MONITORING WELL LOCATION

Compass Consulting Surveyors have extensive experience providing monitoring well locations for various purposes, including mining, contamination investigation and monitoring.

Compass Consulting Surveyors have been involved with many monitoring well location projects for contamination investigation in Central West NSW. In addition, wells have been located for mining projects. The services of a surveyor are required to determine the location and level of monitoring wells.

The results of a monitoring well location survey are presented as a plan showing the location of the wells in relation to the subject site and a table with the MGA2020 coordinates of the well, the level of the lid of the well and the level of the well head. In most cases, the plan will show an aerial image of the site as background information.

Monitoring wells for contamination investigation are installed at facilities with above-ground or underground fuel tanks, such as fuel depots, service stations and private land. The wells are used to check the quality and level of groundwater across a site. The wells are monitored periodically, with a monitoring interval dependent on the type of monitoring being carried out and the severity of the contamination involved. In cases where groundwater is severely contaminated, rehabilitation wells or injection walls can be installed, so chemicals can be introduced to the groundwater to break up any contamination present.

Contaminated sites may have a varying number of wells installed, with our largest well location project to date having some 80 wells for groundwater monitoring, testing and rehabilitation, extending over an area of approximately 32 hectares and over a period of seven years. Often, monitoring wells are installed at the completion of new built service stations and monitored periodically to ensure that any fuel leakage into the groundwater is detected early. In such cases, monitoring wells have more of a preventative role than a remediation role.

Compass Consulting Surveyors can provide coordinates and levels for monitoring wells for all purposes to a specified accuracy and present the data in a format that is clear and easy to understand.
