501 Industrial Water Week 2026: Wastewater Thursday

A wastewater inspection appeared to expose a failed treatment program—until Trace checked where the sample had been collected. For Industrial Water Week 2026: Wastewater Thursday, Trace Blackmore, CWT, connects correct sampling, water reuse, and careful troubleshooting with the decisions water treaters make every day.

Check the sample location before drawing conclusions

In an early-career account, a plant operator faced a threatened shutdown after an inspector's sample produced out-of-spec results. Trace reviewed logs, spoke with the engineer, and tested two locations. The inspector had sampled before treatment rather than at the correct downstream location.

Trace then showed the customer both results and asked the inspector where he had sampled. That curious, factual approach corrected the misunderstanding without blame. The customer also recognized the need to escort unfamiliar inspectors so they could collect samples from the right place.

Recover water, nutrients, and energy

Returning guest Dr. Veronika Zhiteneva of Waterloop Solutions describes wastewater plants as future resource recovery plants, reclaiming water, nutrients, and energy. Kalpna Solanki, president and CEO of GAMECHANGERS Inc., shares reuse examples from British Columbia: treated effluent for snowmaking, biosolids composted with sawdust, and reclaimed water for toilet flushing and rooftop irrigation at the Vancouver Convention Center West.

Together, their greetings shift attention toward what treatment can recover and where reclaimed water can serve another purpose.

Investigate the disappearing hardness

In the fictional Detective H2O story, The Case of the Disappearing Act, an operator measures 2–3 ppm total hardness leaving a softener, yet the feedwater tests soft. After checking condensate return, repeating the analyses, and walking the process, the detective finds that the feedwater sample point sits downstream of EDTA injection.

The case explains how chelant can complex calcium and magnesium before the hardness test, leaving a blue indication even when hardness has passed the softener. The resolution is to investigate the softener's leakage and turn the operator's observations into training and procedures.

Share the work behind Wastewater Thursday

Trace invites listeners to photograph their favorite wastewater equipment safely, wear appropriate PPE, and share the photo with #IWW26. He also recommends Episode 444 for last year's Wastewater Thursday Detec
