Arizona Well Owner’s Guide to Water Supply

Course Description GROUNDWATER PRODUCTION CEU TRAINING COURSE This short CEU training course is a detailed explanation of Water Distribution and Water Treatment Methods and related water fundamentals along with detailed understanding pumps and motors. This is an excellent course that applies to both Water Treatment and Distribution Operators. This course also covers in detail: Disinfection, Chlorine, O3 and disinfection alternatives, and related byproduct fundamentals. Water Quality, Tastes and Odor Problems and MCL/EPA Rules and a basic understanding of how the rules were created and implemented will be covered. This course will also cover advanced groundwater production and protection with distribution problem solving solutions.

•Assessment of the entire non-renewable ground water reserves •Distribution of the ground water reserves, their quality •Assessment of reservoir properties for all aquifers •Economic classification ↓ •MEWA Study of all aquifers on the Arabian Platform •MEWA Study of Western Coastal Plain and Harrats + Wadis

Abstract: Drinking water supplies are based on ground water resources all over the world. At some localities problems with higher concentrations of iron and manganese found in ground water. These higher concentration of these metals result in metallic taste of water, effect color and flavor of food and cause staining of different products like paper, cloths, and plastics. Therefore World Health Organization has approved the treatment of water if concentrations of iron and manganese are higher than 0.3mg/L and 0.1 mg/L. Several techniques have been applied to remove iron and manganese from groundwater. The issue of higher concentrations of iron and manganese in groundwater wells at Grindalsmoen in Elverum Municipality in the south eastern part of Norway has been investigated by a PHREEQC geochemical model. The aim of this investigation was to analyze the relationships between oxygen levels and precipitation rates of iron and manganese. For this purpose geochemical simulations were performed with PHREEQC model with radial and linear flow. Results proved that concentration of oxygen at the water works (at its corresponding partial pressure) is high enough to precipitate the level of iron and manganese found in groundwater. The concentration of oxygen in equilibrium air at our desired temperature of 6 degree centigrade was 12.3 mg/l calculated by PHREEQC. Geochemical simulations were performed by the one dimensional column flow and radial flow towards well. The phenomenon of sorption was also included in model to see the adsorption behavior of iron and manganese. Overall this geochemical study has provided satisfactory results.
