The water quality test is somewhat normal.

China's water management department stipulates that the TDS value of domestic tap water should be below 300PPM, purified water should be below 5PPM, and mineral water should be between 100-200PPM. Therefore, the TDS value range of water quality should be less than 300PPM to be qualified.

Standards for different types of water quality:

Class I water quality: good water quality. Groundwater only needs disinfection, and surface water can be drunk after simple purification and disinfection.

Class II water quality: the water quality is slightly polluted. After conventional purification treatment (such as flocculation, precipitation, filtration, disinfection, etc. ), its water quality is drinkable.

Class III water quality: it is suitable for centralized drinking water source secondary protection zone, general fish protection zone and swimming zone.

Class IV water quality: suitable for general industrial protection zones and recreational waters where human body is not in direct contact.
