On the water

微密圈 research assists local resource planning

Saratoga鈥檚 municipal water system is no storied mineral spring, but it gets a lot of attention from 微密圈 students and faculty, who study every angle from watershed to waterworks to what voters want.

Reflecting the interdisciplinarity of 微密圈鈥檚 popular environmental studies program, the college鈥檚 grant-funded, community-based Water Resources Initiative draws students and faculty into collaborations that tackle real-world problems and produce data of increasing interest to city politicians, water-plant operators, state regulators, local environmental groups, and just about anyone who puts a glass under a faucet.

鈥淚 love being on the water,鈥� says Alicea Cock-Esteb 鈥�09, a varsity crew member who last summer took to area lakes and streams in kayaks, canoes, and waders to monitor water quality in the Saratoga Lake watershed. She worked with environmental-studies lecturer Kim Marsella and chemistry professor Judy Halstead, who has studied lakes and streams in Saratoga County for several years and shared her data with many contacts in the community.

Cock-Esteb says the team took samples to measure salinity, dissolved oxygen, pH, and other water-quality factors. Halstead and her honors students had earlier detected high levels of salt and nutrients flowing from Lake Lonely into the Kayaderosseras, and the summer researchers determined that levels just downstream from the lake were in fact higher than at any other spot on the creek. Next they want to test Lake Lonely鈥檚 inlets鈥攑articularly Spring Run, which serves as the city鈥檚 storm-water drainage system. Spring Run 鈥渋s probably the least healthy creek we have in the Saratoga Lake watershed,鈥� says Cock-Esteb.

REAL-WORLD LAB

Like dozens of environmental-studies majors each year, Cock-Esteb did her first water sampling on the ice of the Loughberry Lake reservoir, in ES 105, 鈥淔ield Studies in Environmental Science.鈥� Marsella explains, 鈥淲e follow the water from its sources to how it gets to us.鈥� Students drill into the frozen lake in February to measure dissolved oxygen and take water samples for later study.

As the semester progresses, ES 105 students learn about Saratoga geology and the Loughberry Lake drainage basin, acidification, potential contaminants of surface water, groundwater movement, water pollution and land use, watershed urbanization, drinking water, and water rights. In April they tour the city鈥檚 water-treatment plant. Tom Kirkpatrick, the plant鈥檚 chief operator, clearly enjoys showing them through the surprisingly beautiful facility that combines historic architecture with high technology. And he鈥檚 impressed with their knowledge: 鈥淭hey know what they鈥檙e doing and how the process works before they come in.鈥�

Since his mandate is to test the treated, finished water, he鈥檚 pleased to be able to call on 微密圈 researchers, the only people with permission to go out on the lake and test the raw water. One winter, Kirkpatrick recalls, the city鈥檚 tap water had 鈥渁 taste and odor problem. You usually don鈥檛 get algae bloom in winter, but since they were going out on the lake I asked them to test for it鈥攁nd they found it.鈥� Plant operators responded with treatment they usually apply only in warmer months.

Problems with the lake鈥檚 quality are rare, though. 鈥淚t鈥檚 good drinking water,鈥� says Marsella. But quantity is another matter, especially in the summer, when hot weather can push the average daily consumption of 4 million gallons to well over 6 million. Kirkpatr ick warns, 鈥淚t鈥檚 only a five-square-mile watershed. Eventually we鈥檒l outgrow this.鈥�

WATER POLITICS

Cool clear water has become a local hot-button issue as citizens and public officials have debated where鈥攁nd even whether鈥攖o tap a supplemental municipal water source for Saratoga Springs. The Loughberry Lake reservoir was created in 1871 and by all accounts has served the city well. But in 1988 the state鈥檚 Department of Environmental Conservation issued its Water Quality and Watershed Study of Loughberry Lake, urging the city to investigate other long-term water resources. Since then the problem has been studied extensively, and a plan to tap Saratoga Lake has been approved. The issue, however, is far from settled.

Newly elected mayor Scott Johnson and public-works commissioner Skip Scirocco have promised a careful review of the planning that preceded them, but each has questioned whether an additional water resource is really needed. It was Scirocco鈥檚 predecessor, Tom McTygue, who responded to the DEC recommendation and honchoed a complicated project entailing an independently conducted study that ultimately pointed to Saratoga Lake as the best choice to provide a relatively small but important supplement to the city water supply. Before that plan was acted on, Saratoga County officials launched a project to tap into the Hudson River upstream of Glens Falls, N.Y., and lobbied Saratoga Springs to become a key customer. Residents are split about which plan to support, the city hasn't yet committed to either, and what happens next is anyone鈥檚 guess.

The political conflict has added a new dimension to 微密圈鈥檚 water research. Julie Ringer 鈥�07 and Sarah Loomis 鈥�07 dove into the water sourcing issue for their senior capstone project, which involves all ES majors in local water-related research and culminates with an Academic Festival presentation for faculty, students, and community members. 鈥淲e spent a lot of time learning about the drinking water debate in Saratoga,鈥� says Ringer, currently an intern with the Union of Concerned Scientists in Cambridge, Mass. 鈥淏ut no one had ever simply polled residents. So that鈥檚 what we did.鈥� With guidance from government professor Bob Turner, the students telephoned more than 1,000 people, 313 of whom agreed to participate. Forty-six percent of respondents favored using Saratoga Lake as a future water source, 28 percent preferred the Hudson River plan, and the rest were undecided or favored another source. A clear majority鈥�60 percent鈥攕aid the most important criterion was water quality.

