Lead From Old Paint And Pipes Is Still A Harmful And Deadly Hazard In Millions Of U.S. Homes
The WHO estimates that more than 1 million deaths each year are attributable to lead poisoning. In more recent years, this number has risen at an incredible pace, with some research showing that nearly 5.5 million adults die from lead-related health complications. Understanding and addressing this persistent problem will require improved monitoring, targeted remediation, and a great deal more awareness and dialogue.

Quick Solutions To PFAS In Drinking Water, Especially For Smaller Systems
With funds falling short of costs for pending PFAS rules compliance, utilities require an economical treatment solution.

River Pollution Is Causing Harmful Outbreaks Of Sewage Fungus In The UK
The pollution of the UK’s waterways and coastlines with sewage is throwing its ecosystems out of balance. One well documented example is the spread of microscopic bacteria that can multiply rapidly into algal blooms, causing extensive dead zones once oxygen in the water has been used up. But there’s another pollution problem that has been largely overlooked, until now.

Arsenic In Landfills Is Still Leaching Into Groundwater Arsenic has long been considered "the king of poisons." Films such as "Arsenic and Old Lace" by Frank Capra and "The Name of the Rose" by Jean-Jacques Annaud illustrate the deadly effect that a high dose has on people. But when someone experiences arsenic poisoning, it's usually not the direct result of a diabolical plot — in fact, it usually isn't. So how do you figure out how the arsenic got into someone's bloodstream?

Mussel Fouling Prevention At Shepaug Hydroelectric Station
While the population of invasive mussels was very low along the Housatonic River in 2015, the population was expected to increase in the coming years. Firstlight Energy, a subsidiary of GDF Suez and operators of a number of hydroelectric facilities in Connecticut and Massachusetts, was concerned about the detrimental effect the anticipated increase would have on the cooling water systems of the Shepaug Hydroelectric Station.

Agriculture And Pharma Key To Solving Micropollutants
As the phrase "forever chemicals" enters the Oxford English Dictionary for the first time in 2024, and these fluorinated substances expand the list of micropollutants, it might be time for a change in the way these persistent environmental pollutants are tackled.

A Comparative Analysis Of UCMR 3 And UCMR 5 Of The Top U.S. Water Systems And Their Capital Improvement Projects For PFAS Remediation This article compares the PFAS contaminants present in the third and fifth cycles of the U.S. EPA's Unregulated Contaminant Monitoring Rule (UCMR) for some top water systems in the U.S., based on the population served, to examine the changes in their occurrence and levels over time. We will also discuss the projects by the water systems in their capital improvement plans for PFAS remediation in its water sources and to prevent further contamination.

Destroying PFAS In Wastewater To Help Safeguard Waterways Technologies for the destruction of per- and polyfluoroalkyl substances (PFAS) hold promise, but also face challenges.
VIEWS ON THE LATEST REGS
-
With the U.S. EPA’s recent announcement proposing maximum contaminant levels (MCLs) for certain PFAS, stakeholders throughout the water industry — representing utilities, industry, the environment, legal interests, and public health — were quick to offer their opinions.

A Q&A with human health toxicologist and environmental risk assessor Janet Anderson, Ph.D., DABT
-
The risk level linked to delivered drinking water from municipal utilities is very small, even if some high-profile examples of failure (see Flint, MI) have degraded public confidence to a degree. Our treatment professionals usually hit their targets, so the onus then shifts to the research and guidance that determines the safe level of various constituents through U.S. EPA protocols. But there is one contaminant that rulemaking hasn’t quite caught up to and which is downright deadly — Legionella pneumophila.

The Federal government plays a significant role in water project development, through both funding and regulating the industry. Water sector champion Mae Stevens shares how we as water professionals need to play an important role in influencing our congressional representatives and senators to win support of what we need to advance business opportunities.

With more than 50,000 community water systems (CWS) in the U.S., it is amazing that only 285 individuals had logged public comments on the U.S. EPA’s proposed Lead and Copper Rule (LCR) Revisions by the February 12, 2020 deadline. Yet, what those respondents had to say could have a big impact on how we deal with lead in drinking water moving forward. Here is a cross-section of the industry’s response.

The overall wastewater treatment process is complex, and each step is integral to ensuring water is properly purified. Effluent ends up in the plants, containing substances that must be removed before the water can be properly cleaned and returned for use. The range of potential contaminants is almost endless, and can include food, pulp, waste, or other substances. Afterwards, the water requires further scrubbing, with the aid of bacteria. It is in this part of the process that compressed air (ideally provided by energy-efficient rotary lobe blowers) plays a vital role.
