A follow-up test on the water at Plum Point Middle School came back negative, announced the school’s principal Zach Seawell via email on Wednesday.

A routine test last week showed the presence of total coliform bacteria, described by the Calvert County Health Department and Calvert County Public Schools as not being harmful itself but an indicator of something more serious. The water was treated with a chlorine substance and the follow-up test was conducted Monday afternoon.

After last week’s test came back positive, Plum Point Middle School had set up water stations and supplied hand sanitizer. Seawell’s email on Wednesday stated that with the negative results on Monday’s test, the water stations were taken down and the water fountains were reopened.

“The students handled the situation very appropriately and maturely without any incidents,” Seawell said.
