Travel, far & wide

We are (increasingly) fielding requests for pilot-test services across the eastern US, with this conversation comes the request for discounted mob and/or on-site time. While we appreciate the work from diverse clients my response is the same; three (3) consecutive days will earn you a discount mob/demob, site-time is fixed.
ReRem has entered service agreements with several large environmental engineering firms to reduce the on-site unit costs for a fixed quantity of annual work. We welcome these opportunities.

Too expensive?

Monday, January 11th, 2010

When my clients change employers I usually follow.  One such client, a VERY able and talented environmental engineer, switched companies and contacted ReRem for several feasibility studies for remediation design. The work was proposed and scheduled.  At the last minute the management cancelled the studies citing costs.

Fast forward;  this client just contacted ReRem to conduct a study at these same sites.  The equipment deployed has proven ineffective, the plume is now offsite, and two years has been lost.  The management must now explain the off-site and vapor-intrusion issues to an unhappy client.  Significant additional capital will be required to retrofit the site with an appropriate technology.

The dollars required to provide a proper study and design is less expensive than recovering trust and reputation.

Phased and progressive remediation

Wednesday, October 28th, 2009

An ‘alpha client’ contacted ReRem Equipment looking for options to address the LNAPL and VI issues in a VOC release he was managing.  A 1000-gallon release of gasoline was impacting soil, groundwater and several adjacent structures.  Drilling and investigation were on-going.

ReRem immediately deployed two (2) trailer-mounted SVE units to reduce the VI impacts on the structures, we also provided a pneumatic pumping system to depress the groundwater in the vicinity of the release.  As the plume was delineated we moved one SVE trailer to the depression well to start VEGE recovery.  During this three-week period VOC removal rates dropped by 70% and 400 gallons of LNAPL were recovered, product thickness was reduced to a ’sheen’.

Six weeks into this ER a HVE trailer was delivered and connected to the recovery well, the pneumatic pumping system and SVE trailers were removed.  As dissolved-phase constituents attenuated the need for dual-phase recovery was deemed unproductive, so the HVE trailer was removed and a small SVE skid was used to assure the VI issues were resolved.

Though rapid response and flexible treatment the consultant was able to eliminate the VI vectors, recover the NAPL, reduce the concentration of the dissolved-phase plume and de-escalate to a small SVE system.  This approach reduced the clean-up timeline, reduced the clients’ total costs, while satisfying the regulators and owners of the adjacent properties.  Well done!
