Jumping into the waters of Ulatis Creek Monday, 18-year-old Vacaville High School senior Spencer Pihl remarked how cold his feet were getting.
But Pihl wasn’t complaining. It was all for science.
Pihl and about 90 of his fellow classmates in Erin Gordon’s Advanced Placement Biology classes at Vaca High were taking part in the 11th annual Solano County Biomonitoring Program, a hands-on science program run by the Solano Resource Conservation District.
