A well installed at a site to determine the direction of ground water flow, levels of contamination and other ground water characteristics.
A non-pumping well, generally of small diameter, that is used to measure the elevation of a water table or water quality. A piezometer, which is open only at the top and bottom of its casing, is one type of monitoring well.
a well drilled at a specific location on or off a hazardous waste site at which groundwater can be sampled at selected depths and studied to determine the direction of groundwater flow and the types and quantities
A well or drillhole constructed for the purpose of obtaining information on the physical, chemical, radiological, or biological characteristics of the groundwater.
A well used either to collect water samples for purposes of water quality testing, or to measure groundwater levels.
An installation featuring the setting of tubular perforated screen into a soil bore, to depths below groundwater level, so as to provide ready access to the same for sampling or depth monitoring purposes.
A hole drilled into the ground with a pipe inserted to allow for the collection of groundwater samples.
A well constructed or used for the purposes of water level or water quality data collection. Monitoring wells are often installed to provide an early warning of contamination occurring down gradient from a landfill or industrial facility.
A well drilled for the purpose of sampling groundwater to determine the characteristics of the water and the presence or absence of contaminants.
An arrangement of hollow piping constructed to provide ongoing surveillance and monitoring of groundwater and soil conditions.
(1) A well used to obtain water quality samples or measure groundwater levels. (2) A well drilled to collect groundwater samples for testing to determine the amounts, types, and distribution of contaminants in the groundwater beneath the site. The well enables samples of groundwater to be collected at a specific horizontal and vertical location for chemical analysis. Sometimes soil samples are also collected as the well is being drilled.
A non-pumping well used for drawing water quality samples.
A non-pumping well designed for measuring water levels and testing ground-water quality. Wells can be drilled to various depths to monitor water at different levels. The image on the right illustrates one possible design. Click on the image for a larger view.

a well placed in a media for the purpose of collecting samples, observing conditions, and collecting data
Non-pumping well used primarily for drawing water-quality samples; also for measuring ground water levels.
1. A well used to obtain water quality samples or measure groundwater levels. 2. A well drilled at a hazardous waste management facility or Superfund site to collect ground-water samples for the purpose of physical, chemical, or biological analysis to determine the amounts, types, and distribution of contaminants in the groundwater beneath the site.
