Bioretention amendment with fungi study

Study questions

The study’s sampling quality assurance project plan provides information on the sites and study design.

• Do fungal and/or plant amendments improve the effectiveness of the default bioretention soil mix to reduce metal, fecal coliforms, and nutrient pollution from highway runoff?
• Are the amended mixes still capable of preventing toxicity to aquatic organisms?

Study findings

Monitoring is underway through 2018.
