Researchers from Virginia Tech were knocking on doors throughout the city of Flint.

This time their focus was around hot water heaters and what could be lurking inside.

Many residents believe lead and other heavy materials leaching from corroded pipes have built up in their water heaters and could be making bath time potentially dangerous.

The researchers are testing not only for lead, but also for bacteria including Legionella.

Taylor Brady, graduate assistant at Virginia Tech, is one of seven students doing evaluations for Professor Marc Edwards. They are testing the water quality in some 30 homes in Flint over the next few days.

"So we were expecting it to be really bad. We were expecting to find water heater that where really clogged up and you know having a lot of sediments, but we have not found them," Brady said.

Gov. Rick Snyder said positive results are taking place with the Flint water.

"We've seen significant improvements from months ago. The flushing program appears to be having a very positive impact so that's been very helpful in this process," Snyder said.

Although initially Flint may be looking good, researchers are concerned about the potential Legionella contamination, which is more potent during the hot summer months.

Although questions remain regarding the severity of the contaminated water, the researchers know the work they are doing could save lives.

"It's literally beyond description. It's a life changing event. Since last June our team has been working. All this is beyond my imagination for what I can do for a grass root efforts," said Joyce Zhu, Virginia Tech researcher.
