Grafton Water District (GWD or Supplier of Water) is a community public water system (PWS) located in the Town of Grafton, Massachusetts, serving approximately 10,700 people per day. Water for the PWS is obtained from five active groundwater sources, treated at four Water Treatment Plants (WTPs), and stored in three atmospheric finished water storage tanks across three pressure zones. The GWD also maintains interconnections with six other water systems. The Worcester Street Well (2110000-02G) is a gravel packed well that operates as a single source with a permitted capacity of 1.01 MGD. The new treatment facility will be designed for an average flow of 500 gpm and a peak flow of 760 gpm. Water from 02G is treated for pH adjustment with potassium hydroxide (KOH) and disinfection with chlorine gas. As described in the ENF, the Grafton Water District (the "Proponent") plans to construct a 6,400-square-foot Water Treatment Plant (WTP) to treat per-and polyfluoroalkyl substances (PFAS) detected in the water supply wells. The WTP, which will be built on approximately 2 acres of a 11.15-acre forested parcel and will consist of a single-story building with treatment areas, a control room, a bathroom, and associated stormwater and utility infrastructure (water mains, fencing, generator, etc.). The site is currently developed with a water pump station that provides potable drinking water to the Town of Grafton. The project includes 750 linear feet of new water main, which will connect the new WTP to the existing water main piping that flows towards Worcester Street. The site presently has a water pump station and maintains a mowed area on about 1 acres of the site around the existing pump station building and well enclosure. The Project will clear and grub 1.44 acres of the 11.15 acres site to construct a new PFAS treatment building, surrounding paved driveway, relocate a monitoring well, and construction ofstormwaterstructures including an infiltration basin. Portion of the work are located within the 100' Buffer Zone. After construction, the project will result in 0.45 acres of additional impervious surfaces. Access to the site will continue to be from Doris Drive. A. Items of work include but are not limited to the surface preparation and coating of the following: 1.
