  • Qualitative analysis identifies which substances or ions are present in the water, such as heavy metals, nitrates, or bacteria.
  • Quantitative analysis determines how much of each substance is present.
  • Both are important because knowing what contaminants are in the water and in what concentrations allows assessment of whether the water meets safety standards and is suitable for consumption or environmental use.
