compares water quality in local streams

The stream meanders
through protected forest, making it a perfect study site for the North
East Water Resources Network, a three-state, $6 million initiative to study how
climate variations may play a role in water quality and quantity.
Once a week this
summer, University of Rhode Island graduate student Britta Anderson
and two undergraduates from Salve Regina University checked the pulse of
one of the many tributary streams that collect in the Scituate Reservoir before
flowing as one into the Pawtuxet River and then into Narragansett Bay.
For comparison, the
student researchers also studied two freshwater sources in Middletown
— Bailey’s Brook, which courses through an urban location, and the
Maidford River, surrounded by agricultural land.
High tech sensors at all three
sites measured water quality parameters like temperature, acidity and chemicals
present, data that are particularly useful in understanding what happens during
extreme storm events.
“We counted the pollution
intolerant and tolerant species to help us understand water quality,” said
Anderson, who grew up in Prior Lake, Minn., and now lives in Coventry, R.I.
“For example, stoneflies are pollution intolerant, so their presence tells us
the water quality is rather good here. But, on Aquidneck Island, we’ve rarely,
if ever, found stoneflies, but generally find the more pollution tolerant
species.”
The project is part of
the National Science Foundation’s Experimental Program to Stimulate
Competitive Research and funded by a three-year grant awarded to Rhode Island,
Delaware and Vermont. URI Professor Arthur Gold serves as the project director
for Rhode Island.
The collaboration in
multiple disciplines – from hydrology and economics to chemistry and marine
robotics – is gathering data, assessing water quality, and gauging how better
information affects land use and management decisions. With the states’ varying
local climates, precipitation, and population density, the data compiled will
provide valuable insight to both scientists and policy makers.
At the same time, the
project offers a unique training ground for graduate and undergraduate students
at universities in all three states to gain hands-on research experience.
Anderson is pursuing a
master’s degree in biological and environmental science with a focus on
hydrology. She is planning to wrap up her studies in May 2017.
“The project provides
practice on the concepts I’m learning about in school,” she said. “This last
year, I took several classes in hydrology. Now, it’s great to get out in the
field and learn how the concepts apply and what they mean for Rhode Island.”
Prior to the start of the
summer fellowships, the Rhode Island research team hosted about 20
undergraduates from the three states for a three-day orientation at Salve
Regina that included an introduction to the project, watershed tours, science
communication training, and a fish trawl.
At summer’s end, the students gathered at URI to deliver their
research findings in rounds of two-minute talks and poster presentations as
part of the 2016 North East Water Resources Network’s Undergraduate
Research Symposium.
