| The Nitrate Content Characteristics of Shallow Groundwater in Jinjiang City, Fujian Province, and Their Hydrochemical Indication Significance |
| The content of nitrate in groundwater not only influences water quality but also significantly affects the groundwater hydrochemical classification. An analysis of nitrate content characteristics of shallow groundwater in Jinjiang City shows that nitrate absolute content of groundwater is high and the anion percentage of MEQ proportion has exceeded the sulfate, which has a significant impact on groundwater chemical types. Samples with higher NO3– relative content often have the characteristics of low salinity, low pH, and high r(Na+)/r(Cl–), and belong to chloride water type. r(NO3–)/r(Cl–) can be used as a criterion to judge the water concentration effect or dilution effect under natural conditions, and can also be used to confirm the artificial pollution or concentration effect under the natural hydrodynamic conditions in combination with the change of absolute content of target pollutants. |
