Abstract
Groundwater level decline is a problem experienced in aquifers with more than one groundwater user
such as the Grootfontein dolomite aquifer in the North West Province of South Africa. This study
assessed groundwater level fluctuation trends for monitoring boreholes within municipal and irrigation
groundwater abstraction areas. The study also determined the influence of rainfall and municipal
groundwater abstraction as the dominant factors responsible for groundwater level fluctuation in the
area. The study further recommended possible interventions for declining groundwater levels within
the Grootfontein dolomite aquifer study area. Analysis of groundwater level fluctuation trend was
conducted from 1980 to 2020 using Mann-Kendall and Sen's slope statistical tests. The results showed
that groundwater levels in the study area had a declining trend. Spearman rank correlation was used to
determine the influence of rainfall and municipal groundwater abstraction on groundwater level
fluctuation within the study area.
