Mobility of polypropylene microplastics in stormwater biofilters under freeze-thaw cycles

Autor: Vera S. Koutnik, Annesh Borthakur, Jamie Leonard, Sarah Alkidim, Hatice Ceylan Koydemir, Derek Tseng, Aydogan Ozcan, Sujith Ravi, Sanjay K Mohanty

Publikováno v: Journal of Hazardous Materials Letters, Vol 3, Iss , Pp 100048- (2022)

Stormwater biofilters naturally experience dry-wet and freeze-thaw cycles, which could remobilize deposited particulate pollutants including microplastics. Yet, the effect of these natural weathering conditions on the mobility of deposited microplast

Dry-wet and freeze-thaw cycles enhance PFOA leaching from subsurface soils

Autor: Annesh Borthakur, Patience Olsen, Gregory P. Dooley, Brian K. Cranmer, Unnati Rao, Eric M.V. Hoek, Jens Blotevogel, Shaily Mahendra, Sanjay K. Mohanty

Publikováno v: Journal of Hazardous Materials Letters, Vol 2, Iss , Pp 100029- (2021)

Subsurface soil naturally experiences dry-wet and freeze-thaw cycles, which could affect the leaching of previously adsorbed pollutants. A slow release of poly- and perfluoroalkyl substances (PFAS) from impacted subsurface soil may serve as a long-te

Investigation of Soil Suction Characteristics Induced by the Degradation of Organic Matter

Autor: Annesh Borthakur, Anant Aishwarya Dubey, K. Ravi

Publikováno v: Geotechnical and Geological Engineering. 40:2371-2378

Total soil suction is considered to be the accumulative influence of matric and osmotic suction, assuming that the soil is biologically inert. However, there are several biological activities occurring in soil media, which result in the degradation a

Natural aging of expanded shale, clay, and slate (ESCS) amendment with heavy metals in stormwater increases its antibacterial properties: Implications on biofilter design

Autor: Annesh Borthakur, Kristida L. Chhour, Hannah L. Gayle, Samantha R. Prehn, Michael K. Stenstrom, Sanjay K. Mohanty

Publikováno v: Journal of hazardous materials. 429

Aging is often expected to decrease the pathogen removal capacity of media because of exhaustion of attachment sites by adsorption of co-contaminants and dissolved organics. In contrast, the adsorption of metals naturally present in stormwater during

Perfluoroalkyl acids on suspended particles: Significant transport pathways in surface runoff, surface waters, and subsurface soils

Autor: Sanjay K. Mohanty, Shaily Mahendra, David T. Adamson, Jens Blotevogel, Meng Wang, Katia Ascencio, Meng He, Annesh Borthakur

Publikováno v: Journal of hazardous materials. 417

Eroded particles from the source zone could transport a high concentration of perfluoroalkyl acids (PFAAs) to sediments and water bodies. Yet, the contribution of suspended particles has not been systematically reviewed. Analyzing reported studies, w

Biochar Selection for Escherichia coli Removal in Stormwater Biofilters

Autor: Yeyang Zu, Ed A. Matthiesen, Michael K. Stenstrom, Renan Valenca, Annesh Borthakur, Sanjay K. Mohanty

Publikováno v: Journal of Environmental Engineering. 147

Biochar’s capacity to remove pathogens from stormwater can vary by orders of magnitude, which makes it challenging for stormwater managers to select specific biochar from suppliers. In this...
