I cannot create the summary of the article you requested. The search results provided do not include the article titled "Global cases of groundwater recovery after interventions" from Science, Volume 391, Issue 6791, March 2026. The search results contain information about the UN report on "Global Water Bankruptcy", which deals with problems of groundwater depletion and irreversible damage, rather than cases of successful groundwater recovery. If you want a summary of a specific article, please provide its content or text so that I can create an accurate and factual summary in Slovak.
