    • Uinta BasinBaseline Water-Quality Study Janae Wallace January 2011 update
    • OBJECTIVESCreate database of springs, creeks, wellsCreate database of water qualityCreate GIS data- chemistry mapsCreate baseline water quality (spatially andtemporally)- 2009, 2010, 2011Document changes in water quality
    • Map producedpre-studyshowingpotential wellandsprings tosample-fieldinvestigationshows mostof the sitesare unavailableto sample
    • Sample sites for data collected during spring of 2009
    • 2010 Events15 sites- 2 springs, 2 creeks, 11 wells Resample October 2009 Added 1 well site plus Green & White Rivers Spring 2010- added 2 wells (USGS testholes), 1 spring (unable to sample 3 well sites) Autumn 2010- 2 unavailable sites from spring now functioningTotal current sampling sites: 20

    • Sample sites for data collected during spring of 2010
    • Sample sites for data collected during spring of 2010
    • South Camp water well located in southernmostpart of the study area near PR Spring and SweetWater Spring; well is likely solar powered
    • Sweet Water Spring located near South Camp
    • KingsWell
    • Use of nearby pond is unknown; source of water likely from diverted USGS Testhole #6 well due south; &/or adjacent Bitter CreekCompound near Bitter Creek used by seasonal workers
    • USGS Testhole#6 located nearBitter Creek anddue south of BitterCreek Coral
    • R Sprng-Bitter Creek Coral;several spigots existat this site along witha housing compound;source of waterunknown
    • Bitter Creek Coral
    • Bitter Creek Coral Compound (including satellite dishes; source of water is unknown)
    • USGS Testhole #1 in Asphalt Wash; runoff/piped water feeds pond for wildlife
    • Another USGS testhole notavailable for sampling locatedsouthwest of Kings well
    • Another USGS testhole notavailable for sampling locatedin the southern part of WillowCreek drainage
    • Pack Mountain- Willow Creek- flowingDOGM well, water once allowed to flow to surface (left of slide) during 2009 sampling
    • Pack Mountain- WillowCreek- flowingDOGM well, water onceallowed to flow tosurface now is siphonedthrough a pipe for 2010sampling
    • Seep Ridge- samples originallyobtained from pond draining awayfrom pipe directly from well; pond used for wildlife
    • Seep Ridge- DOGMabandonned well wheresamples originallyobtained from pond drainingaway from pipe directly fromwell; samplesnow obtained nearpipe end shown in top photo
    • Windmill well - water in pond is generated bypower from the windmill; samplestaken in 2009 when windmill was in operation
    • Windmill well- During spring2010, the windmill was broken,no sample was taken; laterrepaired during sampling seasonautumn 2010 so a sample wastaken then
