Lake area: Over the past 30 years, pollution has the rapid growth trend. Such as Dianchi Lake, the water quality of the whole lake water below the V class of nitrogen and phosphorus pollution is serious, eutrophication prominent problem.
Marine areas: serious pollution manifested in the increased frequency of occurrence of red tide and flooding in these areas.
Groundwater aspects: 30% of the national urban water supply from groundwater, the northern city of up to 89%, nearly 20 cities in the deterioration of groundwater quality
