Table S1 water quality criteria in China (GB 3838-2002)

Grade1 / COD(≤mg/L) / NH3-N(≤mg/L) / FC(≤ CFU/L) / Designated Uses
I / 15 / 0.15 / 200 / Water sources and national nature reserves
II / 15 / 0.5 / 2000 / Primary reserve zones providing centralized domestic and drinking water; habitats of rare aquatic; Spawning grounds of shrimp; Feeding grounds of larvae larval.
III / 20 / 1.0 / 10000 / Secondary protection zone providing centralized domestic and drinking water; Wintering grounds of shrimp; Migration pathway; Aquaculture, fishing and swimming areas.
IV / 30 / 1.5 / 20000 / General Industrial water zones and water recreation areas where no direct contact with humans occurs.
V / 40 / 2.0 / 40000 / Agricultural water zones and scenic water areas.

I-the best, V-the worst.

Multi-purpose water zones are classified based on their primary function. Seasonal water zones are classified based on a seasonal basis.
