“…Recommended maintenance practices for DDBs include regular mowing to control weeds and prevent woody vegetation incursion, and sediment removal as needed to maintain proper drainage function (United States Department of Agriculture , Shammaa et al. ). However, DDBs often receive infrequent or inadequate maintenance, resulting in extended ponding of surface water when drainage is impeded by erosion, sedimentation, and debris accumulation (Lindsey et al.…”

Artificial aquatic habitats are ubiquitous in anthropogenic landscapes and highly susceptible to colonization by invasive plant species. Recent research into the ecology of infectious diseases indicates that the establishment of invasive plant species can trigger ecological cascades which alter the transmission dynamics of vector-borne pathogens that imperil human health. Here, we examined whether the presence or management of two invasive, emergent plants, cattails (Typha spp.) and phragmites (Phragmites australis), in stormwater dry detention basins (DDBs) alter the local distribution of vectors, avian hosts, or West Nile virus (WNV) transmission risk in an urban residential setting. Mosquitoes and birds were surveyed at 14 DDBs and paired adjacent residential sites. During the study period, emergent vegetation was mowed by site managers in three DDBs. In the absence of vegetation management, the overall abundance and species composition of both adult vectors and avian hosts differed between residential and DDB habitats; however, WNV entomological risk indices were equivalent. Communal bird roosts composed primarily of three species, European Starlings (Sturnus vulgaris), Red-winged Blackbirds (Agelaius phoeniceus), and Common Grackles (Quiscalus quiscula), representing a broad range of WNV reservoir competence, were observed at half (three out of six) of the DDBs containing unmanaged stands of phragmites; however, their presence was associated with a lower seasonal increase in vector infection rate. Conversely, mowing of emergent vegetation resulted in a significant and sustained increase in the abundance of WNV-infected vectors in DDBs and the increase in risk extended to adjacent residential sites. These findings indicate that management of invasive plants in DDBs during the growing season can increase, while presence of communal bird roosts can decrease, WNV transmission risk.

“…Today, many countries around the world have stormwater quality regulations and guidelines in place to curb the potential degradation of water resources by the different stormwater constituents, including phosphorus [8]. With these guidelines and regulations, a suite of stormwater treatment technologies such as grassed swales [9], constructed wetlands [10] and detention ponds [11,12] has also emerged. However, some of these systems have proven ineffective for the removal of dissolved nutrients and heavy metals [12][13][14].…”

Abstract:The investigation of electric arc furnace (EAF) steel slag as a viable add-on technology to existing stormwater systems for the removal of dissolved phosphorus (P) was extended to explore the effects of varying environmental and treatment system conditions. Parameters such as stormwater composition, P concentration, metal concentration, pH, temperature, slag mass and slag particle size were varied. Observations relating to the method of P removal via EAF slag were also carefully considered to explain removal mechanisms involved. Results demonstrated that, although physisorption contributed to P reduction, it was not the key P removal mechanism. Instead, precipitation was observed to be a key removal pathway as evidenced by the correlation between the loss of iron (Fe) from slag and the amount of P removed from solution. The reduced removal of P by slag in a copper-dominant stormwater solution was attributed to the formation of a stable complex formed by the interaction of copper with the slag via the ion-exchange surface model. The stability of this complex inhibits the loss of Fe from the EAF slag and, consequently, P removal by means of precipitation. In terms of the effect of changing environmental and treatment system conditions on the P removal process, stormwater composition, P concentration, metal concentration, pH, temperature, slag mass and slag particle size were found to significantly influence the effectiveness of EAF slag in removing P from a given stormwater system. It was also established that a number of combinations of these factors influence P uptake differently. OPEN ACCESSWater 2012, 4 322

“…The heavier sediment and buoyant litter derived from road surfaces may be filtered and settled out readily using Gross Pollutant Traps (GPT), whereas the removal of finegrained suspended solids requires stormwater to pass through a settling basin or a more elaborate treatment mechanism. Retention and detention ponds have been shown to be efficient in removing particulate-bound contaminants derived from roads, including trace metals and nutrients (Schueler and Helfrich 1988, Stanley 1996, Shammaa et al 2002, German and Svensson 2005. Pollutant reduction for retention and detention ponds is mainly through sedimentation with removal efficiency being dependent on the residence time and the proportion of the annual runoff volume effectively detained in the basin.…”

“…Investigations on different species of Lemnaceae (duckweed) grown in detention ponds found that a polyculture of Lemna minor and Spirodela polyrhiza was the most stable nutrient sink and removed the largest amount of phosphorus from stormwater detention ponds (Perniel et al 1998). The high performance of three Canadian ponds was attributed to large water storage volumes (CWP 2002b), whereas two dry ponds in the City of Edmonton, Canada had low TSS removal capacity owing to relatively short detention times (Shammaa et al 2002). Analysis of sediment deposited in thirteen small retention ponds was found to have highly, but viable TP content (510 to 2001 mg P per kg sediment) and that nutrients were predominantly fixed on the very fine sediment fraction (516 mm), which effected trap efficiency (Verstraeten and Poesen 2002).…”

Retention/detention basins are commonly used to remediate runoff from road surfaces in an attempt to remove contaminants before these materials enter adjacent waterways. However, the efficiency of such devices in removing contaminants is not well known, especially for Australian conditions. The efficiency of a retention/detention device adjacent to a major motorway in Sydney (Australia) was assessed for total suspended solids (TSS), a suite of trace metals (Cd, Cr, Cu, Fe, Mn, Ni, Pb, Zn), nutrients (TP, TKN, NO x , TN) and faecal coliforms. The mean removal efficiency of Cu, Pb, Mn and Zn was 23, 41, 43 and 41%, respectively, whereas the mean reduction in Cr, Fe and Ni concentrations was only 0, 3 and 1%, respectively. TSS in stormwater entering the retention/detention basin was highly variable resulting in large variations in removal efficiencies (range: 712 to 93%; mean: 40%). The mean removal efficiency of Kjeldahl nitrogen (TKN) and total nitrogen (TN) was high (56 and 28%, respectively) in contrast to total NO x and total phosphorus (TP) (742 and 75%, respectively). Faecal coliform was low to very low (55000 cfu/100 ml) and removal efficiency was 16 to 68%. Possible leaching of fine terrigenous particles from the gravel bed of the retention/detention basin may have contributed to the increase in Cr, Fe and Ni concentrations in effluent stormwater.
