Pollution is a serious problem in Chingching because although it is a protected water source area, only two or three of its almost 100 guesthouses have wastewater treatment systems. What's more, most of them draw water illegally from springs on Mt. Hehuan, which is not just an eyesore but also impairs water intake.
據瞭解，位於水源保護區內的近百家清境民宿中，只有二、三家有廢水處理裝置，污染問題嚴重；再加上大部分民宿都私接合歡山的山泉水，不僅影響觀瞻，上游的取水口也因此遭到破壞。
