41. Calibrating Success: Improved Tools To Maintain Flowmeter Accuracy 7/10/2019

    Water utilities with highly successful monitoring programs tend to share a common trait: they have a well-defined plan for calibration that emphasizes frequency and tracking. However, when done properly, this process is time-consuming and often leads to unnecessary labor and downtime. The good news is that advanced metering technology is available for plants to get a better handle on the instrument’s performance with significantly less effort.

42. Water Monitoring's Triple Threat: Bad Habits, Bad Readings, Bad Results 7/8/2019

    When water and wastewater plant operators can’t get accurate flow measurements or analytical readings — or lack confidence in their instruments’ readings — it creates challenges with the process. When substandard water goes to homes and causes a boil order, or discharge pollutes a lake or reservoir, the resulting bad press, fines, and potential lawsuits erode public confidence. Avoiding these kinds of problems is rooted in good preventive maintenance habits.

43. Sounding The Alarm On Silent Noncompliance 7/5/2019

    Water and wastewater utility operators work diligently to operate within strict guidelines, ensuring their facilities are producing the best drinking water and highest quality effluent possible. Despite all their efforts, however, it can be easy to fall outside of regulatory compliance without even being aware. The key to avoiding problems like these is to understand how silent noncompliance can happen and knowing when to raise a red flag.

44. The Great Flood And Future Predictions 3/27/2019

    Did you know that the earliest recorded flood is that of the Great Flood detailed in Christian Bibles, the Torah, and the Quran? I was, therefore, amused to hear from a channel partner about a flow monitoring job in the Eastern Anatolia region of Turkey, at the foot of Mount Ararat. Why? Because Mount Ararat is cited as the place where Noah’s Ark came to rest after the Great Flood (Genesis 8:4).

45. Rapid Microbial Assessment Following A Case Of Legionellosis 12/3/2018

    A case of legionellosis — an illness acquired from Legionella bacteria, which can grow in cooling water and potable water systems — was diagnosed at a medical retirement home.

46. Troubleshooting A Sudden Fecal Coliform Non-Compliance Event 11/26/2018

    A municipal wastewater treatment plant investigated a sudden increase in fecal coliform exceedance events.

47. What Can 2^nd Generation ATP Do For An Operator Or Field Technician? 11/1/2018

    It’s important to start with the fact that this is not a regulatory test. This technology won’t replace any required compliance tests and the results are not reportable, which is actually a great benefit to our users. While regulatory testing is important, compliant does not necessarily mean clean.

48. How To Mitigate Biofouling In Your Industrial Process Using 2^nd Generation ATP 10/9/2018

    Microorganisms can wreak havoc in industrial processes in a number of ways – from slime formation that causes paper breaks and excessive downtime in papermaking facilities, to costly recalls of spoiled final product. Consequently, an effective microbiological control program, which includes accurate and reliable monitoring, is critical for maintaining an efficient process and final product quality.

49. Water 4.0 And The Wastewater Cycle 9/4/2018

    While it may be premature to claim wastewater management’s arrival in the digital age, we can herald the eventuality, chart the progress, and examine potential implications.

50. EPA's ENTACT Study Breaks New Ground With Non-Targeted Research 8/1/2018

    EPA scientists are leading a multi-phase project to evaluate the ability of non-targeted analysis laboratory methods to consistently and correctly identify unknown chemicals in samples. EPA’s Non-Targeted Analysis Collaborative Trial (ENTACT) was formed in late 2015 and includes nearly 30 academic, government, and industry groups. Non-targeted analysis involves analyzing water, soil and other types of samples to identify unknown chemicals that may be present, without having a preconceived idea of what chemicals may be in the samples.
