May 2014 overview
Chalk water levels generally fell during May but remained within the normal range or above, with exceptionally high levels at Stonor Park (Chilterns). However, in Yorkshire levels remained below average, even though the monthly rainfall total over the chalk of Yorkshire was mostly >175% of the average for May. Local rises in levels were recorded in parts of Lincolnshire and Suffolk.
In the Permo-Triassic sandstones, despite falls, water levels remained above previous monthly maxima in the north-west (for the fifth consecutive month) and were also very high in the south-west. Levels elsewhere were above average and rose in north Wales.
In the Upper Greensand of south-west England, at Lime Kiln Way, levels fell slightly
but remained above the previous monthly maximum for the fourth consecutive month.
In the Magnesian Limestone, water levels in the indicator boreholes were notably high in the north. In the other limestone aquifers, levels returned to the normal range, except at Pant y Lladron where they were exceptionally high with a rise of 5m recorded across the 24th-25th May in response to rainfall
