The importance of water should never be understated! It is a vital component of all life-sustaining processes and integral to chemical reactions. The human body is made of up nearly 60-70% water by body weight, with a decrease of 4% causing dehydration and losses of 15% becoming life-threatening or fatal. Drilling down further, water is considered a universal solvent, it plays an important structural role in our cells as it regulates their shape based on water concentration in various environments and facilitates biochemical reactions by being directly involved in dehydration synthesis and hydrolysis reactions. And this is only at the cellular level. As water crises and droughts highlight the lack of consistent water access around the globe, we know that water is essential for life.
Our Headwaters Research Experience students recognize the importance of water quality to aquatic systems, and we help students create projects centered around the analysis of water quality in their neighborhoods and watersheds. These types of water quality studies are simple to conduct, but can yield impactful results and raise awareness among local community members.
Ethan Liu was curious about water in NYC and focused on comparing water quality between the neighborhoods of Chinatown and Bayside, which have a sizable difference in average household income. Ultimately, Ethan found that there was no significant difference in pH or total dissolved solids (TDS, like inorganic salts and some organic matter) for water sampled from restaurants in these regions. Ethan, and the community members who allowed him to sample their water, were reassured by his findings.
Ethan’s presentation is the first of our student presentations featured here if you’d like to learn more:
Katie Chen wanted to research the effects of fertilizer on the water quality of Saratoga Creek. Many land managers use fertilizers to increase crop yields, but nitrogen runoff can cause significant damage to the watershed and harm water quality in the area. Through her experimental research design, Katie found that the fertilizer significantly reduced the pH and increased the TDS of Saratoga Creek water. Katie did a great job designing, conducting, and analyzing her research and the Journal of Emerging Investigators accepted her write up for publication!

This week for Headwaters’ Back to School Fundraiser, we’re highlighting water! Donating to Headwaters helps us plan and run the Research Experience and students like Ethan and Katie pursue projects that impact their communities and contribute to science. Your support also helps us provide Lunch with a Scientist talks, like Dr. Tonya Shearer’s on coral reef health, to students around the country. Thank you!
