Dynamic Flow & Chemistry Profiling

Dynamic Flow Profiling



Increasingly stringent standards for trace levels of contaminants such as chromium, arsenic, nitrates, and TCP in combination with a surge in demand for groundwater resources have led to a need for more efficient and precise well characterization.

Under exclusive license to BESST Inc. from the U.S. Geological Survey, the DyeTracer system facilitates injection of rhodamine dye solution at varying depths in a well while the well is still operating at a steady state. The return rate of the injected dye provides exceptional data that is analyzed by BESST to determine flow dynamics throughout the well. Other conventional methods of characterizing wells are expensive, involve disrupting water service and do not accurately represent water quality with flow velocity data during steady state pumping conditions. BESST’s miniaturized technology allows the well to operate normally while the diagnostic analysis is conducted, which provides representative data under actual pumping conditions.


  • To determine pathways of water migration into a well.
  • To determine mass transfer of contaminants throughout the well.
  • To delineate flow contribution zone by zone along the screened section of the well.
  • To delineate zonal percentage contribution along the screened section of the well.
  • To develop a customized sampling plan for water quality analysis.
  • To reduce or eliminate dependence on expensive treatment technologies.
  • To delineate plume migration within an active well field.

Combining BESST’s HydroBooster Pump System with the Dynamic Flow Profile has produced diagnostic data that has revealed opportunities for a magnitude of different well modifications. Installation of sleeves and packers at precise depths along well screens has reduced the amount of contaminants entering wells. In turn, this has diminished water treatment cost savings that has been estimated to nearly 80 percent annually. Engineered suctions and pump replacements are a common modification that is a result of the Dynamic Flow Profile.
