WILTON – Goss Park, the town’s only recreation area, has been closed by the discovery of e coli bacteria in Stony Brook which feeds the park’s swimming pool. The source is currently unknown, but the recent heavy rains are suspected as a main contributor.

The park, located on Route 31 north in Wilton, is funded by both Wilton and Lyndeborough and is open to all residents..

At the meeting of the Select Board on Monday, July 10,Selectman Kermit Williams said he had met with the Lyndeborough selectmen in an emergency session on Friday, July 7. Stony Brook runs through much of Lyndeborough and the park is near the town line.

“They had a concern about a failed septic system, but more recent tests could point to something else. A vernal pool tested very high. There’s been so much rain it could have washed (animal waste) into the pool. I suggested that we test the e coli DNA to determine if it is human or animal.”

Selectman Chair Matt Fish noted the impact on both towns by closing the park. “We need to help Lyndeborough reach a resolution.” He mentioned several other beaches in the state that have also been closed.

The park directors said they are increasing the water testing and the park is opening for non-water activities.

Williams said, since Wilton has an agreement with the Milford Wastewater Treatment Plant, “water testing for e coli can be done there,” saving the $55 per test.

Daily testing was suggested.

Peter Howd, Wilton’s representative to the Souhegan River Advisory Council, also attended the meeting with Lyndeborough selectmen.

“The (test) numbers were off the chart. We are concerned about public health threats, every one who uses Stony Brook.” The brook is popular with local fishermen.

It was suggested that water samples be taken both at the inlet to the pool and in the park itself.

Williams said, “In this heat, the kids need a place to swim.

Goss Park.was created in 1958 by the Wilton-Lyndeborough Youth Center on a 14-acre parcel donated by Jennie Goss. The WLYC officially incorporated in 1977.

The park offers, in addition to swimming lessons, arts and crafts, basketball, tennis, nature trails, library reading programs, special programs for teens, and a snack bar. It is supported by both towns and by family memberships.
