Abstract
A method for reducing the extent of treatment required for groundwater comprises the steps of (A) determining one of groundwater (1) flow, and (2) chemistry within at least one of a plurality of fluid zones within a subsurface well having a primary pump positioned at least partially therein; (B) modifying fluid dynamics within the subsurface well based on at least one of the groundwater flow and chemistry; (C) selectively extracting groundwater from at least one of the plurality of fluid zones with the primary pump; and (D) 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.
