In previous experiments, we have studied leaching of dissolved organic
carbon (DOC) and nutrients from compost columns under worst
case scenarios, i.e., by leaching pure compost columns with deionized
water (Mullane et al., 2015). We have also mixed compost with biochar,
but have not observed reduced leaching (Iqbal et al., 2015). In this study,
we expand these experiments by using real stormwater and a bioretention
