REMEDIAL INVESTIGATION
If a Phase I or II Environmental Site Assessment or other information
identifies areas of a property or facility that are suspected
of having contamination, a subsurface environmental investigation
is often required. Groundwater and subsurface investigation
services provided by GHR include: site characterization, contamination
delineation, discrete depth groundwater/soil sampling, monitoring
well installation, remedial investigation and feasibility studies,
remedial action workplans, and petroleum hydrocarbon product
removal. |

REMEDIAL SYSTEM DESIGN
Through environmental remedial investigations, GHR develops
strategies for cleaning up subsurface contamination. In the
mid-Atlantic region, GHR has designed and operated dozens
of remediation systems, using a variety of cleanup technologies,
tailored to site specific conditions. GHR looks to emerging
technologies for the means to expedite the remediation of
contamination from groundwater and soils, and to complete
cleanup in the most cost effective manner. |

EMERGING TECHNOLOGIES
Innovative technologies for use with in-situ remediation
systems are integral to GHR’s design process. Some contaminated
sites that have challenging hydrogeologic characteristics
often benefit from emerging technologies such as chemical
oxidation and oxygen infusion. The use of new technologies
can expedite cleanup to meet regulatory standards, and often
lower installation and operating costs.
GHR will help evaluate clients' contaminated sites to design
and develop the most appropriate, cost effective remediation
approach. As cleanup progresses, GHR critically evaluates
test results, rather than just collecting data. By careful
analysis of results, often the treatment approach can be modified
to better focus treatment strategies to match the evolving
site’s conditions.
GHR keeps abreast of scientifically supportable emerging
technologies accepted by regulatory agencies so that sites'
remediation can be achieved more quickly and at less cost
than previously possible. Examples include: monitored natural
attenuation, enhanced managed attenuation and chemical oxidation.
