 Sites with shallow bedrock should take an approach similar to those with shallow groundwater, detailed above. Bedrock infiltration rates are highly variable and will need to be determined by a geotechnical engineer and/or through discussion with WRE staff. Because bedrock may have a more direct path to groundwater, an additional 1 foot of sand (finer than coarse) below the engineered soil layer is necessary to meet separation requirements.
+===== Prohibitions =====
+Wisconsin Chapter 151 has [[https://docs.legis.wisconsin.gov/code/admin_code/nr/100/151/iii/124/3/a|infiltration prohibitions]] for certain land uses, but these are not exemptions. Sites with prohibited areas are still expected to meet the infiltration standard.
