Turning Greywater Green

CSEF · 2011 Plant Biology

Selma E. Kondoker · CA Virtual Academy, Riverside, Riverside County

Overview

Objectives/Goals The purpose of this experiment is to determine if plants watered with greywater will grow better than plants watered with tap water. Methods/Materials A total of sixteen plants were grown. There were four different types plants, each type of plant referred as a plant group. Two plants form each plant group were watered with tap water (control gorup), and two plants from each plant group were watered with greywater. The height of plants were measured and averaged to one height every day. The control plants' heights were compared to the greywater plants' heigths. Results The results show that plants watered with greywater grew taller than the plants watered with tap water. Grewywater contains soap residue, which consists of nutrients like nitrogen, potassium, and phosphorus which can fertilize plants and help them grow tall. Conclusions/Discussion Greywater could be used water plants.

Summary statement

Greywater can be green.
