Employee Indicted for Illegally Accessing Water Treatment Network
|
A Tracy man has been indicted for allegedly accessing the computer network of the Discovery Bay Water Treatment Facility and shutting it down, the U.S. Department of Justice said Thursday. Rambler Gallo, 53, is accused of intentionally causing damage to a protected computer at the facility located in the town of Discovery Bay and intentionally uninstalling the main operational and monitoring system for the water treatment plant. He then allegedly turned off the servers running those systems, prosecutors said.

Fluorinated Carbons, PFAs, Found in Nearly Half of Us Tap Water
|
The results of a new study released last week by the US Geological Survey (USGS), a bureau of the US Department of the Interior, found that nearly half of all US tap water contain industry-made perfluoroalkyl and polyfluoroalkyl substances (PFAS), referred to as “forever chemicals” due to their stable molecular structures that make them highly persistent in the environment. Some PFAS may take over 1,000 years to degrade, if at all.

More Data for State’s First Membrane Bioreactor Wastewater Treatment Plant
|
Using Ignition, H2O Innovation and Automation Station upgraded the existing indicator light board and push button panels to a full state-of-the-art SCADA application. The team added local control to multiple automation systems, real-time trending, reporting, and a data historian. The SCADA system is now being used by the City of Decatur’s Mayor, the Director of Public Works, and neighboring cities’ Utilities Directors — allowing them to make real-time decisions for their respective departments.

New Jersey Utilities Float Solar Panels on Reservoir, Powering Water Treatment Plant
|
New Jersey’s Canoe Brook Water Treatment plant produces 14 million gallons of drinking water a day. Each one of those gallons weighs around 8 pounds, so it’s quickly apparent that a large amount of energy is needed to move water from a reservoir to the treatment plant and into the 84,000 homes and businesses that the New Jersey American Water Company serves in the area.

Some Cities Are Leaving Lead Pipe in the Ground
|
Prandy Tavarez and his wife were expecting a baby when they bought a four-bedroom house in a well-kept neighborhood of century-old homes here. They got to work making it theirs, ripping off wallpaper, upgrading the electrical and replacing windows coated in paint that contained lead, a potent neurotoxin that can damage brain development in children.

Step-Feeding Food Waste Fermentation Liquid as Supplementary Carbon Source for Low C/N Municipal Wastewater Treatment
|
Municipal wastewater treatment often lacks carbon source, while carbon-rich organics in food waste are deficiently utilized. In this study, the food waste fermentation liquid (FWFL) was step-fed into a bench-scale step-feed three-stage anoxic/aerobic system (SFTS-A/O), to investigate its performance in nutrients removal and the response of microbial community as a supplementary carbon source. The results showed that the total nitrogen (TN) removal rate increased by 21.8-109.3% after step-feeding FWFL. However, the biomass of the SFTS-A/O system was increased by 14.6% and 11.9% in the two phases of the experiment, respectively.
