We know many college campuses are testing students but one school is taking things to another level.
To help keep its staff and students safe, Ringling College in Florida is testing dorm wastewater for COVID-19.
A sample is collected and then sent for testing, with results available within a couple of days.
The idea is to catch the virus early - before students even show symptoms.
Ringling says testing dorm wastewater allows them to get ahead of a potential outbreak.
So far all tests have been negative. If there is a positive sample then school officials say everyone in that dorm will be tested.
