Water level data are collected over various lengths of time, dependent on their intended use(s). Short-term water level data are collected over periods of days, weeks or months during many types of ground water investigations (see chart below). For example, tests done to determine the hydraulic properties of wells or aquifers typically involve the collection of short-term data. Water level measurements needed to map the altitude of the water table or potentiometric surface of an aquifer generally are collected within the shortest possible period of time so that hydraulic heads in the aquifer are measured under the same hydrologic conditions. Usually, water level data ...
