How can we use the sun’s energy to clean our water of hazardous materials? This summer, I have had the opportunity to study that question working in the labs at the Universidad de Puerto Rico Mayagüez (UPRM) doing research in the Civil Engineering Department, specifically in the Environmental area, under the mentorship of graduate student Alba Lacen and the advisement of Dr. Pedro Tarafa. There are a variety of dangerous chemicals that get into our water from many sources and removing pollutants becomes a problem for wastewater treatment plants to handle. Atrazine, an organic compound, is one such substance. Atrazine is a potent endocrine disruptor in humans and animals alike.
