This tabular dataset is the result of an analysis supporting the indicator 'Long-term Trends in Groundwater Levels in B.C.' published by Environmental Reporting BC in 2019. The analysis used groundwater level monitoring data from the Provincial Groundwater Observation Well Network as well as attribute data for all groundwater wells. The dataset 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). The R code for reproducing this indicator summary data is available on GitHub.
