Havens Study Will Continue
By Marissa Maier
Members of the Stony Brook University research team, who have been testing for harmful levels of bacteria at Havens Beach in Sag Harbor for almost a year, say their work will continue through the summer. Chris Gobler, a Stony Brook Southampton associate professor and the director of the Coastal and Estuarine Research Program, has spearheaded the team with help from graduate and doctorate students, like Florian Koch.
Koch was on hand at a recent Coastal and Estuarine Research Program environmental symposium with a poster showing the testing data as of March 2009. The team, in conjunction with Peconic Baykeeper Kevin McAllister, has been studying the site since April 2008 and say the data they have collected is alarming.
“I think the data speaks for itself … The water quality in this area is being negatively affected, but this isn’t a new issue,” said McAllister. “Hopefully, this report will place a spotlight on Havens and be a call to action for the village and the harbor committee.”
According to data presented by Koch at the symposium, levels of harmful bacteria have exceeded healthy thresholds for bathing and shell fishing throughout the year. From April 2008 to early April 2009, testing from the receding water stations located in the bay showed bacteria levels were above adequate standards for shell fishing 31 percent of the time during testing and 44 percent of the time for bathing thresholds. These numbers pertain to results collected from three testing stations set-up in the water.
At three “source” stations — which consist of a ditch, a culvert leading to the beach and a steady stream of water flowing from the beach into the bay — levels were even higher. When averaging the whole year, the source station surpassed healthy standards 70 percent of the time for shell fishing and 60 percent of the time for bathing.
Because the source stations indicated more frequent high bacterium levels than the receding water stations, Gobler said his team studied the source stations to ascertain where the bacterium was coming from. That research is ongoing.
Koch and his fellow researchers tested the beach on a monthly to bi-monthly basis, but did responsive testing after heavy rainfalls. The ditch, or the first “source” station, collects storm water run-off for a 275-acre area, said McAllister, through a complicated network of piping. According to McAllister, the water collected at the ditch, seeking the lowest elevation, then flows into Havens Beach by way of the culvert. Gobler added that it is possible the ditch is also subject to ground water seepage.
As the Stony Brook team has been conducting their research, Suffolk County has been testing the waters of Havens Beach.
“By law, the county tests Havens and all other beaches on a weekly basis,” said Sag Harbor Village Mayor, Greg Ferraris. “Suffolk County has never issued a directive to close the beach.”
McAllister said the discrepancy between the county’s and Stony Brook’s results could be attributed to the Stony Brook team’s responsive testing after heavy rainfall. He noted that contaminates are more likely to flow into the ditch when it rains, but in drier weather are likely to stay put.
Village planner Richard Warren, who also operates an environmental consulting firm, said the discrepancy could also be attributed to different testing methodologies. He added that he would like to sit down and review side by side the county’s results and the Stony Brook results, with the help of Chris Gobler.
“With Kevin [McAllister] and Chris [Gobler], I hope we can set aside a testing protocol and start having a dialogue,” said Warren.
Village officials said they weren’t contacted before the yearly results were presented at the symposium and felt this went against a communications protocol established by both parties.
“We expected once the testing was complete to meet and discuss the findings,” Ferraris noted. “[We hope] to review the data and come up with a plan of action.”
Although the Stony Brook team planned to test for only a year, Koch said they would continue through the summer with no fixed end point in mind. Gobler added that the team believes it is important to continue monitoring the site and he also wishes to set up testing sites to the east and west of the beach.
McAllister noted that beyond testing, actual measures would need to be implemented in the future.
“Havens Beach and this ditch is a problem,” he said. “But developing this data will hopefully lead to a remediation project. It is going to cost money to deal with this and I recognize the challenges the village is facing. Are they going to be able to finance a project that is going to eliminate this pollution problem?”
