Additional Information Category E: Surface Water for Irrigation

Purpose: This category is for surface water that is used for irrigating crops, fields, or other agricultural lands.

• Quality Requirements: The water needs to meet certain standards to ensure that it doesn’t harm plants, soil, or the overall agricultural system. For example:

  • The water should not contain excessive salts, heavy metals, or toxic substances that could harm plant growth or soil fertility.

  • It should have appropriate levels of nutrients, which can sometimes benefit crops, but also should not have excess nutrients that could lead to unwanted growth (e.g., algae) or pollution.

• Water Sources: The sources of water under this category include rivers, lakes, canals, or other surface water bodies that are typically used to irrigate agricultural lands.

• Suitability: The classification ensures that the water meets the basic criteria for safe and effective irrigation, reducing the risk of crop damage, soil degradation, or other negative impacts from poor-quality water.
