Ricker Plume Stability Method™
If you feel that consultants are managing your site as an annuity instead of a problem needing resolution, take a moment to learn about EarthCon's Ricker Plume Stability Method™. The Ricker Method® was born out of a client's need to answer a simple question – is my plume stable or is it shrinking? The Ricker Plume Stability Method™ can help you answer that question and has been accepted for use by several USEPA Regions and state regulatory agencies. Take a moment to see just one of EarthCon's success stories.
CHALLENGE An international packaging manufacturer was experiencing escalating costs to maintain their groundwater pump and treat systems which were installed in the early 1990’s. The groundwater had been impacted by pentachlorophenol (PCP) and the system consisted of 15 recovery wells. EarthCon was selected to provide groundwater remedy options to help the client stay in compliance and reduce operating costs. With no end in sight for the closure of the pump and treat system, the client was initially evaluating more source treatment options. Due to compliance issues, there was some initial reluctance on the client’s part to consider other alternatives. After EarthCon presented the scientific and defensible processes to evaluate the systems with the Ricker Plume Stability Method™ and Remediation System Benefit Analysis (RSBA®) methods, along with the success others in the industry had experienced, the client decided to move forward.
BUSINESS SOLUTION EarthCon was able to demonstrate that the pump and treat system (with annual costs of $75,000) was not impacting the remediation which was in fact occurring through natural attenuation. The findings were based upon historical information, the Ricker Method®, a RSBA®, a preliminary MNA evaluation and recent groundwater sampling data. The data analyses was presented to the State Environmental Quality Agency to demonstrate that the system was not performing adequately and groundwater could be remediated more effectively under natural conditions. The State agreed to a proposed phased shutdown of the pump and treat system, and implement a natural attenuation remedy. This will save the client $75,000 per year indefinitely.
