The state Environmental Protection Agency says all the most recent water samples in a northeast Ohio village are below the federal standard for lead.
The state EPA says 15 new samples tested below the threshold.
Ohio EPA officials say nearly 900 samples have been submitted by homeowners in the village of Sebring in Mahoning County over the past three weeks.
A total of 55 homes have shown lead levels above the federal standard since the middle of January.
The EPA says running the tap for a few minutes eliminates any detectable lead in the water.
Sebring has come under scrutiny after state environmental officials said the operator of the village water plant waited months to notify people about high levels of lead coming from their pipes.
