The Center for Neighborhood Technology (CNT) is initiating a collaborative campaign to “Fix the Leaks” in the Great Lakes states. We are calling on state and municipal leaders, water service utilities, industry-related agencies, and Great Lakes institutions to work together on:
- New research regarding water loss and related issues
- Education and technical support opportunities to encourage industry best practices
- Investigating and shaping supportive policies that encourage best practices, public reporting, and improved planning.

The Case for Fixing the Leaks: Protecting People and Saving Water While Supporting Economic Growth in the Great Lakes Region

Go to your local supermarket fish counter and you are likely to be faced with a mouth-watering choice: salmon, bream, prawns, lobster, mussels and oysters. All sustainably farmed and far cheaper than their wild counterparts, making fish affordable for most and something we can eat with a guilt-free conscience. But are those rope-grown mussels, or the succulent farmed salmon steaks really as environmentally benign as we are led to believe? A new study shows that the proliferation of marine farms is adding bucket loads of excess nutrients to our oceans, potentially triggering harmful algal blooms.

Water recycling, also known as reuse or reclamation, is not new; nonpotable (not for drinking) water recycling systems have been in place for decades. In arid states, including Texas and Nevada, and rainy states, such as Florida and Virginia, municipal wastewater is collected and treated to an extent that doesn’t meet drinking water standards, but is approved for certain uses that don’t involve human contact, such as agriculture, landscaping and golf course irrigation.
Today, due mainly to increasing drought conditions and groundwater depletion, nonpotable uses are expanding. Municipalities are figuring out more ways to treat sewage less like waste and more like a resource. In addition to watering golf greens, recycled water is being used for street cleaning, fire-fighting, geothermal energy production, preventing seawater intrusion into freshwater aquifers, industrial processing, commercial laundering, restoring natural wetlands and creating constructed wetlands.

The majority of discharged municipal wastewater nitrogen contains dissolved organic nitrogen (DON), and increasing attention is now being paid to characterizing the concentration, structure and properties of DON and understanding how it is transformed across activated sludge processes. For instance, where is DON removed or produced during biological nitrogen removal? What is the effect of biological nitrogen removal on DON? Information on how DON behaves during biological nitrogen removal in wastewater treatment plants is very important for understanding the role of treatment units in removing it. However, our knowledge of the characteristics of DON in biological nitrogen removal wastewater treatment plants is still very limited.

Only about half of the prescription drugs and other newly emerging contaminants in sewage are removed by treatment plants.
That’s the finding of a new report by the International Joint Commission, a consortium of officials from the United States and Canada who study the Great Lakes.

Chemical engineers at Rice University have found a new catalyst that can rapidly break down nitrites, a common and harmful contaminant in drinking water that often results from overuse of agricultural fertilizers.
Nitrites and their more abundant cousins, nitrates, are inorganic compounds that are often found in both groundwater and surface water. The compounds are a health hazard, and the Environmental Protection Agency places strict limits on the amount of nitrates and nitrites in drinking water. While it’s possible to remove nitrates and nitrites from water with filters and resins, the process can be prohibitively expensive…
In a new paper in the journal Nanoscale, Wong’s team showed that engineered nanoparticles of gold and palladium were several times more efficient at breaking down nitrites than any previously studied catalysts. The particles, which were invented at Wong’s Catalysis and Nanomaterials Laboratory, consist of a solid gold core that’s partially covered with palladium.

“Serious health and safety concerns” over nanoparticles in the newest paints and coatings is driving innovative European technology to make those products safer and less environmentally damaging.
The idea: Remove the particles.
The EU-funded NANOFLOC project, now nearing the midway point, aims to develop a system that can remove nanoparticles from coating wastewater in an efficient and cost-effective manner to prevent pollution.
