对辖区集中式供水水质的监测，结果发现，国铁组供水水质的大肠菌群合格率为３８．５％；地铁组为８４．０％。两组相比有显著性差异（Ｐ＜０．００５）。供水水质中大肠菌群合格率偏低，应引起有关部门的重视，做好供水水质的消毒工作，防止生物性污染仍然是铁路沿线站区饮水卫生的重要任务。
The monitoring of centralized water quality in the area showed that the passing rate of coliform bacteria of the water quality of the Guotie Group was 38.5% and that of the Metro Group was 84.0%. There was a significant difference between the two groups (P <0.005). The passing rate of coliform bacteria in water quality is low, which should be paid more attention by the relevant departments. Disinfection of water quality should be done well. Preventing biological contamination is still an important task of sanitation of drinking water along the railway station.
