APPENDIX D - DRASTIC MAPPING IN E. BARNSTABLE AND W. YARMOUTH 



Cape Cod Aquifer Management Project Final Report Page D-3 



followed (in descending order) by depth to water, soil media, aquifer 

 media, net recharge, impact of the vadose zone and hydraulic conductiv- 

 ity. DRASTIC was most successfully applied in the Barnstable Outwash 

 Plain region of the study area because of the availability of extensive 

 well information. In contrast, no well information was available for the 

 Sandwich Moraine portion of Zone I and the ranges for all DRASTIC factors 

 except for net recharge, soil media and topography had to be estimated 

 from areas of the moraine outside of Zone I. 



Acknowl e d gme n t s 



I am grateful to Kim Franz of the U.S. Environmental Protection Agency and 

 Beth Flynn of the U.S. Geological Survey for their assistance in producing 

 the DRASTIC map of Zone I.
