groundwater remediation
Josh Grasser, the Regenesis Remediation Services project supervisor, keeps a close eye on his monitoring equipment located on Central Avenue. He is overseeing a contaminated fuel plume remediation project which will neutralize the contaminants in the soil left by a fuel leak.
Superior residents may have noticed a hive of mechanical activity on Central Avenue south of Third Street. The array of equipment is part of a groundwater remediation project.
Harold's Auto Service is located at the southwest corner of Third and Central. Before Harold Kramp established his business, the site was a Conoco service station for many years. Before that, it was one of the earliest gasoline stations in Superior. At some time the underground fuel tanks deteriorated. The leaked fuel into the ground. Monitoring wells were installed to track the progress of the fuel leakage.
Regenesis Remediation Services has undertaken the remediation of this fuel plume.
The project is expected to take two more weeks to complete. When complete, the plume will eventually be neutralized and the threat to groundwater eliminated.
Regenesis is a global company specializing in environmental remediation.
The process being utilized in Superior involves the injection of colloidal activated carbon into the fuel plume. The advantages of this method are lower costs. The barrier absorbs the fuel, effectively neutralizing the elements contributing to the contamination.
The Plume Stop carbon method will eliminate the contaminants.
The project technology, a proprietary process, does not require the installation of any further equipment. Similar projects have completely eliminated the fuel plume or contained to where the fuel is no longer a threat to the environment.
The process involves injecting the carbon, which is diluted with water, directly into the fuel plume. Grasser estimates the carbon will have eliminated the majority of the contaminants within a six-month period if not less.
The process is controlled by computers which advise the operator as to the amount of carbon required.
This is one of several projects in Superior which have been undertaken to remove contaminants from the ground because of leaky fuel tanks. Many have been completed.
There are several monitoring wells in Superior.
The cost of the project is funded by the State of Nebraska.
