§ 17.15.505. Rating system.

Aquifer recharge areas are categorized according to the following standards and those contained in Appendix B located at the end of this chapter.

A.

"Category I, extreme aquifer sensitivity" are those areas which provide very rapid recharge with little protection, contain coarse soil textures and soil materials, and are derived from glacial outwash materials. The predominant soil series and types are those listed as Category I in Appendix B, located at the end of this chapter.

B.

"Category II, high aquifer sensitivity" are those areas which provide slightly lower recharge, also provide little protection, and are from materials of glacial deposit. The predominant soil series and types are those listed as Category II in Appendix B located at the end of this chapter.

C.

"Category III, moderate aquifer sensitivity" are those areas with aquifers present but which have a surface soil material that encourages run-off and slows water entry into the ground. The predominant soil series and types are those listed as Category III in Appendix B located at the end of this chapter.

D.

"Category IV, low aquifer sensitivity" are those areas of low groundwater availability and whose soil series are derived from basaltic, andesitic or sedimentary rock; or ancient glacial till (more consolidated, more clays at surface), and which have not formed geological formations that provide abundant groundwater. The predominant soil series and types are those listed in Category IV in Appendix B located at the end of this chapter.
