The passing rate of finished water was obviously higher than that of tap water. The passing rates of finished water and tap water had no significant difference between dry and wet season. Microbial indicators were the major indicators which exceeded the standard. The overall passing rate of centralized water supply projects in rural areas was 40%. Conclusion Centralized water supply was the main way of rural areas in Handan.
