Emergency management officials will collect water samples to test for E.coli on Monday in the immediate neighborhood where a sinkhole swallowed two homes in Florida.
Additional residents in the area — where many people use wells — can have their water tested for a fee.
Pasco County officials said in a news release that families from four of the homes that were initially evacuated were allowed to return Saturday evening. Five other homes are still deemed unsafe for occupancy.
The sinkhole opened up Friday morning and grew to 225 in diameter and 50 feet deep, taking with it the two homes and a boat. No one was injured.
The scene is being considered a hazardous materials incident because of possible septic tank issues and building debris.
