G.R.I.D. Checklist for students

Only complete items listed on YOUR checklist

Part 1:
Collect Water Sample

Use the water sample kit (Resealable bag with clear, sample cup, lid, and dropper) to collect a sample from any trapped water you might find. You must do this BEFORE you dump out any water you find. Didn’t find water? You don’t need to submit a sample but remember to submit the unused kit!

Clear the area around your home

Tip out any trapped water remaining in containers onto the ground


Toss out any unused containers that might trap and hold water (even if they are currently dry). Ask for help from a family member if you can’t get rid of the water by yourself!
