课程名称：水中有什么？它来自哪里？ 课程概述：在这部9部分的视频系列中，霍格伦博士讨论了水的基本化学成分以及这些成分所指示的水的来源（即其起源）。他提供了关于南加州水源的视角以及水资源管理方面的问题。本课程是由霍格伦博士创立的非营利组织“碳负水和能源”开发的。如果您从中受益，考虑做出捐赠；如果您是那98%无法捐赠的人，请大力转发该网站和课程信息给您的网络，这将有所帮助。 南加州的水主要来源于三个方面： aqueducts（水渠）、地下水和海水淡化。地下水资源由山上流出的“径流”以及在沿河渠道和溢流堤内人工补充的水组成。海水淡化技术则用于将废水处理成淡水，再将其注入地下水系统，形成“海水屏障”，提高淡水地下水位，形成“地下水丘”，抑制海水从海洋向内陆的渗透。 所有水的输送和管理都需要消耗能量。海水淡化在能耗方面已与水渠抽水能耗具有竞争力，成本也变得具有竞争性。因此，海水淡化正日益成为满足南加州饮用水需求的重要供应来源。 课程内容如下： 第一部分：离子 第二部分：溶解固体和生物影响 第三部分：可能的化学和放射性污染物 第四部分：水中的能量？水源比较 第五部分：橙县地下水管理 第六部分：海水淡化与海水屏障 第七部分：水渠概述 第八部分：洛杉矶水渠 第九部分：加州和科罗拉多河水渠及其在橙县的输送 通过本课程，学员将对水的来源、组成及管理有更深入的理解。
In this 9 part video series, Dr Hoaglund discusses general water chemistry and what it indicates about the water's origins, also known as its provenance. He then provides a perspective on water sources for Southern California, and the issues surrounding water management. This course was developed as part of the mission of the non-profit Carbon Negative Water and Energy founded by Dr. John Hoaglund.

The groundwater resource is comprised of "runoff" from the mountains, as well as aqueduct water that is "artificially recharged" into the groundwater system in spreading basins, constructed within the river channels and overflow banks. Desalination is used to treat waste water into freshwater, which is then put into the groundwater system to form "seawater barriers," raising fresh groundwater levels in a "groundwater mound" that inhibits "saltwater encroachment" from the ocean. All of the deliveries of water and its management requires energy. Desalination of seawater has become energetically competitive with aqueduct pumping energy, enough to be cost competitive. As a result, ocean desalination is becoming an increasing supplier of southern California's potable water needs.Part I: IonsPart II: Dissolved Solids and Biological ConsiderationsPart III: Possible Chemical and Radiological ContaminantsPart IV: Energy in Water?
