GUILDERLAND — The town is pursuing a state grant to install a greensand filtration system at its drinking water wells.

Consequently, the town board on Thursday scheduled a public hearing for Friday, Nov. 19, at noon, to adopt a State Environmental Quality Review Act determination. This allows the required 30 days for comment between the board’s Oct. 19 adoption of the resolution and the public hearing.
Mary Beth Bianconi with Delaware Engineering, which is handling the application, explained that the town has three wells. One is used in the summertime when water use peaks in town; the other two wells are unused because they have high levels of iron and manganese.
