12 miles

3. Taylorsville-Bennion Municipal Water District

5. Project Goals To compile well data for the TBID wells
To examine the degradation of water in these wells
Where is the poor quality water coming from?
Determine the window of time in which these wells can still be used
Look for correlations between
Water quality and depth of the well
Water quality and pumping

6. Total Dissolved Solids
A measure of water quality
The sum of the concentrations of major ions including sulfate, phosphate, chloride, etc.
The MCL for TDS is 2,000 mg/L

8. GIS Representation of Groundwater Degradation

9. 1988
LEGEND
High = 1500 mg/L
Low = 100 mg/L

10. 1995
LEGEND
High = 1500 mg/L
Low = 100 mg/L

11. 2003
LEGEND
High = 1500 mg/L
Low = 100 mg/L

12. Possible Solutions Water treatment
Purchase water from other outside sources such as Jordan Valley Water Conservancy District
Develop piping and blending systems that will mix increasing ratios of high quality water with the well water over time

13. The data used in this project was obtained
from the following sources:
USGS
State of Utah Engineer’s Office
Taylorsville-Bennion Improvement District
