Comparative Nitrogen and Pesticide Removal with Sorption Media In Linear Ditch for Groundwater and Stormwater Treatment

Performance of two types of biosorption activated medium (BAM), woodchip and Bold & Gold (B&G) filter material, were compared in a laboratory column study for nitrogen removal. Both performed well under a saturated condition. However, field construction along a highway ditch could not achieve saturated conditions. Field Sampling data were acquired for the comparison with the lab column study results. The performance of B&G in the field is consistent with the column study, but woodchip performs unsatisfactory for the removal of nitrogen in the field. The reasons involve media characteristics and saturation differences. In addition, the cost-benefit analysis was assessed based on both lab and field removal performance, B&G showed great potential when it was applied in the field while woodchip has negative nitrogen removal due to significant ammonia generation, plus, over 50% decomposition of woodchip was observed within one year of field operation.
