Imagine A Day Without Water-Researchers and Utilities Collaborating to Improve Quality of Drinking Water
By Linda Nogueras
Do you ever think about our water beyond the instance that you consume it? Imagine you had the chance to visit a water treatment plant and witness a researcher getting water samples to provide insight into technologies that could significantly raise the safety of drinking water. I had the opportunity to join Ohio State graduate student Judith Straathof as she went on her weekly collection of water samples at the City of Columbus Dublin Road Water Plant. I only needed to listen to her talk about the project for a couple of minutes to feel as much passion for it as she did.
The day started with a short drive from the Ohio State campus to the treatment plant, where we were welcomed by a team of operators who monitor the quality of the water, the safety and state of the tanks, and the efficiency of the water treatment processes. Judith first collected a sample of water, which enters the treatment plant from source water. The other water samples have to be collected from the midst of treatment, in the coagulation and softening reactors (Photo 1). From farther away, these reactors just looked like big rectangular pools and I tried to guess how deep they were. Luckily, one of the tanks was undergoing maintenance and was drained and I could clearly see the tank’s depth and the huge volume these tanks usually hold. We walked towards the end of the operating tanks, where Judith usually collects water samples for her experiments. These tanks contain large amounts of constantly mixed particles, but according to the operator joining us, occasionally fish can make it to the tanks and the operators have to help them get out.
The visit took about 20 minutes, but this was only the beginning of Judith’s work for the week. We walked back to Judith’s car, with a cooler full of water samples, and drove back to the OSU campus so Judith could start her sample analyses and experiments. First, Judith helped me get safety glasses on top of my own glasses and explained to me the rules of the lab: no drinks, no food, wear your safety glasses and lab coats as you work with the samples. Then we could start
As we celebrate this year’s Imagine a Day without Water, keep in mind that water treatment processes occur every day with the goal of maintaining a water quality that will keep the public safe. According to the Ohio EPA, there are around 4,800 public water systems in Ohio that serve approximately 11 million people daily.
