Water Quality Testing First Wave

On Thursday, May 12, approximately 50 students from the Hanover Middle School joined naturalists and volunteers from the South Shore Natural Science Center for their initial foray into the world of water quality testing. The sixth and seventh graders broke into five separate groups and headed to five separate sites along Third Herring Brook in Hanover. At each site the kids took different measurements – on turbidity, conductivity, salinity, ph, and dissolved oxygen – before focusing on macroinvertebrate sampling.

Speaking of which, they found lots of it: scuds, dragon fly larvae, mayfly nymphs, orb snails, fingernail clams, predacious diving beetles, crayfish, toad and bullfrog tadpoles and even river herring. The students then returned to school, knowing they had data to crunch and a final report to deliver together.

After this spring’s students are done, students from the Germantown Neighborhood Center in Quincy will take up the study in the summer before a new, third wave of Hanover Middle School students will repeat the studies in the fall. The entire program, a partnership between Battelle, the South Shore YMCA and the North and South Rivers Watershed Association, is introducing approximately 150 students to the concept of citizen science, and the idea that their data is just as valuable as anybody  else’s!