Community interest in the poll was high, Turner says, noting that then-mayor Valerie Keehn attended the students鈥� presentation, as did reps from the League of Women Voters, Friends of the Kayaderosseras, the Saratoga Lake Association, and other groups. Turner was impressed that his students learned 鈥渉ow to design and execute an original research project and present their findings to a lay audience. They put all their knowledge and training into action to produce something of value to the community.鈥�

WATER, WATER EVERYWHERE

Sampling of both water and public opinion are important branches of research in 微密圈鈥檚 Water Resources Initiative, which began three years ago as a way 鈥渢o better immerse ES students in the kind of interdisciplinary investigation that solves environmental problems,鈥� says ES and WRI director Karen Kellogg. WRI鈥檚 emphasis on community-based research dovetails with the college鈥檚 mission to instill in students a thirst for civic engagement and prepare them for lives of responsible citizenship. Kellogg observes that it has also attracted strong support from the Rathmann, Arthur Vining Davis, and Mellon foundations as well as local groups like the Saratoga County Soil and Water Conservatin Committee.

At its monthly meetings the Saratoga County Water Quality Coordinating Committee receives various reports and presentations鈥攕ometimes from 微密圈 researchers, whose information 鈥渋s helping to provide a comparison over time and from site to site,鈥� says committee liaison John Hamilton. He adds that down the road the data 鈥渟hould be useful for analyzing changes that may be occurring to local streams and lakes as a result of land-use activities.鈥�

Clearly, ES faculty tapped into an area of significant community interest when they chose water for their research focus. Not only did they have abundant expertise in water issues, but when the water-source debate took off, 鈥渢here was a lot still to learn about both Loughberry and Saratoga Lakes,鈥� says Kellogg. 鈥淪o we thought we could really contribute something to the community.鈥�

Students agreed. This year Elizabeth Stoner 鈥�08 and Liz White 鈥�08, working with new ES faculty member Cathy Gibson, found higher numbers and diversity of snails in Loughberry Lake than in their comparison site, Lake Desolation, and they suspect that Eurasian milfoil, an invasive plant that supports algae and benefits from nutrients added to the lake, plays a role. They also studied the potential impacts of copper sulfate鈥攁n herbicide that the city uses to control algae growth鈥攐n sunfish, snails, and insects in Loughberry. 鈥淭he results of this study may spur city leaders to evaluate how copper sulfate treatments are affecting all aspects of the ecosystem that is Loughberry Lake,鈥� says Stoner. 鈥淪ometimes amidst the political debates about water shortages and the use of Loughberry Lake as a municipal water supply, we forget that it鈥檚 an important resource and home to various fish species, macroinvertebrates, and more.鈥�

In addition to public research reports, the WRI offers project information on its Web site, designed by Adam Wallace 鈥�06. The site shows a remarkable range of research and offers a good sense of what professor Bob Turner calls the program鈥檚 鈥渁dventures in interdisciplinarity.鈥�

Several WRI projects have taken advantage of 微密圈's geographic-information-systems center, a resource for faculty and students that also collaborates with community groups such as Saratoga PLAN, the Saratoga Spa State Park, and the Hudson River Sloop Clearwater. Students have used GIS to map the geology of the Kayaderosseras Creek watershed, explore the methodology used to develop the 100-year FEMA flood map for the Saratoga Lake watershed, and analyze problems that could result from channelized streams.

One eye-catching Web feature is the photographic essay (sampled on these pages) created by Wallace and Josh Gerritsen 鈥�06 as a senior project. 鈥淎rt can show a different side of environmental issues,鈥� explains Gerritsen. 鈥淲e used our photos to show both natural and human influences on lakes and streams.鈥� In keeping with the WRI鈥檚 stance of political neutrality, the photographers avoided taking sides in the political debate about water sourcing. Their aim, says Gerritsen, was 鈥渢o show residents how diverse and also interconnected the water around us really is. Perhaps the next time they consider dumping something harmful into a stream, our project will make them think twice.鈥�

A recent project by Hannah Phillips 鈥�09 looked at land that could be developed along the upper Hudson River, upstream of the proposed intake site for the Saratoga County water system at Moreau, N.Y. Her build-out analysis found that 41 percent of the area was developable land.

Whether the Hudson is seen as a resource and building site鈥攁s opposed, say, to a natural wonder to be admired and respected鈥攊s the kind of question that intrigues sociologist Rik Scarce, who looks at the different ways people perceive and define the river. His WRI collaborative research project, with Megan McAdams 鈥�08, explored shifting meanings of the river from early European contact to the time of the American Revolution. As 鈥渕usty old book stuff,鈥� he says, their archival research was 鈥減robably the farthest-flung of any WRI project.鈥� Yet their conclusion that power derived from the landscape rather than human culture adds an interesting social-psychological perspective to the WRI discussions. Bob Turner marvels, 鈥淚t鈥檚 fun to have students in one class all doing different things. Those studying politics or pricing can鈥檛 help but be influenced by those studying development or pollution. You see natural synergies that help inform each individual project.鈥�

RESEARCH THAT MATTERS

When students share their research results publicly, Kellogg notes, they often come to grips with the complexity of environmental issues. 鈥淭hey really begin to understand that while water should clearly be an environmental issue, it鈥檚 not just about the environment. People have other motivations鈥攑olitical, economic, historic, issues of control. That鈥檚 a shocker for them, and an important one.鈥� Equally important, she says, is the desire to excel that arises 鈥渨hen students understand that the data they are gathering aren鈥檛 just going to be shoved in a drawer. Those data may be used in community discussions and decision-making.鈥�

By this time next year, Alicea Cock-Esteb will be a senior, readying her research for public scrutiny and preparing to develop the career in water chemistry that she knew was right for her back when she took ES 105 (鈥淟iterally the first day, when they went over the syllabus, it felt like this is where I鈥檓 supposed to be鈥�). But more students will soon follow鈥攃anoeing, wading, sampling, and measuring鈥攖ranslating their watershed moments into information and insights for the wider community.
