The US Environmental Protection Agency's (USEPA's) Water Security Test Bed (WSTB) facility is a full‐scale representation of a drinking water distribution system. In collaboration with the Idaho National Laboratory, USEPA designed the WSTB facility to support full‐scale evaluations of water infrastructure, premise plumbing, and appliance decontamination. Thus far, USEPA's research has focused on decontamination of Bacillus globigii (BG) spores, a nonpathogenic surrogate for Bacillus anthracis, and Bakken crude oil. Flushing and disinfection effectively removed 7–8 log₁₀ BG spores from the bulk water, but only 2–3 log₁₀ from the pipe wall coupons. Bakken crude oil components were removed from distribution pipe and premise plumbing water by flushing, although 55% of the injected oil components persisted in the dishwasher and refrigerator water dispenser. Using the WSTB facility allows USEPA to test contaminants without any human health or ecological risk and to inform water systems on effective methodologies for responding to contamination incidents.

在水安全测试床上进行全面的饮用水系统净化处理。

美国环境保护署（USEPA）的水安全测试床（WSTB）设施是饮用水分配系统的全面代表。USEPA与爱达荷州国家实验室合作，设计了WSTB设施，以支持对水基础设施，房屋管道和设备净化的全面评估。迄今为止，USEPA的研究集中于去污芽孢杆菌 （BG）， 炭疽芽孢杆菌和Bakken原油的非致病性替代物。冲洗和消毒有效地从大量水中去除了7–8 log ₁₀ BG孢子，但仅清除了2–3 log ₁₀从管壁优惠券。尽管有55％注入的机油成分残留在洗碗机和冰箱的饮水机中，但仍通过冲洗从分配管和室内管道用水中去除了粘稠的原油成分。使用WSTB设施可以使USEPA在没有任何人类健康或生态风险的情况下测试污染物，并为水系统提供应对污染事件的有效方法的信息。
