Summary: Stormwater wet ponds (SWPs) are important nitrogen sinks that have seasonal variation in nitrogen cycling, affecting pond nitrogen removal. Sediments in SWPs generally function as total nitrogen (TN) sinks during nitrate-enriched conditions, but the fate of nitrate varies based on factors such as water temperature, dissolved organic nitrogen concentrations, and sediment oxygen uptake. This study suggests that coastal stormwater ponds may host reduced conditions that promote nitrate retention over denitrification, highlighting the need for further research on the fate of retained nitrate in SWP sediments and its impact on downstream water quality.

Summary: This study investigated the distribution of stormwater ponds and the dissolved nutrient concentrations in these ponds in relation to different land uses in a rapidly developing suburban watershed. The results showed that different land uses had varying impacts on water quality, with more intense chemical use related to higher nutrient concentrations and lower water clarity. These findings highlight the importance of considering both surface runoff and management practices in understanding nutrient concentrations in stormwater ponds.

Summary: The study evaluated nutrient and metals concentrations in the soil water of five different GSI systems, finding that copper and zinc concentrations were impacted by GSI age, while phosphorus concentrations were influenced by multiple factors including age and sources. Changes to the soil mix design may be necessary to reduce high levels of phosphorus in soil water.

Summary: Cover cropping is a cost-effective practice to reduce nutrient losses in cropland. In Pennsylvania's Chesapeake Bay watershed, cover crops were used on 39% of the annual crop area, higher than the US average. However, commodity cover crops are not currently included in the Chesapeake Bay Model for nutrient reduction credits.

Summary: Urban gardens and farms contribute significantly to nitrogen and phosphorus export in stormwater runoff, due to high compost inputs and low nutrient use efficiencies. The contribution of gardens to nutrient export depends on retention efficiency values, with high efficiency minimizing their impact. Understanding the long-term fate of excess nutrients in urban landscapes is crucial.

Summary: Urban gardens and farms using compost as a nutrient source can contribute significantly to urban nutrient budgets through stormwater runoff. The study finds that gardens and farms, although occupying a small fraction of land area, account for a large proportion of nitrogen and phosphorus inputs to urban landscapes. The significance of their contribution depends on compost inputs and nutrient retention efficiency, highlighting the importance of understanding the fate of excess nutrients on urban landscapes.

Summary: This study investigated the relationship between integrated landscape patterns and stream water quality in different seasons in ten Chinese subtropical catchments from 2010 to 2017. The study found that nitrogen and phosphorus levels in stream water varied significantly between the fallow season and the rice-growing season, and were influenced by different landscape configuration factors in each season. In the rainy season, stream water nitrogen and phosphorus levels were more likely to be affected by landscape composition, while in the dry fallow season, landscape configuration played a more significant role in determining nitrogen and phosphorus levels.

Summary: Nutrient loss in surface runoff from hill country catchments is typically generated from small areas and over short time periods. This study compared nutrient and sediment losses in surface runoff on two hill country sub-catchments with contrasting soil types. The results highlight the potential benefit of strategically placing cattle feed supplements on soils less prone to surface runoff to improve freshwater outcomes.

Summary: This study used dendrogeomorphology to measure long-term streambank erosion, floodplain deposition, and sediment fluxes in streams across the U.S. Mid-Atlantic. The results showed that geomorphic change and resulting sediment and nutrient fluxes were influenced by land use and watershed characteristics. The findings provide important insights into the balance of erosion and deposition in disturbed landscapes and the impact of geomorphic change on stream water quality and carbon sequestration.

Summary: This study used a sediment budget approach to determine the sources, storage, and delivery of sediment in the Smith Creek watershed. The results showed that streambanks and pastures were major sources of sediment. The study also indicated that the storage of sediment in the watershed may have been underestimated due to unaccounted geomorphic features. The findings provide a framework for managers to address the sediment problem in Smith Creek and similar tributaries to the Chesapeake Bay.

Summary: This study evaluated the effect of alternative filtering materials and bed aeration on the retention of nutrients and fecal bacteria in woodchip bedded stand-off pads for cows. The results showed that the alternative biofilters were more efficient in removing COD, SS, TN, and NO3-N, while conventional biofilters were more efficient for PO4-P removal. Aeration did not have a significant effect under the tested temperature conditions.

Summary: This study evaluates the performance of ozonation and adsorption as in-series processes compared to standalone processes for the removal of Contaminants of Emerging Concern (CECs) in drinking water. The combination of both processes proves to be more effective than adsorption and ozonation alone. Ozonation improves the adsorption performance of poorly-oxidizable CECs but worsens that of well-oxidizable compounds. This research highlights the importance of considering both processes in the removal of CECs in drinking water treatment plants.

Summary: The exacerbation of global warming, extreme weather events, and rapid urbanization have led to increased flooding in urban areas. China has adopted sponge city as an efficient means of preventing and controlling urban floods. Using a SWMM-FVCOM model, the hydrological reduction and control effect of sponge city construction (SPCC) within a university campus were evaluated. The study found that implementing SPCC effectively mitigates surface runoff and reduces the severity of urban flooding. However, the efficacy of runoff control decreases with longer rainfall return periods.
