“…With less than 1 mg/L in samples collected from groundwater monitoring wells at six study sites in Iowa, roadside ditches were shown to have typical reduced NO 3 -N concentrations in groundwater for watershed-scale treatment of NPS pollution [26]. Metal concentrations in the present study were generally higher than those found in other studies (Tables 1 and 2; e.g., [11,18]). While Al and Mn concentrations have not been extensively examined with regard to roadside ditch water quality, Cu, Fe, and Zn have often been studied in surface runoff from roadside ditches in many studies (e.g., [13,17,[27][28][29].…”

“…The researchers explained that flow rate added high variability to the performance of the swales but found that nutrient removal generally appeared to decrease along the length of the swale. An evaluation of roadside filter strips in North Carolina also revealed considerable reductions in NO 3 -N, NO 2 -N, metal, and total suspended solids (TSS) concentrations [17,18].…”

Roadside ditches play an important role in the quantity and quality of receiving waters. Very little, however, is known about the fate and transport of nutrients and trace metals in roadside ditches, especially their leaching to shallow groundwater. This study sought to document selected water quality constituent levels in infiltrated water (i.e., leachate) in roadside ditches maintained with permanent vegetation. Leachate sampling wells were installed in four roadside ditches, and water samples were collected from the wells following major rainfall events during the years 2016 and 2017. The samples were analyzed for nutrient and metal concentrations. Results indicated that nutrient concentrations in the water samples range from 0.00600 to 0.0107 mg/L for orthophosphate (PO 4 -P), 0.00500 to 6.80 mg/L for nitrate (NO 3 -N), 0 to 0.007 mg/L for nitrite (NO 2 -N), and 0.0100 to 314 mg/L for chloride (Cl − ). Concentrations of the metals examined varied between 0.0100 and 104 mg/L in water samples. While there was no specific pattern in both nutrient and metal concentrations when roadside ditches maintained with cool season grass were compared to those of warm season grass ditches, results suggest that grass types will likely affect differently uptake of nutrients and metals in the ditches.

“…Bridge runoff can increase concentrations of PO 4 -P and TSS if stormwater control measures are not installed (Winston et al, 2015). Our results found that, in the canal with water flowing under a bridge crossing (Segment 1), there was no greater effect on NO 3 -N and PO 4 -P concentrations than on the transportation of solids (Tables 2 and 3).…”

The Lower Rio Grande Valley (LRGV) of South Texas contains an extensive stormwater conveyance canal system supported by culverts and crossings. This project examined representative canal segments in this system to determine the effects of stormwater conveyance structures and crossings as well as surrounding land use on water quality and the ability of the canal system to meet Texas freshwater surface water standards. Data collected for 18 physiochemical and nutrient parameters was used to generate summary statistics and perform analyses of variance and correlation analyses. The results of the analyses suggested that conveyance structures and crossings and land use significantly affected 12-13 water quality parameters. Box culverts in the canal system are more likely to affect water quality than bridge crossings or culverts placed above and below the water surface. Agricultural and residential land, roads, and trees and bushes planted on the canal boundaries effected water quality similarly, whereas the maintained, vegetated edges of canals had the greatest influences on water quality. Overall, water quality in the LRGV canal system meets federal and state standards and aquatic life criteria. The findings of our water quality survey provide significant information that could assist with municipal, county, and regional environmental compliance management.

“…Median effluent concentrations of TN, TP, and TSS were low, with values of 0.87, 0.05, and 1 mg/L, respectively. The median effluent TN concentration is marginally higher than typical for SCMs employing biologically-based treatment mechanisms, such as bioretention, while the TP and TSS median effluent concentrations were lower than conventional SCMs reported in the literature (Winston et al 2015). NO 2 , TAN, and OP concentrations were not significantly different after stormwater passed through the treatment train.…”

Water quality performance of a permeable pavement and stormwater harvesting treatment train stormwater control measure

Stormwater runoff from urban development causes undesired impacts to surface waters, including discharge of pollutants, erosion, and loss of habitat. A treatment train consisting of permeable interlocking concrete pavement and underground stormwater harvesting was monitored to quantify water quality improvements. The permeable pavement provided primary treatment and the cistern contributed to final polishing of total suspended solids (TSS) and turbidity concentrations (>96%) and loads (99.5% for TSS). Because of this, >40% reduction of sediment-bound nutrient forms and total nitrogen was observed. Nitrate reduction (>70%) appeared to be related to an anaerobic zone in water stored in the scarified soil beneath the permeable pavement, allowing denitrification to occur. Sequestration of copper, lead, and zinc occurred during the first 5 months of monitoring, with leaching observed during the second half of the monitoring period. This was potentially caused by a decrease in pH within the cistern or residual chloride from deicing salt causing de-sorption of metals from accumulated sediment. Pollutant loading followed the same trends as pollutant concentrations, with load reduction improved vis-à-vis concentrations because of the 27% runoff reduction provided by the treatment train. This study has shown that permeable pavement can serve as an effective pretreatment for stormwater harvesting schemes.
