Standard Practice for Monitoring Well Protection At or Near Land Surface

Importancia y uso:

4.1 An adequately designed and installed surface protection system will mitigate the consequences of natural damage (e.g., freeze/thaw damage) in susceptible areas, or anthropogenic damages, which could otherwise occur and result in either changes to water level and/or groundwater quality data, or complete loss of the monitoring well.

4.2 The extent of application of this practice may depend upon the importance of the monitoring data, cost of monitoring well replacement, expected or design life of the monitoring well, the presence or absence of potential risks, and setting or location of the well.

4.3 Monitoring well surface protection should be a part of the well design process, and installation of the protective system should be completed at the time of monitoring well installation and development.

4.4 Information determined at the time of installation of the protective system will form a baseline for future monitoring well inspection and maintenance. Additionally, elements of the protection system will satisfy some regulatory requirements such as for protection of near surface groundwater and well identification.
