1361678ChowThe Yosemite Rim fire, the third largest fire in California, burned 257,314 acres (402 square miles) adjacent to a major source of drinking water for 2.6 million people. This fire burned for nearly 10 weeks and was reported 100 % contained October 26, 2013. The research team has already collected the first set of samples which are post-fire and pre-rain. The next sampling will be post-rain as close to initial runoff as possible. One of the big questions is how did this fire affect the water quality of the reservoirs in and around Yosemite National Park and what might be the impact subsequently on drinking water quality. The burning will likely increase the concentration of chemicals controlled under the Safe Drinking Water Act, namely polynuclear aromatic hydrocarbons (PAHs). However; little to no information is known on the potential formation of black carbon, soot to most of us, and its impact on water quality or drinking water quality. Another unknown is the impact of the fire on natural organic matter from the forest floor. This organic matter from "leaf litter" is normally transported to streams, rivers and lakes by rain and it may lead to the formation of disinfection by-products during water treatment. The impact of fires on this organic matter is unknown and because the waters in the surrounding area are the source of drinking water it may affect drinking water quality. Through the association of the PIs with California Department of Fish and Game and the CA State Water Resources Control Board material will be developed for use by the Agencies education and outreach programs.

约塞米蒂林缘大火是加州的第三大火灾，烧毁了257，314英亩（402平方英里），毗邻260万人的主要饮用水源。 这场大火燃烧了近10周，据报道，2013年10月26日100%被控制。 研究小组已经收集了第一批火灾后和下雨前的样本。 下一次采样将在雨后尽可能接近初始径流。 其中一个大问题是，这场大火如何影响约塞米蒂国家公园内和周围水库的水质，以及随后可能对饮用水质量产生的影响。 燃烧可能会增加受《安全饮用水法》控制的化学品的浓度，即多环芳烃（PAH）。 然;关于黑碳（对我们大多数人来说是煤烟）的潜在形成及其对水质或饮用水质量的影响，几乎没有任何信息。 另一个未知数是火灾对森林地面天然有机物的影响。 这种来自“落叶”的有机物通常通过雨水进入溪流、河流和湖泊，在水处理过程中可能形成消毒副产品。 火灾对这种有机物的影响尚不清楚，因为周围地区的沃茨是饮用水的来源，它可能影响饮用水的质量。 通过PI与加州渔业和狩猎部以及加州水资源控制委员会的联系，将编写材料供机构的教育和推广方案使用。
