Water Detectives of Cowiche Creek
H ighland High School is a public high school surrounded by orchards in the foothills of the Cascade mountains.
Highland researchers conducted a series of water quality tests on a local creek in 1996 and 1997. They found that flooding in 1997 did affect the water quality of Cowiche Creek. The water had a higher level of Ammonium Nitrate due to an increase in agricultural runoff.
Research Question: How does the water quality of a stream change over time?
Pili: We have worked on this project for two years now. It was difficult sometimes to find the time to take the samples. We tested water quality using a testing kit.Angie:We also tested the soil quality. We found that very deep, well-drained soil is on the uplands. Permeability of this soil is moderate. The available water capacity is high. Runoff is medium, and the hazard of water erosion is moderate.

"Many Hispanic people think they can't be good in science. I thought I
couldn't, but I can. Sciences seem hard at first, but the program
us, and we've found out that girls can do sciences too."
