Statement

Annual mean groundwater levels were calculated for the period 1990 to 2019, as the arithmetic mean of the interpolated monthly values for the calendar year, and a five-year running mean was calculated from the annual means of each monitoring station. Taking the five-year period 1990 to 1994 as a baseline, five-year running means were estimated as percentages with respect to the baseline. Values greater than 100% imply that average groundwater levels have risen since the period 1990 to 1994, while values less than 100% imply falling levels. The five-year running means were arithmetically averaged for each region that contained at least one monitoring station. The interpolated data, annual averages and five-year running means were then plotted as time series and subject to a heuristic QA process to identify any anomalies within the data.
