Abstract
A method and system for determining dynamic steady-state flow and chemistry of groundwater within a long-screened test well, includes (i) drilling a pilot hole through an aquifer; (ii) installing a test well within the pilot hole, including a well screen that is at least 40 feet in length; (iii) positioning a pump within the test well to move the groundwater within the test well; (iv) positioning a packer assembly within the test well to selectively provide a seal between the test well and the pilot hole; and (v) performing downhole testing at a plurality of different depths within the test well with miniaturized technologies that are equal to or less than 1.5 inches in diameter to determine a dynamic steady-state flow and chemistry profile of the groundwater within the test well. The pump is used at a first depth and then is moved to a second depth within the test well to perform stacked dynamic steady-state flow and chemistry profiles. The miniaturized technologies include a tracer injection system that determines downhole velocity and flow measurements of the groundwater within the test well, and a groundwater sampling system that selectively removes groundwater samples from the test well.
