Chemical engineer Dave Tracy provides insights into this common question, and provides resources on how to build a testing routine that works for you.
New details about SARS-CoV-2, the virus that causes COVID-19, seem to emerge daily. Expanded Testing Requirements A concerning but important finding is that viable virus can be recovered from pre-symptomatic individuals several days before symptoms appear – as well as from asymptomatic individuals. This highlights the need for effective surveillance and contact tracing programs, which include identifying and testing asymptomatic and pre-symptomatic individuals, to prevent further spread. While contact tracing will always require clinical testing for… Read More
Water conservation will be among the most critical issues that mankind faces in the future, and nowhere has this been clearer than Cape Town, South Africa.
Water resource recovery facilities (WRRFs) are among the most common pieces of municipal infrastructure. It’s accepted practice for communities of all sizes to treat wastewater in some way before returning it to the environment. As the worldwide focus on issues like water quality and waterborne diseases has increased, so has the attention being paid to… Read More
Using a highly unique solution to a common and sometimes vexing problem, a cocker spaniel and a springer spaniel in Britain are finding leaks in drinking water pipes by using their sensitive noses to sniff out the chlorine in the water. Snipe, a two-year-old cocker spaniel, received months of training from his handlers, who… Read More
At this time of year, ‘Year in Review’ lists seem to be everywhere and the water industry is no different. 2018 brought some exciting changes for us at LuminUltra, so here’s a look back at some of the events we’re particularly proud of as a company and some of the stories that made us… Read More
Whether I’m talking to attendees or customers in our booth at WEFTEC, or attending presentations, I always walk away with valuable information. That is the key, as you’ll see in my #1 take-away from WEFTEC. 1. Data ≠ Information I initially heard this statement during Dr. Mark van Loosdrecht’s presentation on wastewater microbial… Read More
Metagenomics through the incorporation of next generation sequencing (NGS) is changing the way wastewater treatment plants are monitored and understood. NGS can be used in aerobic and anaerobic systems to monitor for problematic organisms, such as filamentous and foaming bacteria, and beneficial organisms, such as ammonia-oxidizing bacteria and methanogens. NGS is also allowing old… Read More
From the editor: This is the thirteenth post in an ongoing series profiling microorganisms of particular significance in water and wastewater systems. In this series we will cover microorganisms of many types including some that are beneficial, inhibitory and pathogenic. Methanogens are a group of microbes that produce methane gas through the breakdown of… Read More
If you find it easiest to understand a new concept through some type of visualization, you’re not alone. If you happen to be a ‘visual’ person and have an interest in water, there are a ton of great resources available online that can bring out the map-geek and marine biologist in anyone. Here at… Read More
