Urban Storm Water: Dr. Matiasek’s Student Team Develops Sustainable Storm Water Filters

Dr. Sandrine Matiasek was awarded Phase 1 and Phase 2 grants from the U.S. Environmental Protection Agency (EPA) to lead an interdisciplinary team of CSU, Chico students to research and develop sustainable biofiltration technology for small urban areas like Chico. 

The CSU, Chico team is comprised of six students majoring in civil engineering, chemistry and environmental science: Harry Mills, (Chemistry), Sophia Bauer (Environmental Science), Spencer Carroll (Environmental Science), Mark Triassi (Environmental Science), Autumn Reagan (Civil Engineering) and James Norris (Civil Engineering).

Using the CWE laboratory as the staging ground for their research, the students are developing green methods for filtering urban storm water runoff in order to reduce the impact of sediments, pesticides, metals and other pollutants on local aquatic ecosystems.

"Biofiltration is a really relevant area of research and a promising, sustainable solution for dealing with urban storm runoff, especially up here in the North State where we deal with strong storm events in the winter,” said Sandrine Matiasek, CWE Faculty Associate, Assistant Professor in the Department of Geological and Environmental Sciences, and Principal Investigator for this project.

According to the project abstract, titled “Evaluating Biofiltration in Small Urban Areas: Chico, California Case Study,” the team plans on testing the effectiveness of biofiltration using sand, compost, lava rock, zeolite (an absorbent mineral), and native, drought resistant plants. Matiasek said that their research explores relatively new territory in regards to testing and adapting sustainable filtration processes.

“What this project is trying to do is bring in science to back up this new solution to dealing with storm runoff," Matiasek said. “The goal is to fill in a gap in knowledge. Large urban areas are already required to deal with storm runoff. So far, it hasn't really been implemented for small urban areas because of cost."

Matiasek added that on top of gaining experience in biofiltration research, the student team is also partnering with local organizations to develop its design. The students research team is supported by Center for Water and the Environment on campus, with support from Facilities Management Services to acquire soil samples. They are presenting their research results at This Way To Sustainability Conference 2018
