The movie and sports term has infiltrated the business world and has important implications for the water/wastewater industry.
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.
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.
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.
In 2010, Shelby County Water Services (SCWS) was planning for the future. With new regulations on the horizon, SCWS determined that the Talladega/Shelby water treatment plant in Shelby County, AL, needed more effective removal of disinfection byproducts (DBPs). Specifically, the treatment plant needed help complying with the U.S. EPA’s new Stage 2 Disinfection Byproduct Rule (DBPR).
With the ongoing concern about water quality in Alaska, Philip Downing, the Remote Maintenance Worker for South East Alaska Regional Health Consortium, offered a new approach to a plant’s ability to continuously monitor and adjust treatment processes in response to changes in raw water quality.
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.
A municipal wastewater treatment plant investigated a sudden increase in fecal coliform exceedance events.
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.
The Signet 2750 and 2760 pH/ORP Sensor Electronics and Preamplifiers, featuring connectors, provide a variety of functions to suit various requirements
Hach, the leader in water quality, has developed a customized solution for water quality testing that takes the guesswork out of your measurements.
Purge and Trap Background
When using a concentrator system, it is not essential to understand how it works. However, a good grasp of the fundamentals helps you prevent problems and assists you when you are faced with tasks such as method development and troubleshooting. This section is not intended to be a full theoretical evaluation of purge and trap gas chromatography. The main purpose is to help you develop an understanding of how and why compounds are concentrated.
Teledyne Tekmar has been the market leader in environmental and drinking water testing for decades, having invented many of the instrumental technologies used in today’s lab. From TOC drinking water analysis to EPA compendium methods for air, soil and water, Tekmar has the right instrument for your application.
