Raquel Crandall, left, and Theresa Howick, both of Celina, get ready to perform water quality tests on water from Grand Lake on Tuesday at the Harbor Point 4-H Camp. The two are qualified data collectors certified through Ohio EPA who work as volunteer water quality monitors gathering data for the Grand Lake/Wabash Watershed Alliance. The two were practicing chemical tests to make sure they had all steps down, said watershed coordinator Laura Walker.
