SLEWS Field Day at Central Valley High School Farm Focuses on Water Conservation

By: Chanin Eredia, Director of Education

Students from Central Valley High School recently participated in a SLEWS (Student and Landowner Education and Watershed Stewardship) field day focused on water conservation and water quality. The hands-on event connected soil science and watershed stewardship to real-world practices used in agriculture and conservation throughout the Central Valley.

During the field day, students conducted two important water-focused tests used to better understand soil health and water quality. The first activity explored water infiltration. Using infiltration rings, students measured how quickly water moved through the soil and observed how soil structure and compaction affect the soil’s ability to absorb water. This activity helped demonstrate why healthy soils are critical for conserving water, reducing runoff, and protecting water quality.The second activity focused on water pH testing. Students tested the pH levels of both bottled water and tap water using simple field testing kits. This allowed them to see how water sources can vary and opened up conversations about water quality, chemistry, and how pH can influence soil, plant health, and aquatic systems.

Field days like this give students the opportunity to learn by doing while building a stronger understanding of how soil and water systems work together. Through the SLEWS program, students gain hands-on experience that connects science, agriculture, and conservation in ways that are meaningful for our local community and environment.
