Algal blooms reduce DO levels in the water, killing plant and animal life –from marsh grasses to blue crabs to rockfish. Learn how De Nora TETRA™ Denite® technology is treating 450+ MGD in the Bay.
The question of how to get the most out of the data that we collect as an industry was central to the Sensing in Water Conference recently hosted by the Sensors for Water Interest Group (SWIG). The two-day conference highlighted several themes on how to get the best of the data that the Water Industry collects and how to make our measurements “meaningful.” Chief among those themes was greater collaboration among the different stakeholders, including water companies, universities, and the supply chain.
New water brings new challenges, such as overcoming heightened regulatory standards and consumer wariness. To ensure water quality and quell concerns, utilities moving toward alternative water sources might also consider updating their monitoring technology.

Cities all over the country have been prioritizing clean water through a variety of different programs and the City of Brotherly Love is among the ranks.
For years, I’ve been standing on my deck in San Francisco, looking south to Silicon Valley for innovation in water efficiency. But I’m starting to realize that I might have been gazing in the wrong direction. Maybe I need to turn around and look north, over the spires of the Golden Gate Bridge, toward the Emerald Triangle in Humboldt, Mendocino and Trinity counties, the hotbed of California’s newly legalized commercial cannabis production.
Election season is in full swing and while it may not be the “hottest” topic being debated amongst presidential candidates, the topic of water isn’t being ignored as we approach November. Several candidates have addressed the challenges plaguing water and wastewater systems nationwide.
It’s no secret that municipalities across the country are facing budget constraints.
While most of the country was seeing red, white, and blue this past Fourth of July, many Florida residents were seeing green.
New York City treats 1.3 billion gallons of wastewater a day across its 14 wastewater treatment plants. The city has seen a precipitous drop in fecal coliforms, with the NYC Department of Environmental Protection (DEP) reporting that fecal coliforms per 100 mL of water has fallen from 1,000 in 1972 when the Clean Water Act was passed to closer to 10 as of 2009.
During the long campaign, you ran on a platform of change, and since the election, you have charted a course toward improving our nation’s infrastructure. I urge you to focus some of that change and a significant portion of those infrastructure improvements on the one issue at the center of survival for all Americans, regardless of whom they voted for — water.
It may seem farfetched, but the reality is that many Americans don’t have regular access to clean drinking water.
California is home to some of the world’s most creative minds, top universities, productive farmland, groundbreaking industries — and one of the most epic droughts. The state has endured five years of drained reservoirs and groundwater reserves tapped so aggressively that the land subsidence caused by pumping has been literally seen from space. This indicates in no uncertain terms that it’s time to get all hands on deck. Private companies, universities, irrigation and drainage districts, municipalities — it’s time to pull together into public-private partnerships to address water challenges that face California and so many other regions of the world.
More than 20 years ago I wrote a Master’s Thesis about software tools that could be put together with EPA SWMM to create a toolbox for very long term continuous simulation for stormwater and watershed simulations. I was inspired at the time by Dr. William James who was my advisor for that research.

The sky is blue, grass is green, and, someday, your pumps are going to clog. It’s just another fact of life — or is it?
Angelo Mazzei has always thought locally and acted globally. Born and raised in California’s San Joaquin Valley — one of the world’s most productive farming regions — Angelo worked for his uncle’s 10,000-acre farming operation after graduating from college. There he saw a pressing need for a system that would allow farmers to safely and efficiently inject fertilizer into their irrigation water — a task made even more challenging with the 1968 introduction of high-pressure water supplies through the California Aqueduct, a 400-mile-long water conveyance system. A new approach was vital.
