Field surveys on water and sediment in open channels and drainage ditches that receive Johkasou effluents to assess the impact ofJohkasou on the local water environment. Concentrations of general water quality parameters in the drainages receiving the effluents directly were at high level, but no significant effect was observed on both concentrations in water and spices of bacteria in bed sediment or biofilms. Contents of E. coli or a bacteriophage in sediment increased at the point after conjunction of the drainage, suggesting that the channel possibly has a function of retention of them.

对接受Johkasou污水的明渠和排水沟的水和沉积物进行实地调查，以评估Johkasou对当地水环境的影响。直接接受污水的排水系统中的一般水质参数的浓度处于较高水平，但没有观察到显着的影响，无论是在水中的浓度和细菌的种类在床沉积物或生物膜。E.大肠杆菌或噬菌体在连接排水后的沉积物中增加，这表明通道可能具有保留它们的功能。
