A Glossary of Hydrogeology

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.

Purpose and Scope of this Document: The purpose of this guidance document is to present a recommended approach to designing and constructing monitoring wells for groundwater investigations at contaminated sites. The state-of-practice of environmental characterization has changed substantially since 1995, when the original guidance was released. The intent of this revised guidance is to update the original guidance regarding recent developments and to discuss groundwater monitoring wells within the context of recent developments. In that regard, the overview below provides a thumbnail sketch of the differences between this document and the original guidance.

Abstract: The purpose of the study to investigate the impact of the presence of iron and manganese found in  groundwater. The concentrations if both minerals as well as the location of the water source were identified along with its impact on water quality. Also, in this investigation a suitable method or  technique for the removal of both iron and manganese is selected taking into consideration the  local economic and environmental aspects. The removal will be accomplished by oxidizing both iron and manganese using aeration or using dissolved chemical oxidants converting them from  soluble to insoluble precipitates. Precipitates of iron and manganese hydroxides are formed and removed from water through settling and filtration units. In this research the concentrations of iron and manganese were analyzed from groundwater aquifers of a number of towns in the southern part of Libya. These concentrations were compared to the local and international drinking water standards set by the World Health Organization (WHO). Some water samples reported have shown a wide difference in iron and manganese concentration and selected for treatment in this  investigation. A complete treatment system has been designed to remove iron and manganese for  the groundwater at Brak city of Alafia since the iron and manganese exceeds the limits. The  oxidation of iron and manganese was done via aeration followed by flocculation and, settling,  filtration and finally disinfection. At Alafia city, iron and manganese concentrations were 3.1mg/L, and 0.32mg/L respectively as compared to the standards set by the World Health Organization,  2004 for concentrations of 0.3 mg /L, 0.1 mg /L respectively, This process is believed to be very  effective and economically feasible in the removal of both iron and manganese.
