In January 2012, Health Canada released its review on the health risks associated with "Enteric Protozoa: Giardia and Cryptosporidium" in drinking water. A key component of this is Quantitative Microbial Risk Assessment (QMRA). Enteric protozoa are specifically of concern when maintaining microbial drinking water quality and subsequently in QMRA models, because chlorination has low/no inactivation effect on them (e.g. Cryptosporidium). The partner, the City of Ottawa, is proactive in its drinking water treatment practices and has worked with Health Canada in developing frameworks for integration of QMRA into drinking water treatment decision-making. They are interested in obtaining critical data so that they can better utilize QMRA to manage treatment operations and minimize public health risk from disease causing organisms. Specifically,

2012年1月，加拿大卫生部发布了关于饮用水中“肠道原生动物：贾第虫和隐孢子虫”的健康风险的审查报告。其中一个关键组成部分是定量微生物风险评估(QMRA)。肠道原生动物在维持微生物饮用水质量时和随后的QMRA模型中尤其令人担忧，因为氯化对它们的灭活效果很低或没有影响(例如隐孢子虫)。合作伙伴渥太华市政府在饮用水处理实践中积极主动，并与加拿大卫生部合作，制定框架，将QMRA纳入饮用水处理决策。他们对获得关键数据感兴趣，这样他们就可以更好地利用QMRA来管理治疗操作，并将致病微生物带来的公共健康风险降至最低。具体来说，
