Correlation analysis of various indicators in groundwater. Note: NO3-N: nitrate; NO2-N: nitrite; Cl−: chloride; F−: fluoride; SO42−: sulfate; NH3-N: ammonia nitrogen; CODMn: potassium permanganate index; TH: total hardness; TDS: total dissolved solids; depth: sampling depth of groundwater. * means that the 0.01 < P < 0.05 level is correlated, ** means P < 0.01 level is significantly correlated.
