The basic ground surface water includes rivers,lakes,canals, channels, reservoirs, etc.it need to measure around 40 water quality parameters based on different site,such as pH, dissolved oxygen,turbidity,Blue-green algae,suspended solid,Chlorophyll,conductivity, ammonia nitrogen, COD,BOD,total phosphorus, permanganate index, lead, fecal coliform,total Iron ,total manganese etc
Ground surface water has big impact for safety of drinking source water and seriously threatens people's health in every country.another side,the quality of drinking is directly reflects the civilization level of a country. Every country must strengthen the management of ground surface water, prevent water pollution and protect human health.because this is about the future
For the toxic organic pollutants that are difficult to remove by conventional treatment methods and which are extremely harmful, they must be highly valued by relevant departments, and organize more comprehensive and systematic monitoring investigations and research in the country as soon as possible so as to timely formulate preventive measures.
