Good water quality from municipal wastewater treatment plants is critical to public health and safety.  A growing concern is the increasing use of additives to food and personal care products that ultimately enter the sewage systems and may affect these treatment plants.  One of the more common of these additives is titanium dioxide (TiO2), which is often added as tiny particles to whiten foods, toothpastes, sunscreen, and skin care products.  The estimated global annual production of TiO2 is about 85,000 tons. The ubiquity of TiO2 in personal care products means that a significant portion is washed down the drain (for example, using toothpaste to clean teeth or washing lotions off through showering). This Citizen Science project is a partnership with the Madison Metropolitan Sewerage District and the University of Wisconsin - Madison to study TiO2 entering the wastewater treatment plant through personal care product usage.  Information is being collected from citizen scientists to inventory the amounts of TiO2 in consumer products by household. This information is then being used to model TiO2 entry into the wastewater treatment plant and to determine how detrimental this may be to water quality and the environment.This research project is generating the first household level inventory of TiO2 enabled consumer products and determining whether the quantity of TiO2 entering the wastewater treatment plant is sufficient to cause concern and potential treatment disruptions. This research integrates citizen scientists in a two-way flow of information and will determine potential solutions for the entry of TiO2 into the treatment plant and eventually the environment (through effluent from the treatment plant and agriculturally utilized biosolids). This work is determining if TiO2 from personal care products is a major route of TiO2 entering the environment. This research also has implications from a policy standpoint, in particular with respect to future regulation of TiO2. The specific objectives of the proposed work are: 1) Create a household relevant inventory of TiO2 containing personal care products based on citizen scientist responses, 2) Model the TiO2 entering the treatment plant and eventually discharged to receiving waters as a function of the household profiles, and, 3) Hold a citizen scientist roundtable meeting, to present the results of the study, and gain insight from the citizens into future solutions. The Citizen Scientist Roundtable meeting will be held after the completion of the inventory and modeling stages of the proposed work. The residents of the Madison Metropolitan Sewerage District service area who complete the survey will be invited to the roundtable discussion. A version of the model will be available for the citizen scientists to use.

市政废水处理厂的良好水质对公共卫生和安全至关重要。越来越多的关注点是，添加剂越来越多地用于食品和个人护理产品，这些食品和个人护理产品最终进入污水处理系统并可能影响这些治疗厂。这些添加剂中最常见的一种是二氧化钛（TIO2），通常将其添加为白色食物，牙膏，防晒霜和皮肤护理产品的微小颗粒。 TiO2的全球年度产量估计约为85,000吨。 TIO2在个人护理产品中的无处不在意味着将大部分部分冲洗到排水沟中（例如，使用牙膏清洁牙齿或通过淋浴清洁乳液）。该公民科学项目是与麦迪逊大都会下水道区和威斯康星大学 - 麦迪逊分校的合作伙伴关系，可以通过个人护理产品使用量来研究进入废水处理厂的TIO2。正在从公民科学家那里收集信息，以库存家庭消费产品中TIO2的量。然后，该信息被用于模拟TiO2进入废水处理厂，并确定该信息对水质和环境的确定是如何确定的。本研究项目正在生成第一个家庭水平的TIO2库存，使TIO2促进消费产品，并确定进入废水处理厂的TIO2数量是否足以引起关注和潜在的治疗干扰。这项研究将公民科学家整合到了两条信息流中，并将确定将TIO2进入治疗厂乃至环境的潜在解决方案（通过从治疗厂和农业利用的生物固醇生效）。这项工作是确定个人护理产品的TIO2是否是进入环境的TIO2的主要途径。从政策的角度来看，这项研究也具有含义，特别是关于未来TIO2的监管。拟议工作的具体目标是：1）创建一个基于公民科学家反应的个人护理产品的家庭相关库存，2）模拟Tio2进入治疗厂，并最终将其作为家庭概况的函数，以及3）举行一场公民科学家圆桌会议，以呈现研究结果，以呈现研究的结果，并呈现出未来的公民，并获得了公民的洞察力。公民科学家圆桌会议将在拟议工作的库存和建模阶段完成后举行。完成调查的麦迪逊大都会下水道地区服务区的居民将被邀请进行圆桌讨论。该模型的版本将供公民科学家使用。
