AN INSIDE VIEW: GROUNDWATER MODEL Terminology: Piezometer – piezometers are usually installed by researchers studying groundwater in a particular area. Since groundwater flows from high areas to low areas, knowing the height of water in a number of piezometers can allow you to map the direction of flow. Drinking water well – drinking water wells are normally regulated by state codes which specify the depth required and the materials used in construction. They are carefully located away from sources of contamination. Concept 1. Height of water table Your TA will add dye to piezometers A, E (blue) and to B, C, D, F, G (green). How can you identify (recognize) the height of the water table?
