SUBJECT Comparing the Uranium Concentration Results Between USGS Seeps and Springs
Samples and DUSA Seeps and Spnngs Samples in the Vicinity of the White Mesa Mill
near Blanding Utah
The USGS did a report called Assessment of Potential Uranium Emissions from a Uranium Mill on Water
Sediments and Plants Located near the Ute Mountain Ute Reservation Utah (hereafter Report) In one
section of this Report the USGS summarized m a graph total uranium distnbution in water from wells and
springs that they sampled in the area surrounding the DUSA White Mesa Mill The springs that the USGS
sampled included Entrance Westwater Cottonwood and Ruin which are spnngs that DUSA samplings
To compare results DUSA uranium sample results are hand marked in red on a copy of the graph that the
USGS used to summanze their uranium results (see Attachment 1) In comparing results it should be noted
that the USGS analyzed for total uranium and DUSA has analyzed for dissolved uranium
It appears results are similar between Rum (DUSA 8 11 pg/1 and USGS 10 pg/1) and Cottonwood spnngs
(DUSA 4 - 8 pg/1 and USGS 10 pg/1) The DUSA results for the Westwater Spnng are 15 and 46 \igl\
where the USGS results are lower ranging between 2 to 11 pg/1 The DUSA results for the Entrance
Sprmg are 15 2 and 17 8 pg/1 where the USGS results are higher ranging between 25 to 55 |Lig/l (see DUSA
seeps and spnngs sample results m tables 1 5 m Attachment 2) The possible reasons for the different
sample results are 1) dissolved (DUSA) vs total (USGS) uranium analysis 2) sampling procedures and
3) different laboratones
