As oxygen is necessary to support life in aquatic ecosystems, its measurement is essential for gauging the overall state of water bodies; in one of the study's surveys, more than one-third of the 90-kilometer length of the river system failed to meet the New York water quality standard.
This research has shown the importance of utilizing innovative technology to manage and monitor complex aquatic ecosystems in urban settings. Oftentimes, programs for treating water systems are implemented without robust data to identify the true source of the problem. The value of this case study comes from the large number of cause-and-effect relationships that were clearly identified through the monitoring system.
Steven Effler, director of research at the Upstate Freshwater Institute and Charles Driscoll, University Professor of Environmental Systems Engineering in the L.C. Smith College of Engineering and Computer Science at Syracuse University, presented recently the results of this Syracuse Center of Excellence Collaborative Activities in Research and Technology Innovation (CARTI) water research project—"An Intelligent Urban Environmental System (i-UES) for Central New York Water Resource Management"—to SyracuseCoE's Scientific Advisory Committee. SyracuseCoE awards CARTI projects using funds from the U.S. Environmental Protection Agency. Co-authors of the study are Anthony R. Prestigiacomo and Adam J.P. Effler of the Upstate Freshwater Institute.
While much attention has been given to the impact of rivers on lake water quality, there had previously been little done to track the effects of lake outflows on receiving rivers. The water quality of these rivers is of great concern in order to protect their multiple uses—recreation, navigation, power generation and waste discharge—and to support regional development. Currently, the ability of the water systems to absorb the waste sent into them is significantly reduced.
"This study illustrates some of the complexities and challenges in managing urban water systems," says Driscoll. "There are multiple factors associated with the low oxygen concentrations in the Three Rivers system. As a result, multiple approaches will be needed to improve the oxygen status of the river."
To assess the water quality of such large river systems, the study conducted eight longitudinal surveys—four in summer 2007 and four in summer 2009—collecting data from more than 50 sites, utilizing special instrumentation that measures temperature, conductance (the capacity to conduct electricity), turbidity (muddiness of water due to stirred up sediment), chlorophyll levels and dissolved oxygen.
The "boundary conditions" that show the baseline measurements were collected by solar-powered robotic monitoring platforms at the outflows of each lake.
With much conclusive evidence pointing to the oxygen depletion in the Three Rivers system, the research team recommends long-term, routine monitoring of the system, utilizing robotic systems. The researchers suggest that simply improving processes at individual wastewater treatment plants will not be enough to impact the system, and the team must continue to define dynamics and provide insights for rehabilitation. A water quality model can then guide management decisions for a recovery process.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
