The Central Ground Water Authority (CGWA) involves various laboratory tests to assess the quality and safety of groundwater. These tests can be broadly categorized into physical and chemical parameters. Physical parameters include tests for pH, temperature, turbidity, total dissolved solids, and electrical conductivity. Chemical parameters involve tests for various ions, nutrients, and contaminants that can affect the environment.
These laboratory tests also include analysis of water samples for various environmental parameters, such as hardness, alkalinity, and acidity. Additionally, tests are conducted to detect the presence of various pollutants and contaminants, such as heavy metals, pesticides, and industrial chemicals. These tests provide valuable data to assess the quality of groundwater and identify potential environmental hazards.
