Standard Practice for Monitoring Well Protection At or Near Land Surface
|Publication Date:||1 January 2020|
|ICS Code (Equipment for drilling and mine excavation):||73.100.30|
This practice identifies design and construction considerations to be applied to monitoring wells for protection from events, which may impair the intended purpose of the well such as water level or water quality monitoring data.
The installation and development of a well is a costly and detailed activity with the goal of providing representative samples and data throughout the design life of the well. Damage to the well at the surface frequently results in the loss of the well or can potentially impact measured water level and/or groundwater quality data. This standard provides for access control so that tampering with the installation should be evident.
This practice may be applied to other surface or subsurface monitoring devices, such as piezometers, permeameters, temperature or moisture monitors, or seismic devices.
Units-The values stated in SI units are to be regarded as the standard. The inch/pound units given in parentheses are for information only. Reporting of test results in units other than SI shall not be regarded as non-conformance with the standard.
All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026, unless superseded by this standard.
