Who keeps your tap water safe to drink?

DAYTON, Ohio (WDTN) – Pouring a glass of water seems simple, but you’d be amazed at what goes into making sure your tap water is safe.

The water treatment plant services 400,000 people in Montgomery and Greene counties.  Scientists test the water before it even gets into the plant, then again before it heads out of the plant to make sure the process is working correctly.

Filling a glass of water is easy, but before the water reaches your tap, it first has to go through the water treatment plant in Dayton, but before the ground water is even pumped into the plant, the surrounding well fields are tested for contaminates.

“What we do on this instrument is check for VOC’s or volatile organic compounds.  They’re usually from industrial waste old landfills,” said Julie Wiles, chemist.

Once the water is pumped into the plant, minerals are removed and others are added. so it’s clean and clear out of your tap.

Keshia Kinney Water Treatment Tech Supervisor says, “We soften the water then we filter it once we’re filtering we’re checking for turbidity that we’ve removed, chlorinating the water for proper disinfection and we also add fluoride.”

Tim Truman is a research and control specialist. He’s checking the water leaving the plant to make sure the treatment process is working correctly.

The different colors show how much calcium and magnesium is in the water.

“In our process at the plant, we probably remove about half of the mineral content because our water in this area is rather hard,” Truman says.

The final tests are taken outside of the facility.

These are just some of the water samples from the city of Dayton. The water lab tests about 40 samples per week to test for bacteria like E.coli. Here are some of the results.

The glowing jar on the right is an E.coli control, the clear jar on the left is a good control and the jar in the middle is a water sample. You can see it’s clear just like the good control.

All of these tests to make sure the water you drink is safe and healthy.
