Their German-style lagers are brewed with water from an artesian well that draws from New Hampshire's largest stratified drift aquifer, the Ossipee.
An analysis of peatland distribution and specific glacial drift types in Noble County showed that peatlands were significantly more frequent in mixed till and stratified drift in lineated form associated with collapse of sub-ice tunnels and open ice-walled channels.
The importance of these processes in the Saginaw Lobe region is supported by the presence of mixed stratified drift in chaotic form and the lack of uniform ground and end moraines (Gray 1989).
The observed frequency and distribution of peatlands in the various drift-types across the county was similar to expected values, with the exception of MB (areas of morainal topography of Trafalgar Formation), TB (loam till of Trafalgar Formation), OF (outwash fan deposits; sand and gravel), G (ice-contact stratified drift, sand and gravel as isolated ridges), and 77' (mixed till and stratified drift in lineated form associated with collapse of sub-ice tunnels and open ice-walled channels) (Fig.
While both peatlands and wetlands were significantly more frequent in TT, wetlands additionally were unusually abundant in O (undifferentiated outwash, mainly as valley train; sand and gravel), OP (intensely pitted outwash), and TG (mixed till and stratified drift in chaotic form).
This paper concentrates on three major issues considered by RIDEM staff as it delineated WHPAs to large wells completed in stratified drift.
The geology of Rhode Island may be generally described as fractured crystalline bedrock overlain by till and/or stratified drift from the Wisconsin glaciation.
The categories are (1) large wells completed in stratified drift, the subject of this paper; (2) large wells completed in bedrock; and (3) small wells.
The delineation methodology for the 87 large wells (37 wellfields) completed in stratified drift used the Uniform Flow Equation (UFE) (McWhorter et al.
Analytical modeling for large wells completed in stratified drift
Rhode Island's stratified drift aquifers can appropriately be modelled with this equation because of their gently sloping water tables and transmissive, porous media.
For most of the large wells in stratified drift, there was more than one value of Q, K, b, and i available for solving the UFE.
