The Ministry of Environmental Protection said in a notice that 70 percent of surface water samples tested in the first six months of 2017 qualified as grade I to III, meaning it was clean enough for direct human use - up 1.2 percentage points compared to the same period of last year.
China ranks its water supplies in six bands. Grade IV refers to water that is "lightly polluted" but can still be used for ordinary industrial purposes, while Grade V is suitable only for agricultural use.
In the first six months of 2017, samples in the lowest "below-V" grade, which refers to water that is so polluted that it has "lost function", fell 1.7 percentage points to 8.8 percent, the ministry said.
However, the ministry also listed 27 sampling sites that saw water quality decline in the first six months of the year, including sites in Hebei, Shanxi, Shandong, Liaoning and the capital Beijing, where a third of tested samples were judged to have "lost function".
Five regions - Inner Mongolia, Heilongjiang, Jiangxi, Guizhou and Shaanxi - also saw their amount of "below-V" samples increase over the period.
