Recent Publications

Biochar role in improving pathogens removal capacity of stormwater biofilters

Biochar may serve as a living place for pathogens, but it could also harm them. Here we summarize all the work done to date that links biochar to pathogens and provide the challlenges and opportunities that scientist and manufactures will have to overcome in order to increase the quality of the biochar.

Iron amendments minimize the first-flush release of pathogens from stormwater biofilters

People should be aware that swimming at the beach after a rainfall may cause illness due to the high concentration of bacteria in the water. However, if the right biofilters were widely implemented along the coast to treat stormwater, the risk of bacterial contamination after a rainfall would be drastically reduced. This is what we showed in this recent research paper – treating stormwater with biofilters containing iron filings can remove pathogens, especially at the beginning of a rainfall event (a.k.a. first flush). Protecting water is protecting life.

Nitrate removal uncertainty in stormwater control measures: Is the design or climate a culprit?

Stormwater Control Measures protect our natural water resources from pollutants such as nitrate, but their removal performance is unreliable. In this study, we analyzed the reason why nitrate removal is uncertain in SGI. We found out that, depending on the type of SGI, both the local climate and the design of the system may be the precursors of such uncertainty. Our results will assist stormwater managers in improving their water treatment based on the local climate and the available design features for that area/company/cost.

Biochar Selection for Escherichia coli Removal in Stormwater Biofilters

Not all biochar are the same. Here we explored how the main chemical structure properties of biochar influence the short- and long-term removal of pathogens from stormwater.

Conventional and amended bioretention soil media for targeted pollutant treatment: A critical review to guide the state of the practice

How can stormwater managers improve the removal of specific contaminants in bioretention systems? Our most recent article describes the decision-making process for selecting the finest amendment to improve contaminant removal efficiency in stormwater treatment systems. Our results are based on a data analysis linking the physicochemical interactions between amendments and contaminants.
