The three tabular datasets are the results of an analysis supporting the indicator 'Long-term Trends in Groundwater Levels in B.C.' updated by Environmental Reporting BC in 2024. The analysis used groundwater level monitoring data from the Provincial Groundwater Observation Well Network as well as attribute data for all groundwater wells. The datasets include: 1). Annual results of trend analysis by well: includes attributes (e.g. well name, number, lat/long, depth, aquifer type, region etc) for each well used in the analysis, as well as the results of the analysis (trend and significance) for the all-data, 10-year, and 20-year trend data. 2). Complete trending results of every option provided in the interactive data visualization, including monthly trends. 3). The monthly median groundwater levels (in m below ground) for each month of each year for each well used in the analyses. The dataset includes The R code for reproducing this indicator summary data is available on GitHub.
