Here 6th grader Talinn H. reflects on his experience helping to monitor the water quality of San Francisquito Creek.
All life on earth needs water to survive. If our water sources become dirty, humans, animals, and plants will be in danger. How did I learn about this? My mom found an organisation called Grassroots Ecology, that organizes programs that teach volunteers how to make their local environments cleaner. I chose to participate in a 3 hour program that measures water quality. My parents and I went to four different sites along the San Francisquito Creek for this project.
To measure turbidity, we lowered a metal cup attached to a long string into the creek. When it was filled, we pulled it up, and put the water into a little vial, shook it, and poured it back out. We repeated this three times to make sure the vial was clean and left the water inside the fourth time. Next, we put the vial into a machine called a turbidimeter, which measures the clarity of the water. The range is from zero to one thousand, zero being the cleanest. At the first site, we got 2.19! That was very surprising to me since I thought creek water would have been dirtier. We did this procedure twice at every site to make sure the results were correct.
For the second activity, we used another machine to measure the acidity, temperature, and dissolved oxygen. We lowered a cord connected to the machine into the water, and noted down the results in a form that the guide gave us. For animals to drink water from the creek, the pH has to be between six and nine. For the sites that we went to, the pH was always between eight and nine which is very good.
During this activity, I think I showed the principles of awareness and responsibility. If our community doesn't even realize how and why the water is getting polluted, then there is no way to solve the problem. Once we realize what the cause is, we will be responsible pick up trash and pet waste, not used pesticides, not wash cars in driveways, not let car oil get to the creek, etc...If we don’t do this, it will impact the vegetation, and animals around the creeks, so it’s very important that we do.
I didn’t really sacrifice anything. It was on a Saturday morning but it wasn’t too early so I wouldn’t say I lost sleep. Also, it was really fun, interactive and I learned a lot. It was an opportunity for me to try something new.
In conclusion, I think this service learning project was a very good way to learn something new, and help nature. More people in our community should do activities like this too, so they can start being aware of the problem and help fix it. I definitely would go back and do a another activity with this organization in the future. Now I understand why it was so important to restore the San Francisquito creek near INTL on Bayshore road, even though there was really bad traffic to school last year.
