The 2017 guidance from New Hampshire specifically rules against the inclusion of compost in their bioretention media.<ref>UNHSC Bioretention Soil Specification. (2017).

The use of wood chip has been common in New Hampshire for some time, in this 2006 thesis 20 % was incorporated into all of the test cases to match current practices at the time. <ref>Stone, R. M.
