Monitor wells are sealed, concrete encased well pipes that extend into the ground to the groundwater level. These wells are found at most fueling stations, bulk fuel depots, convenience stores, airports, power production locations, industrial sites, landfills and waste dump sites, industrial sites and heavy manufacturing facilities. The monitor wells are designed to allow access to groundwater gradients. The function of these wells is to allow sampling of the groundwater in order to determine the amount of hydrocarbon in the water, which is also known as the aquifer. Plutus provides MWA© Monitor Well Additive for treatment of monitor wells. Contamination is reduced, as are remediation costs, reduced assessments or fines, and a cleaner environment is the end result.
