Monitoring Project in Hohhot, Inner Mongolia

Regarding water quality monitoring in Gengjiaying Village, Hohhot City, Inner Mongolia, water quality monitoring in rural areas is primarily aimed at ensuring the safety of drinking water for residents and the quality of water used for agricultural irrigation.

Drinking Water Source Monitoring: This includes natural water sources such as well water and spring water. Testing parameters may cover microbiological indicators (e.g., total coliforms), physicochemical indicators (e.g., pH value, hardness, dissolved oxygen), heavy metal content (e.g., lead, mercury, cadmium), and other potentially harmful substances (e.g., pesticide residues).

Surface Water Monitoring: For surface water bodies such as rivers and lakes, the main focus is on whether pollutant concentrations exceed permissible limits. Common monitoring indicators include ammonia nitrogen, total phosphorus, chemical oxygen demand (COD), and five-day biochemical oxygen demand (BOD₅).

Agricultural Irrigation Water Monitoring: The emphasis is on parameters such as salinity, heavy metals, and other components that may be harmful to crop growth.
