The U.S. EPA gave Wisconsin some leeway last month on the question of phosphorus pollution from sewage plants in a decision that will affect wastewater treatment across the state.
Critics are concerned that an expected budget proposal from President Trump, if adopted, would gut programs designed to protect water sources from toxic algae.
Residents in Des Moines, IA, took issue with their water utilities at a public hearing at the capitol on March 6. The tension arose over a bill that would take apart the Des Moines Water Works board.
Current and former residents of Bucks and Montgomery Counties, PA, near Philadelphia, have joined together in a mass tort lawsuit against six manufacturers of firefighting foams dealing with personal injury claims.
In East Chicago, IN, rising levels of lead are becoming more of a concern to residents and both advocacy and environmental groups.
The U.S. EPA stepped in last month to treat radioactive wastewater at a shuttered factory in Mississippi.
Corrosion can be a huge problem that is potentially detrimental to your water system. Corrosion is not only a problem that can cause lasting damages on your water system, but it can also have harmful effects on the environment. The harmful effects of it to the environment lies mainly on the fact that a huge amount of water is wasted through the leaks that occur in so many areas of your water system due to corroded pipes.
McCrometer’s Full Profile Insertion (FPI) magnetic flow meter inserts into a pipe via a two-inch hot tap, avoiding the need to cut in a full bore mag. As Dan Hardin, Regional Sales Manager for McCrometer, explains in this Water Online Radio interview, it can then connect to any SCADA or radio system the utility might have to measure flow rate to within half a percent accuracy.
With modern combined cycle power/steam generation plants, the Heat Recovery Steam Generator (HRSG) is the major connection from the Combustion Turbine Generator (CTG) to the Steam Turbine Generator (STG).
Conversation at the 2016 SESWA Stormwater BMPs, LID and Green Infrastructure Seminar in Atlanta GA that I attended recently touched upon the idea of computers taking our jobs and ‘Engineering Bots’. This has of course happened in other industries, but I didn’t anticipate it happening in the stormwater planning, design and management world.
Those in the water industry know water is essential for life and brings economic value, but the economic role of water is often not as well understood by the general public. This paper reviews the history and development of our transportation, electrical, and energy infrastructure and then presents a plan for our nation’s water to be augmented from where we have it abundantly to where we badly need it.
As utilities update their metering to automatic meter reading (AMR) or advanced metering infrastructure (AMI) systems, integration with measurement devices in the distribution system has many benefits. McCrometer’s Dan Hardin recently sat down with Water Online Radio to discuss the flow measurement company’s Smart Output protocol that allows mag meters to connect to a water district’s AMI/AMR system.
Both rectangular and circular configurations have been commonly used in clarifier basins. The relative merits of the two have been discussed at length for decades. Historically, the selection of rectangular versus circular clarifiers has been based on past experience and the preference of the design engineer or design company.
This article is in support of the Imagine a Day Without Water campaign — a national online movement to raise awareness about the value of water and water infrastructure.
People concerned about their water footprint often make an effort to turn the faucet off quickly, take shorter showers, and cut back on watering the lawn.
The vast majority of chain and flight collectors in operation throughout the world do not have any form of monitoring system installed to protect against operational failure. Traditional safety devices consist of a shear pin sprocket device, with a limit switch, designed to protect the drive system if a load or torque exceeds the working load of the drive chain; in the event that this occurs, the shear pin will break, the limit switch will be activated, and the drive motor is shut down. This process will typically protect the drive chain and drive motor from failure. When the shear pin breaks, the clarifier is drained, the cause of the overload is established and corrected, a new shear pin is installed, and the collector is placed back in operation.
With Donald Trump appointee Scott Pruitt helming the U.S. EPA, the National Rural Water Association sees an opportunity to free its members from burdensome regulations and change the perception of the country’s smallest water utilities.
The U.S. EPA’s latest roster of concerning drinking water contaminants offers clues into what may be threatening consumers and the regulations that come next.
A U.S. EPA “call to action” for improving drinking water seems to lay the groundwork for the new president to address public health.
Polyfluoroalkyl and perfluoroalkyl substances like PFOA and PFOS have emerged as the contaminants of greatest concern for many consumers. While the U.S. EPA has issued a health advisory with limits on the chemicals, some affected communities wonder if their restrictions go far enough. So, what is an acceptable amount of PFOA in your drinking water?
With winter snow comes the inevitable introduction of a water source foe: road salt. With potential hazards posed to consumers and the environment, it’s up to treatment plants and utilities to do something about it.
Chemical, petrochemical, and oil-reﬁning plants are process-intensive operations with regulatory requirements to protect the surrounding water and air from the effects of industrial pollution. These external demands are matched by equally compelling internal pressures to address product puriﬁcation needs, ﬁnd alternatives to utilizing costly fresh water in production processes, reduce the carbon footprint, and operate efficiently and proﬁtably.
When is the last time you took a moment to stop, and smell your water? A continuous supply of clean and safe drinking water is something that most people take for granted. We rarely go to the tap doubting that the water will be clean and safe. Recently, the general population and water supply professionals have become concerned about the safety and protection of our drinking water supplies.
We all hope that the Flint Water Crisis – where cost-cutting measures led to the drinking water supply to become severely tainted with lead – was an isolated incident. However, it is not impossible that a similar event could happen again, especially in a similarly desperate city with limited financial resources. Here are a few key points that should be considered to avoid repeating such a tragedy.
For water treatment operators and utility officials, the summer months don’t just mean sunshine, pool parties, and barbecues. The season also brings the peak time for algal blooms, the toxic clouds formed in surface water thanks to increased nutrient contamination and rising temperatures. With rising instances of toxic algae around the country and increased regulations for eliminating it, utilities have had to keep pace.
The U.S. EPA’s Long Term 2 Enhanced Surface Water Treatment Rule (LT2) was adopted in 2006 to modify the Safe Drinking Water Act and more tightly control the spread of Cryptosporidium, a microorganism that can cause gastrointestinal infection if ingested. Since its inception, the rule has posed a treatment challenge to utilities that are susceptible to the tiny contaminant. But which utilities are at risk? And how should they approach treatment?
When Flint Michigan discontinued purchasing water from the Detroit Water Authority and began using the Flint River as their raw water source they unfortunately did not consider the potential impact on lead and copper corrosion and the impact on the public.
