Japan plans to release radioactive water tainted by the crippled Fukushima Dai-Ichi nuclear plant into the Pacific Ocean.
Reliable and effective disinfection is a cornerstone of water and wastewater treatment, needed to protect public health. Most drinking water utilities are required to maintain a minimum disinfectant residual in the distribution system. This ensures adequate chemical was applied and remains in the system to kill pathogens. The most commonly used disinfectants — chlorine gas and bulk sodium hypochlorite — require operators to regularly handle these hazardous chemicals. Operators must be extensively trained in specialized procedures to ensure their safety and that of the community.
Most of the manufacturer’s representatives have just returned from attending WEFTEC 2018, held in New Orleans from September 30th through October 3rd.

As water utilities migrate toward remote system monitoring and real-time control, the risks associated with cybersecurity tick upward as well. While the rewards of digitalization offer real promise, the associated complexity and security concerns pose corresponding risks. That is why it is important to have an overall risk-management process for the organizational level, the business process level, and for the information system and data levels as well.
An infusion of $6 billion in federal funding for critical water infrastructure projects appears to be on the way to some very happy state and local officials. What a great gift!
In the world of water and wastewater, it's not enough to simply get a measurement back on how your system is performing. The non-linear process of water treatment and distribution requires ongoing adjustment and diagnostics based on process and regular instrument analysis. In this Water Online video, Tom Siller, Senior Director for Hach's Software Business Unit, discusses Claros, a new water intelligence system that not only analyzes but looks to fill the knowledge void as we face a generational change in our treatment operator ranks.
A suspended U.S. EPA official is calling out the Trump administration for what she sees as negligence on rules protecting children from lead.
As water and wastewater treatment plant (WTP/WWTP) processes and control systems become more sophisticated, maximizing operator effectiveness becomes more complex as well. A well-planned alarm and control strategy can make a significant difference between valuable decision-making information and confusing, disjointed, data points. This article highlights key strategies for foreseeing problems in advance, fixing them faster, and having a higher success rate by maximizing operator effectiveness.
Water and wastewater treatment applications encompass a wide range of processes, technologies, and physical/chemical methods. Among them, filtration and separation technologies are the core of treatment processes, and in many cases, they can be critical process bottlenecks. Engineering firms, engineering procurement and construction contractors, and end users have high expectations regarding a plant's operation, process design, efficiency, and performance.
There are a variety of costs that are easy to overlook in water treatment. But as Herman Coello, Products Manager for SIEMENS Process Instrumentation, explains in this Water Online video, accurately measuring your flow and treatment parameters can reduce them all. Much-overlooked expenses such as pumping inefficiencies and chemical overdosing can all be reduced to save operating expense.
In September of 2016, Ted Henifin took the first sip of water purified at a pilot treatment plant developed by HRSD (Hampton Roads Sanitation District). Now, the innovative water treatment program known as SWIFT — Sustainable Water Initiative for Tomorrow — is changing the lens through which communities and government officials view wastewater, drinking water, aquifer replenishment, and even fighting sea level rise.
The fate of a water utility in Indiana lies in the hands of a court.
In water plant operations, there’s no such thing as simply maintaining the status quo. Any utility that is not moving forward is falling behind. Whether a water treatment or wastewater treatment plant (WTP/WWTP) chooses to rely on in-house resources or outside specialists, here are some lifecycle management approaches they can use to upgrade control capabilities without compromising performance or return on investment.
Boiler feedwater is comprised of two very important, and increasingly expensive resources: steam condensate return and city (or well) makeup water. The condensate is valuable due to low electrical conductance, purity, and high temperature. The makeup water is valuable because it is being overused and under conserved in many parts of the country, making the cost of water rise in almost all parts of the U.S.
A Q&A with Berkeley Lab hydrological science expert Bhavna Arora, who explains how unseasonably warm weather and drought can affect water quality
The water utility in San Angelo, TX, is urging customers who paid their water bill online during the summer months to immediately get a new card.
While the laws of physics and chemistry have not changed, the ways that water and wastewater treatment plants (WTPs/WWTPs) are being forced to deal with them certainly have — e.g., disinfection byproducts (DBPs), tighter turbidity standards, harmful algal blooms, and PFAS challenges. Even when plant throughput stays the same, the demands on plant personnel continue to increase. Here’s how evolving toward better workforce management processes can help.
The City of Paramount conducted a pilot study for arsenic, manganese and iron treatment system at their Well 15 site. The onsite pilot test was designed to demonstrate the performance of the Loprest Water Treatment Company treatment process proposed for the new treatment plant.
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.
Prioritizing and funding pressing infrastructure needs can be challenging for water treatment and wastewater treatment plants (WTPs/WWTPs) of any size. The problems are particularly stressful for smaller utilities where a thin layer of upper management staff wears an inordinate number of hats. The good news is that funding assistance does exist — if you know where to look for it and take the right steps to apply for it.

The objective of the pilot study was to demonstrate “proof of concept” if coagulation followed by filtration was a viable technology to remove arsenic in water from Well No. 6 when raw water arsenic levels are so high, >70 ppb. Preparations were made to reduce the pH of the raw water if it was required. Also, two unique arsenic adsorptive medias were evaluated as a final polishing step to the effluent of the coagulation/filtration process.
