Abstract
A method for reducing the extent of treatment required for groundwater includes the step of determining one of groundwater flow and groundwater chemistry within at least one of a plurality of fluid zones within a subsurface well having a primary pump positioned at least partially therein. The method also includes modifying fluid dynamics within the subsurface well based on at least one of the groundwater flow and chemistry. The method further includes selectively extracting groundwater from at least one of the plurality of fluid zones with the primary pump. The method also includes removing one or more contaminants from the groundwater with a fluid treatment system. Additionally, the step of determining can include the use of miniaturized technologies, such as miniaturized flow profiling technologies, miniaturized water sampling technologies and miniaturized sensors.
