41. 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.

42. 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.

43. 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.

44. Identifying The Best Lead Sampling Techniques To Protect Public Health 10/23/2018

    If lead is found in drinking water, it is important to identify where it is coming from within the water system — that means taking samples at every stage, from the distribution system all the way to the plumbing system inside the home, also known as premise plumbing.

45. Coping With Mixed-Source Water Quality And Corrosion Challenges 10/12/2018

    When it becomes necessary to expand or blend water supply sources, variety is not necessarily the spice of life. Whether new water sources are surface water or groundwater, fresh, brackish, seawater, or water recovered from aquifer storage, they can ultimately impact water treatment plant (WTP) operations and finished water quality — including compliance with the U.S. EPA Lead and Copper Rule.

46. 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.

47. 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.

48. Pride And Prejudice: A Philadelphia (Water Department) Story 7/12/2018

    Recently, I had the opportunity to tour a unique and innovative facility, the Bureau of Lab Services (BLS), the “water quality heartbeat of the Philadelphia Water Department” (PWD), as described by BLS director Gary Burlingame.

49. The Importance Of Robust Water Management: The Evolving Challenge Of Safeguarding Global Waterways 7/12/2018

    As manufacturing across the world further develops, new chemicals and contaminant threats are being introduced into the environment, creating new challenges for industrial and municipal treatment operations.

50. FMCW Or ToF? Which Radar Level Technology Is Best For Tank Gauging In Custody Transfer Applications? 4/9/2018

    Measuring the level of tanks used to hold fluids for custody transfer can be expensive. This is not due to the cost of the measurement instrumentation, but to what inaccurate measurements can cost the company. Picking the right instrumentation for applications is important. Which radar level technology should you choose for tank gauging in custody transfer applications? Frequency Modulated Continuous Waveform (FMCW) or pulsed Time-of-Flight (ToF or PToF).
