Abstract:
Water quality surveillance systems are hardly applied in rural contexts. To provide a comprehensive analysis of drinking-water quality in two rural settlements in the Colombian Caribbean drinking-water samples were collected and analyzed from storage containers in 42 homes. The results of physical, chemical, and microbiological analyses of the water samples were compared with values established by the World Health Organization (WHO) Guidelines for Drinking-water Quality, and Colombian regulations. The Kruskal-Wallis test was applied to compare each parameter for supply source, season (rainy or dry), settlement, and types of storage. Drinking-water Quality Risk Index (IRCA) was calculated for each of the samples. The water supply sources were varied: well (33.3%), rainwater (23.8%), artificial pond (23.8%), and river (19.0%). One-hundred percent of the samples contained Escherichia coli and total coliforms. The IRCA varied between 57.3 and 83.9, with a median of 72.9. Eighty-eight percent of the samples exhibited high risk levels (35.1 < IRCA < 80.0) and 12% were unsanitary (80.1 < IRCA < 100.0). Artificial pond water was the source of supply with the worst IRCA (83.79). Drinking water in the El Cascajo and La Delfina settlements does not meet international and national drinking-water standards. A change is required whereby monitoring and quality control policies take into account the reality of rural settings.
摘要:
水质监测系统几乎不适用于农村环境。为了全面分析哥伦比亚加勒比两个农村居民区的饮用水质量,从42个家庭的储存容器中收集并分析了饮用水样本。物理的结果,化学,水样的微生物学分析与世界卫生组织(世卫组织)《饮用水质量指南》确定的值进行了比较,和哥伦比亚法规。Kruskal-Wallis测试用于比较供应源的每个参数,季节(多雨或干燥),结算,和存储类型。计算每个样品的饮用水质量风险指数(IRCA)。供水来源多种多样:井(33.3%),雨水(23.8%),人工池塘(23.8%),和河流(19.0%)。百分之百的样品含有大肠杆菌和总大肠杆菌。IRCA在57.3和83.9之间变化,中位数为72.9。88%的样本表现出高风险水平(35.1
