Remediation of contaminated groundwater is becoming increasingly more
important as much of the U.S. population relies on groundwater for their drinking water.
Contaminates such as Chromium, common pollutant at industrial waste sites, and
Hexavalent chromium which is toxic to humans, animals, and plants are major
concerns. Chlorate, another contaminate of concern, has been widely detected in
ground and surface water in the United States and even locally in Henderson Nevada at
the Nevada Environmental Response Trust (NERT) sites. To assist in mitigating this
issue, this research focuses on the removal of high levels of hexavalent chromium (ppm
range) (Cr(VI)) and …

Groundwater depletion has been one of the major challenges in recent years. Analysis of groundwater levels can be beneficial for groundwater management. The National Aeronautics and Space Administration’s twin satellite, Gravity Recovery and Climate Experiment (GRACE), serves in monitoring terrestrial water storage. Increasing freshwater demand amidst recent drought (2000–2014) posed a significant groundwater level decline within the Colorado River Basin (CRB). In the current study, a non-parametric technique was utilized to analyze historical groundwater variability. Additionally, a stochastic Autoregressive Integrated Moving Average (ARIMA) model was developed and tested to forecast the GRACE-derived groundwater anomalies within the CRB. The ARIMA model …
