 Floating Wetland Islands filter pollutants at Frances Slocum
"Floating Wetland Islands, designed and installed by Princeton Hydro, are helping to reduce algae blooms and improve water quality at Frances Slocum State Park.

State grant will help battle invasive plant in Harveys Lake
"Harveys Lake awarded $110,000 from a Clean Water Fund grant to help eradicate the invasive aquatic species hydrilla. Dr. Fred Lubnow, Director of Aquatic Programs at Princeton Hydro, explained to the Harveys Lake Borough Council that the grant will be used to combat the lake's highest densities of hydrilla."

 Old Meriden Dam Torn Down to Make Way for Fish
"Princeton Hydro is on-site at the Quinnipiac River for the Carpenters Dam removal. The removal of this dam opens up 16 miles of river, allowing fish to swim upstream, supporting the expansion of freshwater mussels and other aquatic life, giving outdoor recreationalists more flexibility, and providing countless other benefits."

Spring Creek Work to Start this Month; Queens Chronicle
"The work is being done by Princeton Hydro, a New Jersey-based engineering firm that has worked on environmental projects across the country." 


Blue-Green Algae Blooms Plague Area Lakes:, The Journal News
"There are three main causes of blue-green algae blooms – phosphorus pollution, high temperatures and a lack of natural water flow – said Fred Lubnow, director of aquatic programs at New Jersey-based Princeton Hydro, a consultant to Putnam County on water quality issues." 

Friends of Lake Afton move forward with algaecide project in preparation for Harvest Day, plan fundraisers for later this fall in Yardley: Bucks Local News
"There’s more involved than just applying the algaecide, according to Churm. 'We are also conducting water quality sampling and monitoring to understand the water chemistry of the lake. That is an ongoing operation. Once we have conducted our final sampling later this week, we’re going to provide the Friends of Lake Afton recommendations on the future management of the lake.'” 

Non-profit hires hydrology firm to recommend ways to address spreading algae problem at Yardley's picturesque Lake Afton: Bucks Local News
“'Once we'veve collected all the data and reviewed it, we will provide the Friends of Lake Afton with recommendations for the future management of the lake,' explained Scott Churm... 'Our goal is to try to improve the overall water quality for aesthetic reasons, recreation reasons and most importantly, for water quality.'” 

Large-Scale Watershed Protection Devices Come To [Toms RIver High School] North
"Newly-dug devices to help protect the Barnegat Bay watershed have come to the home of the Mariners. Toms River High School North, through the American Littoral Society and Princeton Hydro, will have tree boxes, manufactured treatment devices and other elements to help stem the tide of pollution in Long Swamp Creek in the watershed."

Floating Wetland Islands; Greenlife Pennsylvania
"Wetlands are a great, natural way to filter out contaminants from streams and rivers. But what about preserving the quality of lakes and ponds? Residents of Harvey's Lake in Luzerne County, and the lake community called The Hideout in Wayne County have found an answer. They're getting help from a company called Princeton Hydro." 

Sandy at 2 [years later] - Improvements Slow but Steady
"'We may not have another Sandy in a while, but we're going to have repeated flooding,' said John A. Miller, a flooding expert with the New Jersey Association for Floodplain Management, a public-private group. 'We have very vulnerable areas.'" 

Lake Hopatcong installs Floating Wetland Islands to help curb algae growth; Daily Record
"Through a non-point source pollution grant awarded by NJ Department of Environmental Protection to the Lake Hopatcong Commission, Jefferson Township was able to install a system known as Floating Wetland Islands to deliver better water quality to Ashley Cove and Lake Hopatcong." 

Less Phosphorus Reported in Lake Hopatcong; Lake Hopatcong News 
"The phosphorus load in Lake Hopatcong has been reduced by 33 per cent over the past nine years, said Fred Lubnow, director of aquatics programs at Princeton Hydro, at the monthly Lake Hopatcong Commission meeting Monday night." 

Flooding Risk Rises Statewide
"The engineering firm Princeton Hydro was hired to open up a piped-in water system, re-exposing 1,200 feet of natural stream known as Petty’s Run. Geoffrey Goll, a founder of Princeton Hydro, said that only minutes after the waterway was reopened, 'kids came down and started picking frogs out of the stream.'”

Using Floating Wetland Islands to Reduce Nutrient Concentrations in Lake Ecosystems
In lake-front communities, the implementation of beneficial wetland systems can be limited by a lack of space. Floating Wetland Islands offer an innovative solution to space limitations and provide many of the same benefits as traditional wetlands. They are mobile, temporary wetlands that can be strategically placed to maximize their nutrient-reducing and habitat-building capabilities.
