Title: Innovator John A. Cherry: Advancements in Fracture Flow Measurement and Groundwater Contamination Solutions

Introduction

John A. Cherry, based in Waterloo, California, is a notable inventor recognized for his contributions to the fields of environmental and civil engineering. With a robust portfolio of 9 patents, Cherry has made significant strides in developing innovative solutions for measuring fluid dynamics and addressing groundwater contamination issues.

Latest Patents

Among Cherry's latest inventions is a device and method for measuring fluid fluxes, solute fluxes, and fracture parameters in fracture flow systems. This improved method allows for simultaneous monitoring of fluid fluxes and contamination levels across various flow systems, including both screened and unscreened boreholes. The invention employs a specially designed sorbent layer that retains dissolved contaminants while being attached to an impermeable flexible liner. Additionally, the approach allows for the estimation of critical parameters such as fracture locations, separations, inclinations, and orientations within a fracture flow system. The monitoring process facilitates the sorption of contaminants over specific intervals, followed by their subsequent analysis to determine cumulative fluxes and flow directions.

Another significant patent addresses the issue of Dense Non-Aqueous Phase Liquid (DNAPL) contamination in groundwater. This invention involves the treatment of DNAPL lenses suspended on clay strata within sandy aquifers. By injecting a potassium permanganate solution into the aquifer, it forms a treatment disc that gradually permeates through clay, effectively targeting and alleviating contamination.
