Linkous 1 Amy D. Linkous Katie Fallon English 1106 March 17, 2008 Critical Analysis of a Source The source in question is a report by a team of scientists from Sandia National Laboratories titled “Ultraviolet Water Purification Systems for Rural Environments and Mobile Applications.” It is a PDF file that, when more closely examined, seems to have been printed on paper as well. The general topic of this academic journal style formal report is “the results of a one year LDRD (Laboratory Directed Research and Development) program that has focused on evaluating the use of newly developed deep ultraviolet LEDs (Light Emitting Diodes) in water purification” (Crawford et al. 3). What this means is that this team of scientists developed a newer ultraviolet light purification system for water and tested it out for one year. They made note of the effectiveness of the system at killing the E-Coli virus as well as studying the practicality of using it not only as a mobile purification system, but as a permanent solution in rural areas. Their report was published in November of 2005, meaning that this article is recent enough to be used (if it is credible). The ultimate goal of the scientists’ work is to educate the reader about the ultraviolet purification system’s effectiveness and also to push forward the idea of using this system in many areas of the globe in the future. It is structured quite nicely. There is a title page and contact information, followed by the departments each scientist works in and a brief abstract of the report itself. Right after this are acknowledgements to others who did not

Linkous 2 actually help write the article but who made significant contributions to its composition. Separate tables of contents are given for text, figures and tables, then an introduction is presented and the real report begins. The way they chose to organize the actual report was to combine relevance and chronological order. The paper partially progresses with their studies, but transitions smoothly from one specific aspect of the project to the next. There is a “Conclusions” section followed by an entire page of references. Just the fact that they cited all those sources helps their credibility.
