Well Field Configuration
Approximately 40 wells
2,000 gallons/minute
350-500 feet deep
30-40 year life
Final well locations are under review

Projected Well Field Effects
Some water table drawdown outside of GGS property boundary field is expected
Pumped water will not be released to the downstream canal system other than through normal seepage/leakage
No influence on Republican River system
Low net consumption of water over time

Groundwater Monitoring- Overview -
Monitor effects of the GGS well field operation
To update groundwater model for use as a predictive tool for mitigation
![Page 14: 1 Gerald Gentleman Station Well Field Meeting April 26, 2004](https://reader033.vdocuments.mx/reader033/viewer/2022051620/56649f0e5503460f94c222e0/html5/thumbnails/14.jpg)

Groundwater Monitoring Process
Bi-annual Independent monitoring by Twin Platte NRD
Thirty (30) existing non-NPPD wells near Sutherland Reservoir
Continuous monitoring of GGS wells
Additional NPPD monitoring of some wells off NPPD property
Data collected will be available to the public

Well Mitigation Process
Board Resolution
NPPD will proactively identify and mitigate potential effects of the GGS well field on neighboring wells before these effects create adverse impact
Neighboring well owners can also contact NPPD to initiate the mitigation process
Challenge is identification of well problem causes
