As part of the local limestone’s quarry’s planning conditions preceeding the extension and landfill, they will have to carry out water monitoring of the adjoining SSSI and groundwater to generate a record of the water levels and the quality as an indicator of whether their activities are having an effect on the local environment.
Preceding the installation of water level recorders, we have installed mounting points within the SSSI and feed ditch from the River Cam.
The pools were originally created by lime extraction by hand and the base of the pool follows the strata of hard lime. This was more difficult to break through with picks, resulting in a pool with an almost flat solid bottom. These are very rare features in water courses.
The primary pool is actually much deeper than it appears with the visible vegetation floating over a pool between 1.5 and 2 metres deep. This environment is extremely dangerous and buoyancy aids are essential when working in this area.
