Abstract
An in-situ monitoring tool is provided that is compromised of a non-reactive medium, a reactive medium, or a combination thereof, contained in a water-permeable mesh. The tool is placed in an aquifer for a predetermined amount of time to allow the medium(s) to act as a substrate that collects minerals from the aquifer for analysis.
Claims7
A device configured to be placed in an aquifer to passively collect particulate matter precipitated from groundwater therefrom, comprising:
- a cylindrical housing having an internal volume defined by a wall, the wall including at least one opening to allow fluid ingress and egress into the internal volume;
- a mineral trap comprised of a fluid-permeable member in the form of a sheet having a plurality of pockets separated by webs positioned between adjacent pockets, the plurality of pockets containing at least one of a reactive or a non-reactive medium;
- wherein the plurality of pockets are positioned adjacent an inner surface of the wall so as to create a void at least partially bound by the mineral trap;
- and
- wherein the plurality of pockets comprise a first pocket and a second pocket, and wherein a medium in the first pocket is different than a medium in the second pocket.

A method of monitoring water quality, comprising:
- providing a mineral trap assembly, comprising:
- a cylindrical housing having an internal volume defined by a wall, the wall including at least one opening to allow fluid ingress and egress into the internal volume;
- a mineral trap comprised of a fluid-permeable member in the form of a sheet having a plurality of pockets separated by webs positioned between adjacent pockets, the plurality of pockets containing at least one of a reactive or a non-reactive medium;
- and
- wherein the plurality of pockets are positioned adjacent an inner surface of the wall so as to create a void at least partially bound by the mineral trap;
- inserting the mineral trap assembly into an aquifer;
- removing the mineral trap assembly from the aquifer after a predetermined time;
- removing the mineral trap from the housing;
- severing the fluid-permeable member;
- removing at least a portion of the medium from the fluid-permeable member;
- and
- analyzing the portion of the medium.
