between groundwater and rivers or wetlands has led to a greater emphasis by the MDC on a whole catchment approach to understanding freshwater quality. When starting a preliminary groundwater investiga-tion, all geologic, groundwater, and well drilling data pertinent to the area should be reviewed including available well records. 3.

Introduction 3. Background 2. Rock: includes all the different types of ancient hard rock (sometimes called ‘bedrock’) found throughout Nature and Movement of Groundwater The groundwater movement takes place through pore spaces at extremely slow velocity. The manual ‘Understanding Groundwater & Wells in manual drilling’ complements the 4 technical training handbooks and highlights those essential subjects which are relevant to manual drilling, geo-hydrology, hygiene, well installation and well development in practice, in simple and 4. type will have fractures that can be problematic unless treated in design. 2. Groundwater is found in the soils and rocks below the entire surface of Ireland. T One person’s actions can have an effect on groundwater. Ground water is water that fills pores and fractures in the ground, much as milk F Groundwater can’t get polluted. The flow velocity of groundwater is expressed in metres-1 day. Groundwater is an invisible natural resource. This determines the type of data that have to be collected and the location and distribution of the monitoring network boreholes. Ground-Water Quality 43 GROUND-WATER QUALITY The geochemistry of ground water may influence the utili-ty of aquifer systems as sources of water. Maps A study of available resource maps is an excellent way 1. people envision that ground water exists somehow in a mysterious, hidden system of underground rivers, reservoirs, and water “veins.” Although these terms may be use-ful when speaking metaphorically about ground water, they are far from accurate. The planners of agricultural waste management practices should be familiar with T Groundwater is part of the water cycle. Table 5.1 Types of data required for groundwater management TYPE OF DATA STATIC DATA No significant variation with time F Groundwater comes from lakes and rivers underground. An overview of groundwater-related wetlands 3.1 Types of groundwater and groundwater-related wetlands Factors influencing groundwater chemistry The chemical composition of groundwater is determined by a number of influences. Table 5.1 below summarizes static and dynamic data types. 6. The types and con-centrations of dissolved constituents in the water of an aquifer system determine whether the resource, without prior treat- more aspects of the groundwater resource. 3 Groundwater geochemistry In this section we will look at the general chemical characteristics of groundwaters, and at some of the geochemical processes that are important in the chemical evolution of water that flows through the ground – including carbonate equilibrium, oxidation-reduction reactions and adsorption-desorption processes. These include the mineralogy of the rock types forming catchments T Groundwater is found beneath the earth’s surface. It is available in different proportions, in various rock types and at various depths, on the surface layer of the earth. 7. T Groundwater is stored in between the rocks and soil underground.
