	abstract = {The manureshed concept was developed to address the uneven distribution of manure nutrients in and around livestock operations and recycle manure in areas where crops require nutrients. The implementation of manureshed concept can improve manure nutrient use efficiency and reduce manure nutrient loss to downstream waterbodies. The study aims to quantify the water quality benefits of implementing manureshed concept for nutrient management in the Susquehanna River Basin (SRB) through scenario-based analyses using the Soil and Water Assessment Tool (SWAT). The specific objectives include (i) formulation of manureshed concept-based nutrient redistribution scenarios for the SRB, (ii) evaluation of water quality impacts of manureshed concept-based manure management in SRB both at outlet draining to the Chesapeake Bay and at local streams. Six manureshed concept-based manure redistribution scenarios were formulated for the SRB, which included (i) Crop N demand-based Restricted Manure Transport (BL, Baseline), (ii) Crop N demand-based Manure Balanced (N-MB; manure redistributed to nearby nutrient demand areas), (iii) Crop N demand-based Suitable Soil Transport (N-SST; Manure applied only in suitable areas), (iv) Crop P demand-based Restricted Manure Transport (P-RT), (v) Crop P demand-based Manure Balanced (P-MB), and (vi) Crop P demand-based Suitable Soil Transport (P-SST). Scenario-based analyses demonstrated that the crop P demand-based manure application significantly reduced manure nutrient loss; the P-MB scenario simulated 3\% TN and 25\% TP loss reductions at the SRB outlet compared to the BL scenario. The crop N demand-based manure application simulated a 3-5\% reduction in nutrient loading at the watershed outlet compared to baseline; the N-SST scenario simulated 3\% TN and 4\% TP loss reductions at the SRB outlet. The study results are promising and encourage stakeholders to implement manureshed concept-based manure management in SRB.},

	abstract = {<p>We developed a cost-based methodology to assess the value of forested watersheds to improve water quality in public water supplies. The developed methodology is applicable to other source watersheds to determine ecosystem services for water quality. We assess the value of forest land for source water mitigation of total organic carbon (TOC) through the use of linked watershed and reservoir simulation models and cost-based valuation economics. Watershed modeling results indicated that expected urbanization will increase TOC loads to Converse Reservoir (Mobile, AL).\&nbsp; Reservoir model results indicated that future median TOC concentrations increased by 1.1 mg\&middot;L-1 between 1992 and 2020 at the source water intake. Depending upon dynamic reservoir TOC concentrations, additional drinking water treatment with powdered activated carbon (PAC) often is necessary between May and October to comply with Safe Drinking Water Act regulations. The cost for additional treatment was calculated using minimum and maximum volume treated with simulated TOC concentrations at the source water intake. Daily simulated TOC concentrations for the base scenario using 1992 land cover (3\% urban) were compared with simulated TOC concentrations following forest to urban land conversion predicted in the watershed by 2020 (22\% urban).\&nbsp; The daily cost for additional drinking water treatment with PAC was calculated if simulated TOC concentrations exceeded 2.7 mg\&middot;L-1. The mean increase in daily treatment costs between base and future scenarios ranged from $91 to $95 per km2 per day for forest land water purification ecosystem services.</p>
