Groundwater serves many purposes. It is a source of public and private drinking water, it is utilized as an industrial feedstock and it is used in agriculture for irrigation and cattle watering. The abstraction of groundwater also serves many civil engineering purposes such as structures, construction pit dewatering and remediation of polluted groundwater. Furthermore, groundwater is increasingly used for supply and storage of energy for the cooling and heating of buildings. Many wells abstracting groundwater suffer from impaired performance as a result of clogging by mechanical or biogeochemical processes. This represents a significant economic loss due to volume reductions, cost of well rehabilitations or construction of new wells. Cause and Prevention of Clogging of Wells Abstracting Groundwater from Unconsolidated Aquifers provides a comprehensive description of the various causes and processes associated with well clogging in addition to describing methodologies for diagnosis and prevention.

The book presents a comprehensive, yet concise analysis of groundwater occurrence, its development, technology involved in exploration, extraction, and its economical usage.The book makes use of minimum technical jargon, while explaining the basics of drilling, types of wells, their maintenance, development and testing, and selection of pumps. It discusses the causes for wells failing, methods of diagnosis and the pre-emptive and remedial measures, water transmission, composition, and purification. Unlike other natural resources, groundwater is replenished by rainfall. Nevertheless those who depend on groundwater either for industrial or agricultural sustenance should be responsive to certain factors that are significant to the long-term well-being of the water source. Important are: Whether the wells are being over-pumped, or under-pumped; the quantity and cost of water being drawn, whether there is sufficient water underground with optimum replenishment, and systems installed are compatible to the particular hydrological situation and similar such factors. The book attempts, in simplistic language, to link the gap between theory and practice; between the principles of groundwater as a natural science and its application technology. There are a number of pre-calculated tables that serve as a handy reference for Consultants, Drillers and Engineers who deal with groundwater on a day-to-day basis.

Groundwater constitutes an important component of many water resource systems, supplying water for domestic use, for industry, and for agriculture. Management of a groundwater system, an aquifer, or a system of aquifers, means making such decisions as to the total quantity of water to be withdrawn annually, the location of wells for pumping and for artificial recharge and their rates, and control conditions at aquifer boundaries. Not less important are decisions related to groundwater qUality. In fact, the quantity and quality problems cannot be separated. In many parts of the world, with the increased withdrawal of ground water, often beyond permissible limits, the quality of groundwater has been continuously deteriorating, causing much concern to both suppliers and users. In recent years, in addition to general groundwater quality aspects, public attention has been focused on groundwater contamination by hazardous industrial wastes, by leachate from landfills, by oil spills, and by agricultural activities such as the use of fertilizers, pesticides, and herbicides, and by radioactive waste in repositories located in deep geological formations, to mention some of the most acute contamination sources. In all these cases, management means making decisions to achieve goals without violating specified constraints. In order to enable the planner, or the decision maker, to compare alternative modes of action and to ensure that the constraints are not violated, a tool is needed that will provide information about the response of the system (the aquifer) to various alternatives.
