“…This study is primarily based on the existing database of sampling results from three institutions responsible for monitoring groundwater quality in the study area. This database was originally created as part of the INCOME project (LIFE07) for the period 1992-2011 [90], updated and expanded as part of the AMIIGA project [8] for the period 2011-2016 and additionally updated in 2020 for the period 2016-2019, so that it now documents a total of 283,538 entries. The database contains information on 473 chemical and physico-chemical parameters and 164 monitoring sites in two hydrogeologically connected aquifers, Ljubljansko polje and Ljubljansko barje.…”

Urban areas can significantly alter the quality status of aquifers if appropriate strategies to prevent and detect groundwater contamination are not implemented in time. The prevention of groundwater contamination should be a priority due to its potential long-term impact on the environment and the high cost of remediation. For effective and sustainable groundwater management, it is crucial to proactively monitor a wide range of compounds to prevent their spread, progression and increasing concentrations. This study is one of the few to analyse the trends of various urban groundwater contaminants (nitrate, sulphate, hexavalent chromium, pesticides, PCE and TCE) from a groundwater management perspective. Characteristic trends are assessed using linear regression and the Mann–Kendall method, while significant changes in trends are determined using the Darken and Pettitt tests. The time span of the analysed trends covers the transition period before and after the implementation of the Water Framework Directive (2000/60/EC) and the Groundwater Directive (2000/60/EC). This study confirms the effectiveness of enforcement measures to protect groundwater quality, as evidenced by several statistically significant decreasing trends. On the other hand, this study emphasises the importance of intervention-targeted sampling campaigns and the reporting of raw analytical values according to the ISO 11843 series of standards. This approach is essential to detect upward trends in emerging contaminants at an early stage and prevent them from reaching levels that could negatively impact the economy or even jeopardise the safety of drinking water supplies.
