection of a remedial approach. These basic site conditions include contaminant type, contaminant distribution/magnitude, contaminant migration pathways, hydrogeological conditions, and potential sensitive receptor
Blue Rock provides technical support during litigation involving disputes over environmental responsibility. Blue Rock provides legal counsel a sound opinion regarding technical strength and weakness of data and realistic outcome of disputed site so that reasonable costs can be attributed to environmental damages.
Blue Rock principals have experience servicing small municipalities directly, or serving larger consulting firms on government projects.

Blue Rock principals have been working with the California State UST Clean-up Fund (USTCF) since it came into existence in the early 1990s. We have the experience and track record to ensure that our clients receive the maximum reimbursement of corrective action costs. Over the past 15 years, Blue Rock principals have great personal track records in managing USTCF claims for their clients.
Blue Rock can plan and conduct investigations of subsurface vapor intrusion to indoor air. A preliminary site visit would be conducted to preclude operational sources of vapors. Typically Summa cannisters would then be deployed for a regulated time collection event. The collected samples would be analyzed by a certified lab. Blue Rock would then prepare an assessment summary report.
