Groundwater: Monitoring

Volume 470: debated on Thursday 10 January 2008

To ask the Secretary of State for Environment, Food and Rural Affairs what the procedure is for monitoring groundwater levels; how frequently such monitoring is carried out; and what plans he has to increase the frequency. (175666)

The Environment Agency monitors groundwater levels from over 6,400 boreholes across England and Wales. These boreholes are monitored at frequencies ranging from every 15 minutes by automation to manually, either quarterly or half yearly.

The frequency of monitoring at any particular borehole is determined by the way in which the data is used and the hydro-geological setting from which it is being collected.
