| The objective of this work is to characterize water samples from the southwestern area of the Navajo Reservation. Field samples were collected between summer 2003 and summer 2005. Major cations and anions were determined as well as uranium and arsenic content. We investigated fluctuations in water chemistry due to seasonal changes in the environment. Results from these analyses indicate no significant seasonal variations in values. Unexpectedly, results do indicate well-to-well variation in water chemistry primarily in major anion content. Similarly, unexpected well-to-well variations in uranium and arsenic levels were observed. In order to better understand this variation in the water chemistry, we have begun acquisition of new hydrogeologic data, in collaboration with U.S. Geological Survey in Flagstaff. Greater insight is needed into the environmental causes of the variation in water chemistry observed in wells in the southwestern corner of the Navajo Nation. |
