Feedback post on Bioretention: Filter media

In table 2, related to laboratory testing of bioretention filter media for hydraulic conductivity, a specification for the level of compaction of the media sample prior to testing (e.g., 75 to 85% maximum dry density) should be provided and refer to ASTM D1557 or ASTM D 698 for lab procedures. It should also specify a lab test method for KSAT (e.g., ASTM D2434 which is being worked on and due for renewal/update soon so okay to still use despite being currently "withdrawn" on the ASTM website).
