Brennan Environmental, Inc. performs soil, groundwater, and indoor ambient air investigations for both residential and commercial clients to determine whether contamination is present. If contamination is present Brennan Environmental, Inc. performs delineation services to determine the source and boundaries of the contamination and then develops the most cost efficient solution to clean up the site as quickly and efficiently as possible. Brennan Environmental, Inc. has been on the leading edge of in-situ chemical oxidation solutions, which in many instances is a significantly more cost-effective solution in situations which would otherwise require significant structural support and specialized excavation. As of April 2010 Brennan Environmental, Inc. has completed 8 in-situ remediation events and receiving No Further Action letters on 4. The remaining 4 events are either in post-remediation monitoring or active events.
