In our Anglian region groundwater levels are still exceptionally low.

Changes in groundwater levels may also be measured and identified with gravitational methods.

In arid areas it may not fill due to deep groundwater levels.

In 2010, two energy companies confirmed their mines have the potential to affect groundwater levels.

In the late 1910s, a problem developed with rising local groundwater levels caused by irrigation.

These facilitated a rise in the groundwater levels and helped turn the area into a "white zone".

The groundwater level is always less than 5 feet below the soil surface.

Timber will last for a long time below the groundwater level.

Hence, timber tends to last for a long time below groundwater level.

The excavations were difficult because the human structures lay below groundwater level.
