The Devastating Legacy Of Algaecides: Why The Quick Fix Is Failing Our Lakes
As warmer months approach, water management professionals must confront the compounding consequences of biocidal algae treatments.
What Is The Future Of Source Water Protection? Water utility managers and municipal leaders have long struggled amid the convergence of several threats to public water supplies. During a recent Water Online Live event, I sat with a panel of industry experts to examine the transition from reactive crisis management to a proactive, adaptive resilience framework.
Drinking Water Contaminated With 'Forever Chemicals' During Pregnancy Linked To An Increased Risk Of Childhood Asthma
While most of us are routinely exposed to low levels of PFAS, some communities are exposed to far higher levels from nearby pollution sources. A new study shows that in one of these at-risk communities, children were more likely to develop asthma if their mothers were exposed to very high PFAS levels during pregnancy.
The Pragmatic Shift In Source Water Protection: Moving From Symptom Management To Root-Cause Accountability A shift in how we approach source water protection is long overdue. Currently, we are trapped in a cycle of escalating costs, forced to treat symptoms like algae and invasive weeds expediently with chemicals while the underlying risk in the reservoir compounds. True risk management requires breaking this cycle.
The AWWA Said $2.4 Trillion. It Missed The Compound Interest. Einstein once said of compound interest, "He who understands it, earns it. He who doesn't, pays it." The same logic of compounding applies to the organic sediment accumulating on the floor of your drinking water reservoir. The longer you wait to address it, the more exponentially expensive it becomes to fix.
Designing Resilient PFAS Treatment Strategies For Water Agencies Water agencies across the U.S. are facing a rapidly evolving regulatory landscape for per- and polyfluoroalkyl substances (PFAS) that poses a conundrum: Should they take a cautious or aggressive approach to treating PFAS contamination in their water system?
The Future Of In Situ Chemical Oxidation For Targeted Solvent Destruction
The U.S. EPA’s 2026 trichloroethylene (TCE) compliance deadlines are now forcing a concrete shift toward source-zone destruction. In situ chemical oxidation (ISCO), sequenced with enhanced bioremediation, is proving to be the most credible path to groundwater contaminant rebound mitigation.
When Drinking Water Raises Bigger Questions About Brain Health And Environmental Risk
A new study linking certain groundwater sources to higher Parkinson’s risk underscores a broader question for the water sector: how environmental exposures in drinking water may influence long-term health.
EPA Seeks Court‑Ordered Removal Of 4 PFAS Limits The U.S. EPA is testing a new procedural strategy to remove four PFAS drinking‑water limits from ongoing litigation, asking the D.C. Circuit Court of Appeals to invalidate those limits on the grounds that the EPA itself committed a procedural misstep when issuing the 2024 PFAS rule.
Putting The National Toxicology Program's Fluoride Review In Context Despite renewed public concern over fluoride and cognition, the National Toxicology Program’s findings focus on high‑fluoride groundwater conditions — not the controlled levels used in U.S. drinking water systems. Understanding that distinction is critical for utilities navigating policy questions and community expectations.

PFAS Reference Materials

Per- and polyfluoroalkyl substances (PFAS) are man-made chemicals that have been used in industry and consumer products worldwide since the 1950s.
PFAS can be found in:

Convertible-Potable-Water-Treatment-System-1

Convertible Potable Water Treatment System: PWT-12/50

For remote sites of 35 to 200 people, the newterra PWT-12/50 offers optimal flexibility – adapting to changing camp populations quickly and easily. The base 40' unit is a fully self-contained potable water treatment plant with capacity for up to 50 people.

NeoTech D228™

The NeoTech D228™ is specially designed to disinfect water and is an essential component in advanced oxidation processes.

Potable Water Treatment Mini Train System_Datasheets_PWT-125_

Potable Water Treatment Mini Train System: PWT 125

For remote sites with peak populations between 500 and 2,000 people, the newterra PWT-125 Mini Train System offers exceptional capacity and flexibility. The base system for up to 500 people consists of two 40' containerized elements – a discrete distribution/disinfection unit and a treatment unit. The Mini Train design allows up to four (4) treatment units to be added to a single distribution unit, providing potable water treatment for 2,000 people. The system is designed to integrate with containerized or free standing tanks for water storage. The treatment system is available for both groundwater and surface water sources.

Aqueous Electrostatic Concentrator

The Aqueous Electrostatic Concentrator's (AEC) modular design provides a small footprint and low energy consumption, and it can be skidded, trailer-mounted, or custom configured to fit into existing spaces.

A New Way Of Designing With Reverse Osmosis Membranes

Process design in water treatment is historically confined to proprietary or user-defined spreadsheets on a unit operation basis, with users manually adding results from each unit process upstream into the next operation.
