To assess the microbial water quality of harvested rainwater infrastructure used to supplement household water uses for homegrown produce.
Using a co-created community science methodology, between 2017 and 2020, a total of 587 harvested rainwater samples and 147 garden soil samples irrigated with harvested rainwater were collected from four Arizona communities and analyzed for coliform, Escherichia coli, and/or Salmonella. Participants also completed a home description survey regarding their home and surrounding area, water harvesting infrastructure, and gardening habits.
Chi-Square tests revealed that the quality of harvested rainwater is affected by proximity to a waste disposal or incineration facility, animal presence, cistern treatment, and cistern age (P < 0.05), while soil samples were associated with community (P < 0.05). Coliform and E. coli concentrations in both sample types were greater in the monsoon season.
评估用于补充家庭自用作物的家庭雨水采集基础设施的水质微生物状况。
使用共同创造的社区科学方法，在 2017 年至 2020 年间，从亚利桑那州的四个社区共采集了 587 个雨水采集样本和 147 个用雨水灌溉的花园土壤样本，对大肠菌群、大肠杆菌和/或沙门氏菌进行了分析。参与者还完成了一份关于他们的家庭和周围环境、雨水采集基础设施和园艺习惯的家庭描述调查。
卡方检验显示，雨水采集的质量受到与废物处理或焚烧设施、动物存在、蓄水池处理和蓄水池年龄的接近程度的影响（P<0.05），而土壤样本则与社区有关（P<0.05）。两种样本类型中的大肠菌群和大肠杆菌浓度在季风季节更高。
