Abstract
Methods and systems are disclosed to assess clogging associated with a first well. The first well has a well screen or an open borehole in bedrock. A water sample is received from the first well during an ON state. Water is pumped from the first well during the ON state. A first oxidation reduction potential measurement and a first pH measurement are made on the water sample. First clogging specific information is determined for a first mineral or metal utilizing the first oxidation reduction potential measurement, the first pH measurement, and an Eh vs pH phase diagram for the first mineral or metal.

A system to determine precipitation of a first mineral or metal out of solution in a first water well, comprising:
- a well water analysis device, the well water analysis device further comprising:
- an aquifer chemistry module, the aquifer chemistry module to produce a measurement of oxidation reduction potential of a water sample from the first water well, wherein the water sample is taken from the first water well while water is produced from the first water well, the first water well having a well screen installed therein;
- and a measurement of pH of water taken from the first water well;
- an Eh-pH phase diagram for the first mineral or metal;
- a data processing system configured to accept the measurement of oxidation reduction potential and the measurement of pH;
- and
- a non-transient computer readable medium containing executable computer program instructions which, when executed by the data processing system, cause the data processing system to perform steps comprising:
- comparing the measurement of oxidation reduction potential and the measurement of pH with one or both of:
- (a) a precipitation zone on the Eh-pH phase diagram for the first mineral or metal;
- and
- (b) a border of a precipitation zone on the Eh-pH phase diagram;
- and
- determining the first mineral or metal is precipitating out of solution, the determining is based on the comparing, in response to the determining the system is configured to be reconfigured with the addition of a custom extended pump sleeve, the custom extended pump sleeve having a first end and a second end, the first end is attached to a well pump above a water inlet for the well pump, the second end extends down below a motor configured with the well pump.
