The Wikipedia article “Water Treatment” is rated as a C-Class article of Low-importance. The article briefly covers the definition, various types of water treatment, and its history as well as provides miscellaneous information about water sanitation around the world. However, the overall article lacks organization as well as specific information that details the processes and uses of water. Although the article does provide a variety of different headings, the connection between each heading and the overall purpose of the article is not clear. For example, the significance of Portable water purification, Ultra pure water production, Energy consumption, along with other headings, to the overall topic is not explained, which causes much confusion. Furthermore, the information within each heading is very underdeveloped. For example, the Biochar heading is comprised of only two sentences, with barely meaningful information provided. Besides having some problems with the already-included topics, there are some other aspects of water treatment that need to be included and elaborated on. These include irrigation, public health, and river flow. These topics should be included because they are directly related to water treatment and are essential to understanding it.

Although this article is ranked as Low-importance, the fundamentals of this topic play an integral role in Sustainable Development Goal 6 (SDG6) of “ensuring access to water and sanitation for all.” SDG6 is trying to address the problem that “billions of people still lack safe water, sanitation and handwashing facilities,” which involves water quantity and quality. The latter part is closely interrelated to water treatment, which is essential to resolving contamination and providing sanitation. This article has the potential to educate citizens and governments on water treatment and the various different topics revolving around it, could be used to improve sanitation and increase access to clean water.
