Due to human error, drinking water supplied to a new housing estate in The Netherlands was contaminated with grey water. The cohort of 921 accidentally exposed households (area A) had a higher attack rate for diarrhoea (54.1%) than a non-exposed cohort of 1529 households from an adjacent area (B) (24%) (RR 2.3, 95% CI 1.9-2.7). Household water score showed a dose-response with illness, in both areas A and B. For each 1000 inhabitants, 19.8 cases in area A, 7.0 cases in control area B (RRAB 2.2, 95% CI 1.3-3.8) and 3.3 cases in a more distant control area C (RRAC 4.6, 95% CI 2.7-8.0) were diagnosed with gastroenteritis by their general practitioner. A gastroenteritis outbreak associated with consumption of contaminated drinking water was observed in the exposed area. The use of grey water was banned in 2003, with the exception of rainwater use for flushing toilets. The risk of rainwater use is currently being investigated.
由于人为失误，荷兰一个新建住宅区的饮用水被中水污染。921户意外暴露家庭（A区）的腹泻发病率（54.1%）高于相邻区域（B区）1529户未暴露家庭（24%）（相对危险度2.3，95%置信区间1.9 - 2.7）。家庭用水评分在A区和B区均显示出与疾病的剂量反应关系。每1000名居民中，A区有19.8例、对照B区有7.0例（A区与B区相对危险度2.2，95%置信区间1.3 - 3.8）、更远的对照C区有3.3例（A区与C区相对危险度4.6，95%置信区间2.7 - 8.0）被全科医生诊断为肠胃炎。在暴露区域观察到一起与饮用受污染饮用水相关的肠胃炎暴发。2003年除雨水用于冲厕外，中水的使用被禁止。目前正在调查使用雨水的风险。
