Only about 2.5–3% of the world’s water is freshwater. I have always taken it for granted, until I saw how much others struggle to access it. In my IB Spanish class, for the topic “cómo compartimos el planeta”, I learned about deserts like the Atacama flooding, wetlands like Laguna Tisma in Nicaragua having drought, and towns like La Oroya in Peru polluted with tin, lead, and cadmium. Visiting India over breaks, I noticed dust and pollution covering small villages and cities like Hyderabad. These glimpses made me realize how unevenly water is distributed and how urgently science and engineering are needed to protect it.
I have loved science and engineering for as long as I can remember. My high school’s IB program gave me four years of biology, three of chemistry, two of physics, and two of studying materials science for Science Olympiad. This year, I did not plan to dive into Water Quality because identifying bugs is part of the event, and I am not exactly comfortable with them. But, I ended up fascinated with the other part, which involved monitoring and analyzing water. Learning how salinity, pH, phosphates, dissolved oxygen, nitrates, total solids, alkalinity, turbidity, temperature, fecal coliform, and biochemical oxygen demand all interconnect, and how freshwater macroinvertebrates can act as indicators for water quality, really got me intrigued.
Due to this, I convinced my friends to do water quality for our IB Collaborative Sciences project. We got to collect data from the local Millstone River during a canoeing trip, using real water testing tools like pH probes and salinometers. Later, we compared our readings to accepted standards, proposed potential causes such as fertilizer runoff making the stream slightly too acidic, and suggested solutions like riparian buffers or phosphate-free fertilizers. Even on this small scale, it was amazing to see how the science I learned so recently could help guide real improvements in our local environment.
Later, in my bioengineering class, I worked on another project by studying the Diamond Alkali Superfund site on the Passaic River in Newark, New Jersey. The site is contaminated with dioxins and PCBs, and we studied the previous containment plan before designing our own approach. We ended up with a plan including a natural oil emulsion to capture lipophilic dioxins in microspheres that could be skimmed off, followed by filtration with coagulants, granular activated carbon, and UV light. This project taught me about more innovative and novel ways to treat water.
These experiences have cemented my dream of studying chemical or civil engineering, and continuing to pursue water quality at the heart of my work. Whether addressing local Superfund sites in New Jersey, working in wastewater treatment, or exploring other areas like hydraulic modeling or flood control, I hope my work will contribute to better water quality testing practices, reduced waterborne diseases, and assistance to future generations in protecting this limited, precious resource. Science has given me tools, but more than that, it has shown me that curiosity, care, and persistence can make the world healthier and more sustainable for the people and ecosystems that depend on it, now and long after I am gone.
