Exhibit G CMLRB 112 Permit Application
Agile Slone Systems, Inc.
• 6.0 Water Quality Testing
Water samples from 10 locations on and neaz the project site were taken by San Luis
Valley Analytical, Inc., an independent lab. Locations included:
1) The spring at the Speer's residence east of County Road 157
2) Tallahassee Creek surface flow west of the Currant Creek confluence,
3) the Arkansas River water west of County Road 157,
4) a well in the NW comer of the permit area,
5) a well located next to the "depot building" north of the Speers residence
and east of the main entrance to the property,
6) a composite of spring flows exiting the gravel bank along the north side of
the Arkansas River in the southeastern edge of the permit area,
7) monitoring well #2 located between the gravel plant area and the southern
boundary of the affected land,
8) the Wootton residence well located 1,500'east of the permit area,
9) the Clazk residence well located >2,500' east of the permit area and
10) a sample from a spring flowing into the Tallahassee Creek at the extreme
eastern end of the permit azea.
Water samples were taken to answer particular neighboring land owner concerns and
team about the sub-surface hydrology and water flows. Neighboring land owner
concerns involved possible metals and/or toxic materials from past mining thought
evidenced from a light colored yellow clay exposure in the extreme western part of the
ranch. While no past evidence was found concerning past mining on the ranch or in any
records, water samples were still taken.
Based on a multiple linear regression of the chemical test results, some interesting
correlation coefficients were noted. The highest correlation coefficients occurre~
between water from the Tallahassee Creek, gravel spring flows, the Wootton well and the
Clark well.
3-4 water types aze demonstrated from the Piper Diagram analysis and supported from
the multiple regression statistical review.
1) Arkansas River Water (Ca HCO3, furthest to upper left in central diamond.
2) Bedrock (Clazk, Wootton, Northwest and Depot wells: Ca-
Na SO4-HCO3 furthest to upper right in diamond)
3) Currant Creek (Glacial deposit aquifer Ca-Na HCO3)
4) Dakota ?? (Spring at river Ca-Na HCO3)
The Speer's spring is more statistically correlated with the Tallahassee Creek water than
the Arkansas River water. This is probably due to the long term, yeaz round, ditch and
flood irrigation of the alfalfa field just north of the Speer's spring: The ditch and flood
irrigation water comes from water diverted from most of the Tallahassee Creek's flow.
The water flows through ditches into the SW comer of the permit area and then floods the
• alfalfa field within ~0' of the Steer's well, up gradient within gravel from the
