Objective
The objective of this project is to investigate: does watering with recycled water affect the safety of school lawns?
Hypothesis: I think that watering with recycled water does not affect the safety of school lawns.
Experimental Procedure
I grew three patches of lawn in three separate miniature greenhouses using plastic boxes, chicken wire, and clear plastic trash bags. I watered one with recycled water, one with distilled water, and the other container with tap water. I measured their growth rate and compared the appearances of the grass patches in each container. I collected water runoff samples and tested each for pathogens, nutrients, and other characteristics.
