Which consequence results when limestone dissolution causes sinkhole formation?

💡 Explanation

Increased upstream groundwater contamination results because sinkhole formation causes direct conduits between surface pollutants and the aquifer through dissolution, therefore contamination increases, rather than filtering through sediment or clay layers like normal groundwater flow.
