Rymes Project Highlights
Contaminant: Petroleum hydrocarbons
Location: Rymes Propane and Oil Inc, Concord, New Hampshire
Industry: Commercial heating, oil and gas
Problem Situation: BTEX (benzene, toluene, ethylbenzene and xylenes) contamination
BioStryke™ Solution: BioStryke™ TPHENHANCED™
Results: Greater than 50% reduction in total BTEX
Ultimate Results: Based on the pilot, a full-scale remediation program has been proposed for the site and is presently under NHDES review.
Innovative Green Remediation In-Situ
In the Rymes remedial pilot study of an innovative technology, TPHENHANCED™ was able to demonstrate green remediation and low carbon footprint by transforming petroleum constituents in-situ to harmless byproducts without excavation and disposal, or the long-term use of power-consuming, carbon dioxide-emitting engines.
The Pilot Study results demonstrate the following:
The proprietary, patent-pending amendment BioStryke™ TPHENHANCED™ was successful in expediting hydrocarbon metabolism at Pilot Study wells located within the area of influence (AOI) of the PRS deployment (i.e., well ISOC-2), as well as, downgradient performance wells GZ-1 and GZ-2;
Greater than 50% Reduction in BTEX concentrations were generally achieved for the three well locations within the AOI of PRS deployment; 100% Reduction, 65% Reduction, and 88% Reduction in total BTEX concentrations for all three Pilot Study wells: ISOC-2, GZ-1, and GZ-2, respectively;
BTEX concentrations remained significantly less than the initial concentrations (minimal rebound) 10 months after the conclusion of the pilot test, indicating the destruction of mass caused by the BioStryke™ TPHENHANCED™ process.
BioStryke™ TPHENHANCED™ is a sustainable and green (low carbon footprint) remedial option for petroleum-impacted sites, with the end products generally being water, carbon dioxide, innocuous gas, and microbial biomass;
BioStryke™ TPHENHANCED™ resulted in an overall increase in pH of about 0.5 to 1 standard units at the PRS deployment well and performance well GZ-1. Given that petroleum typically effects a lower pH condition on groundwater, due to carbon dioxide production during mineralization, the increased pH likely further enhanced microbial metabolism; and based on the fact that the performance goals were both met (>50% Reduction in total BTEX), it is Rymes’ opinion that the Pilot Study using BioStryke™ TPHENHANCED™ was a success, and a full-scale remediation program has been proposed for the site and is presently under NHDES review.
