Current Research
Disinfection Bi-products (DBPs) in Drinking Water
All drinking water, including Columbia tap water, has been known to contain some level
of disinfection bi-products. DBPs are toxic results formed from disinfectants used
in the water disinfection process with the natural organic matter in the water. This
project specifically focuses on plant uptake of these DBPs. This experiment takes
place in our greenhouse where 3 hydroponic systems are used to grow Basil: one with
purified spring water, one with pure water spiked with controlled concentrations of
3 DBPs (iodoacetic acid, dibromoacetic acid, and dichloroacetic acid), and one with
Columbia tap water.
Chlorella vulgaris
Chlorella vulgaris is a microalgae that has been shown to be a very effective growth
adjuvant in tomatoes, lettuce and strawberries, boosting yields by 50% and greatly
extending the shelf life of products. This project will help determine how and if
algae improve growth rates of tomatoes and kale. The experiment will be set up in
our greenhouse during the Fall 2020 semester and will run through the Spring 2021
semester.
Past Research
Permeable Concrete
Come take a walk through the garden and you will notice our unique stepping stones
that were made using permeable concrete and designed to help with water runoff and
mitigate soil erosion. Pervious concrete pavement is a unique and effective means
to address important environmental issues and support sustainable growth here on campus.
By capturing stormwater and allowing it to seep into the ground, porous concrete is
instrumental in recharging groundwater and reducing stormwater runoff. In fact, the
use of pervious concrete is among the Best Management Practices (BMPs) recommended
by the EPA for the management of stormwater runoff on a local basis.
Outdoor Classroom
The goal of this project was to assess students’ performance in traditional classrooms
versus an alternative learning environment. Student performance was based on the criteria
of attendance, engagement, motivation, and emotional well-being in the two different
classroom environments. The results added to our understanding of alternative classroom
environments and their effect on students’ performance, and thus support the possibility
of building a permanent outdoor classroom on campus.

Water Filtration System
The water filtration system in the Garden captures rainwater and filters it into purified
drinking water for Garden volunteers. Rainwater is captured from the Green Quad C
building, stored in a rain barrel, then passes through a biosand filter and Berkey
water filter. A biosand filter is a point-of-use water treatment system adapted from
traditional slow sand filters. Biosand filters remove pathogens and suspended solids
from water using biological and physical processes that take place in a sand column
covered with a biofilm.
