A criminal investigation into the Flint, MI, water crisis has led state officials to seek federal charges against two former state-appointed emergency managers, accusing them of having a focus on saving money instead of the safety of residents.
In a surprising twist, a former supervisor with the Ohio Environmental Protection Agency, who appealed her firing over the handling of lead in Mahoning County community's drinking water, has been rehired for a new job within the agency.
President-elect Donald Trump has selected Oklahoma Attorney General Scott Pruitt to lead the U.S. EPA, the federal agency with jurisdiction over water and wastewater regulations.
Arizona regulators kept a close watch on Johnson Utilities this week after samples showed that high nitrate levels had rendered tap water unsafe for infants.
For some time now Portland has had problems with lead in its drinking water. As in many cities around the country, lead contamination there can be attributed to problems with aging pipes and a lack of testing.
Flint, MI, has a bad track record for changing water sources. When the city switched sources two years ago in an attempt to cut costs, it underwent a major water-contamination crisis.
Operating a wastewater facility is no easy task in today’s world. There are many challenges that owners / operators face, including sewage composition, water consumption, and an aging infrastructure.
While most of the country was seeing red, white, and blue this past Fourth of July, many Florida residents were seeing green.
As part of its Long Term Control Plan to reduce combined sewer overflows (CSOs) to the Merrimack River, the City of Nashua, NH constructed a new Screening and Disinfection facility (SDF) to reduce untreated discharges of CSOs to the Merrimack River.
Oleon NV is one of the leading producers of oleochemicals since the 1950s and specializes in converting natural fats and oils into a wide range of oleochemical products, such as fatty acids, glycerine, esters, dimers, technical oils, specialty oleochemicals and biodiesel. All the products, made from renewable raw materials, combine high performance with ready biodegradability
Anshan Steel, one of China’s largest steel producers, required demineralized water for its boiler application as the plant planned to expand its capacity.
Collectively in the municipal wastewater treatment industry there exists a tremendous knowledge base. Among those who are actively engaging in the trade, a resource of innovative skill sets is potentially accessible through many of the individuals’ experiences and discoveries. The challenge is: How can these people work together effectively to benefit from this state-of-the-art resource?
Radar technology is often viewed as the “best” method of level measurement, but this isn’t necessarily true in the water industry.
When machine builders partner with subsystem specialists to simplify and streamline their equipment design, engineering, production, and support, they can save large amounts of time and, in many cases, up to 50 percent of costs — helping to boost profitability and customer satisfaction.
The Rueter-Hess Water Purification Facility, located in Parker, CO, southeast of Denver, serves a community of approximately 50,000 residents. Faced with rapidly declining groundwater sources, the 10-MGD facility (expandable to 40-MGD) was opened in 2015 to process a renewable water supply for the Parker Water and Sanitation District (PWSD).
Advanced Metering Infrastructure (AMI) has been available for some time, but the majority of water utilities still don’t utilize it. There are varying obstacles that keep more from embracing the technology, from cost prohibitions to lack of expertise. Increasingly, ways around these obstacles are emerging.
A known carcinogen that makes its way into drinking water supplies through personal care products is under fire in New York. While the state mulls stricter limits, consumers remain exposed.
In the years the U.S. EPA has worked under the Obama administration, the agency has been very active. Depending on your perspective, that may be good or bad. While some see new regulations as necessary to protect citizens and the environment (and to drive innovation in the water sector), others argue that recent actions have been overly restrictive and unduly burdensome.
The U.S. EPA is considering tightening its water regulations on atrazine, an herbicide known to cause adverse health effects if ingested. As researchers and state regulators advocate for stricter limits, it may be time to act.
The federal Drinking Water State Revolving Fund was designed to help communities pay for infrastructure projects and meet safety regulations. But can it be applied for the greatest threat to drinking water of our time?
As the U.S. EPA’s Lead and Copper Rule turns 25 years old, the country has become inundated with contamination crises. A much-needed update to the regulation may put an end to that.
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?
There have been many publications lately that claim universal appeal of the ORP sensors and their applicability across the board. This concerns me, because the authors sometimes forget to mention some well-known practical limitations of the method, let alone the realities of water treatment applications potentially influencing the sensor performance.
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.
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.
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.
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.
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.
