Abstract groundwater level changes in the yata river basin (japan) were investigated first by comparing the results of simultaneous field observations in 1999.
The observation well network is equipped with electronic dataloggers and telemetric units that record water levels every hour and transmit the data to a central computer. The wells are visited approximately every six months for field verification and water samples are collected periodically to test groundwater chemistry.
Tests strips and color wheels, which cost less than the colorimeter, are useful for identifying nitrate-impacted ground water. Alkalinity field-measured alkalinity provides a more accurate estimate of bicarbonate concentrations in ground water than a laboratory measurement.

Because ground water is hidden from view, ancient man could only theorize as to its sources of replenishment and its behavior. His theories held sway until the latter part of the 17th century, which marked the first experimental work to determine the source and move ment of ground water.
Unlike a surface dam, a subsurface dam does not allow direct observation of water storage. It can only be estimated from the groundwater level observed using.

Ground water elevations are typically determined from observation wells or piezometric wells. In stream-side areas, the subsurface free water elevation is often monitored in studies of riparian plant communities, nutrient transport, and seasonal waterflow direction.

Groundwater pollution (also called groundwater contamination) occurs when pollutants are despite the epa's lack of profound widespread evidence, other researchers have made significant observations of rising groundwater contamina.
The importance of considering ground water and surface water as a single resource has become increasingly evident. Issues related to water supply, water quality, and degradation of aquatic environments are reported on frequently.

Ground water samples are collected from these observation wells once a year during the month of april/ may to obtain background information of ground water quality changes on regional scale. The database thus generated forms the basis for planning the ground water development and management programmes.

Groundwater is an important component in many industrial processes.
We have also briefly looked at the ground-plane vertical in free space, where the four ground-plane radials form a built-in “ground” system. Perfect ground makes a vertical monopole into the functional equivalent of a center-fed dipole, although the feed-point resistance at resonance is half that of the center-fed dipole.
