Water Quailty Scifair Projects

Water Quality

Water quality can be impacted by a number of factors. Some factors are natural and some are introduced by human activity.

Objectives/Goals

Water and Soi Microbes Science Fair Projects.Our objective is to monitor the water quality of the San Lorenzo River in Felton specifically levels of nitrate, turbidity and dissolved oxygen in addition to water velocity and temperature. Our hypothesis is that the river will maintain acceptable levels of these factors, but naturally fluctuate due to rainfall and human impacts.

Methods/Materials

In the field, we use a Vernier Lab Pro, graphing calculator and assorted probes to measure our parameters. We are comparing two sites along the river, Henry Cowell State Park entrance and the Felton Covered Bridge. At our two sites (every Sunday at 8 AM from Nov 07 to Feb 08), we collected our water sample, made observations, calibrated our equipment and performed water testing procedures.

Results

We have found all of our results to be in the healthy range.

Conclusions/Discussion

We are currently analyzing our results to correlate rainfall data and the interaction of each factor. 3rd party contributor
