Science Buddies: "Ask an Expert"

I am doing independent bio aquatic research on my college campus. Two of the three ponds that I tested came out with pH of 3 and 4-- acidity that matches that of acid rain. This is extremely unusual, so I redid the pH test and came up with the same results. Can a science professional or grad student explain to me what could cause the pH levels to be so acidic?? I know that heavy metals, pollution, runoff can impact acidity. However, my college campus is fairly green (sustainability wise). Another thought that I had was the amount of organic decay near the bodies of water, but I'm not sure if that could cause such acidic pH. Please help!!

Hi dianagodlevskaya,

These forums for specifically for K-12 students, parents, and teachers working on science fair projects. Because your questions don't relate to that type of project, a different set of online forums will be better able to help you. If you are in the U.S., then you might also consider running your questions past someone at your local USDA Extension office. An internet search for "(name of state) extension service" should get you headed in the right direction.
