A local pump & tank contractor teamed up with a reputable environmental consultant for a large(r) dewatering and processing contract. Process flows of 50 GPM and high VOC’s meant 600# of Granular Activated Carbon (GAC) per day, plus the labor. You do the math.
We suggested air stripping prior to GAC, with a calculated efficiency of 95%; ie. the carbon will last 20X longer. The reduced material & labor costs have MORE THAN paid for the rental / permitting / oversight / sampling for the project.
The client (as of this date) is please as more than 200,000 gallons have been pumped in April and no GAC changeouts have been required (based on samples from the primary GAC).
The tank-crew is pleased since the job is proceeding; the consultant is pleased as the on-site services are cleaner and more profitable; ReRem is pleased to add value and reason to the job.

Wednesday, December 30th, 2009Many environmental remediation projects can be quickly implemented and dynamically-scaled using a phased technology and capacity approach. Typically, initial response requires large, high-capacity technologies during the ER / Investigation / Interim Solution period of the project. As the concentrations and areal extent are delineated and attenuated smaller, more specialized equipment is deployed.
This is where ReRem can help. Our warehouses contain a variety of commonly required remediation technologies and hardware, ready to go. We can save your client the lead-time and capital-expense of short-term hardware. The consultant can address the issue while we provide the horsepower for the initial mass-removal, then de-escalate as the equipment needs change.
This prompt response can save the RP through plume minimization and initial equipment costs. It aids the consultant in providing time for a thorough investigation and proper long-term system design. WIN-WIN.
Construction dewatering
Tuesday, December 1st, 2009Tank installers commonly encounter ‘high water’ during the UST upgrade process. Removal of the groundwater is required to proceed with the project. In some cases the groundwater is ‘clean’ and discharge is authorized to a storm or municipal sanitary sewer system. In most cases the tank pit water is contaminated with Volatile Organic Compounds (VOC’s), sometimes dissolved and sometimes free-phase.
Field crews will commonly underestimate the water volume and its infiltration rate. Tanker trucks are a typical (and costly) solution to the problem. On-site treatment is a less costly remedy for quantities in excess of 10,000 gallons.
With proper planning the installers or consultant can reduce costs, increase margin and maintain the schedule. Sampling, regulatory approval and permitting good for everybody. By staging the liquids in a frac-tank (BAKER), samples are analyzed and proper treatment may be applied. Discharge as clean water saves time and money.
