On Monday, we again visited McCurdy High School to discuss water quality with Ms. Pepersack’s Biology class. We compared the Santa Cruz River and the McCurdy Acequia using our Vernier probes and the LaMotte kits. Again, we got very interesting results.



Why are the pH and conductivity values for this ditch so high? One important fact is that the ditch is no longer running, so this water has been sitting for a while. Perhaps salt from the sidewalks runs off into this water? This is our current working theory- let us know if you have any ideas!
Happy Thanksgiving!
