“…A few studies specifically concerning the usefulness of Dockum groundwater have looked at its use for hydraulic fracturing, irrigation, and municipal drinking water supply. A study on the western side of the aquifer [37] looked at water quality potential for desalination as the Dockum in New Mexico was one of three more promising brackish aquifers there. Researchers examined the scale-forming factor (SFF) according to differences in water quality seen in New Mexico using the USGS PHREEQC model.…”

Within the US Southern High Plains, it is known that the Ogallala Aquifer (OA) has been over pumped since large-scale agriculture began making use of the water in the 1950s. One option to address the decline is to find new water sources. The last 10–15 years have seen an increase in drilling large capacity, deeper wells in the co-located Dockum Aquifer in the Texas Panhandle. This lower aquifer is separated from the OA by low hydraulic conductivity sediment and is thus generally considered independent from the OA. We examined the suitability of the Dockum to supplement OA water by comparing recent water chemistries where the aquifers coexist. We also examined historical information on well yield, well development, and water quality. We found that water quality is equivalent to the Ogallala in some places but in others it is saltier, softer, and more sodic. Use of PCA and hydrochemical facies revealed that even in this small area Dockum water quality is highly variable. We used USGS-PHREEQC to model water blending at ratios of 0–>100% Ogallala. We show that there is irrigation water quality risk no matter the blend, that risks differ according to location, and that the most frequent risks are salinity, sodicity, and nitrate. We conclude that growers can manage these risks if they use blending to choose the risks they feel most apt to mitigate.

There are direct links between water and energy use, sometimes referred to as the energy-water nexus. Water rights issues have confronted the southwestern U.S. for a long time. Furthermore, climate change is decreasing the already limited water resources in this region, and the growing population in the Southwest has also increased the consumption of freshwater. Here we study solar energy, which is abundant in the Southwest, as both an electric power source and the energy source to operate a desalination plant. We compare the use of different desalination technologies for seawater and brackish groundwater, which have different salinities. The data show that the dual-purpose reverse osmosis desalination plant is the most economical choice. However, since a multiple-effect desalination (MED) and a multistage-flash (MSF) can use waste heat for water production, desalinated water becomes a byproduct of the electric power plant, thus dual-purpose MED and MSF plants will be more economical than a single-purpose power plant. A MED plant using seawater or brackish water produces fresh water for $1.73/m 3 , while the costs are $2.811m 3 and $2.65/m 3 for a MSF plant using seawater and brackish water, respectively.

“…Scaling phenomenon constitutes a major problem in industrial and domestic installations. Indeed, scaling is usually observed in heat exchangers [1], boilers, cooling towers [2], desalination and water softening systems [3][4][5][6]. The CaCO3 deposits may cause serious technical damages such as the obstruction of the drains, a loss of effectiveness of the heat exchangers, and a seizing of the stopping devices (taps, valves…).…”

Scaling process is the main problem encountered in industrial plants using water. Several factors, (pH, temperature, hydrodynamic conditions, metal surface, and especially, water composition), can affect the scaling kinetics of calcium carbonate (CaCO3), one of the main component of scaling. In addition, some foreign ions added can considerably modified the scaling rates. In this work, the inhibiting effects of Zn 2+ and Cu 2+ cations on CaCO3 precipitation were studied in a 50°F synthetic carbonic solution by using fast controlled precipitation (FCP) and scaling quartz crystal microbalance (SQCM) methods, for homogeneous and heterogeneous scaling deposition, respectively. Results showed that Zn 2+ and Cu 2+ ions are efficient, at high concentrations (≥ 1 mg/L), to delay or even to prevent nucleation/growth of CaCO3. FCP measurements showed a complete inhibition of the homogeneous CaCO3 precipitation after 120 min in synthetic solution containing 5 mg/L and 4 mg/L of Cu 2+ and Zn 2+ , respectively. SQCM measurements showed that the surface coverage of the metallic substrate by a layer of CaCO3 is reduced when the amount of these cations increased. Zn 2+ cations inhibited the heterogeneous CaCO3 precipitation more efficiently than Cu 2+ . SEM and XRD results indicated that both cations affect calcium carbonate nucleation by changing the morphology of CaCO3 crystals.
