Heavy Metal In Water Resources, Zuming Bi, Jeanne Sumrall
SACAD: Scholarly Activities
Heavy metal pollution in surface water has posed a serious threat to human health. The goals of this research are to analyze the concentration and distribution of key heavy metals and compare the measured values with global standards. This study analyzed major heavy metals like Fe, Mn, Cu, Pb, and Ag across several test points in Kansas and converted them to standard units mg/L. Based on the statistical graph, heavy metal iron and manganese levels are exceeded USEPA and WHO limits several times, while other heavy metals stay in the safe range. The results indicate that the pollution in Kansas …
Examining The Useability Of The Dakota Aquifer In Kansas For Irrigation Regarding Salinity, Alexander D. Leiker, Jeanne Sumrall
Examining The Useability Of The Dakota Aquifer In Kansas For Irrigation Regarding Salinity, Alexander D. Leiker, Jeanne Sumrall
SACAD: Scholarly Activities
The Ogallala Aquifer has been overused for decades, so alternative water sources, such as the Dakota Aquifer, must be considered to prevent it further declining. However, the Dakota Aquifer is not a feasible alternative in many locations. To evaluate irrigation useability, existing well water data across the geographic region was analyzed. Salinity and Total Dissolved Solids (TDS) were considered with existing data on plant salinity tolerance, especially those crops common to Kansas farmers. Results showed that most areas in southern Kansas that had access to the Dakota Aquifer could use it for irrigation, though counties closer to the Kansas-Nebraska state …
