Abstract

The study examined several options for material mixtures in bioretention cells to keep water cleaner and cut down on pollution into urban storm sewers.

Key Question

If iron fillings are mixed with soil media in bioretention cells, will they retain phosphorus without hindering plant growth?

Findings

Iron fillings are inappropriate for bioretention cell media because they leach out as particulates, cement the soil, and reduce plant growth. Iron fillings did not significantly retain phosphorus.
