“…At the same time, technologies and approaches are being developed that can be used to reduce the unfavorable consequences of the human impact on nature, and to establish measures to protect natural resources and use them more efficiently [12]. The continuing and improved success of these technologies and approaches depends on research to improve our understanding of processes and phenomena occurring in the hydrosphere [13].Efficient management of water resources and, implicitly, of the quality of the water must find coherent solutions for pollution control, water use, as well as for land use [14]. The monitoring of surface waters should be based on a programmed process to collect samples and measure and record water parameters that will allow quality standards and the objectives proposed for the medium and long terms to be met.…”

The paper reviews the state of water quality in Ialomita River Basin (IRB), Romania, between 2007 and 2018 using the land use/land cover and basin-specific conditions effects on sediments and nutrients load. On-site monitoring was performed in two control sections of the Ialomita River, one in the upper part of the basin (near Targoviste city) and the second near the discharge into the Danube (downstream of Tandarei town). The statistical averages of water parameters for 10 years' monitoring in the control section that is close to the Ialomita River discharge in Danube were pH = 7.60 (range: 6.41-8.40), NH 4 -N = 1.20 mg/L (0.02-14.87), alkalinity = 4.12 mmol/L (1.34-6.27), NO 3 -N = 2.60 mg/L (0.08-17.30), PO 4 -P = 0.09 mg/L (0-0,31), dissolved oxygen (DO) = 8.87 mg/L (2.72-15.96), BOD 5 = 5.50 mg/L (0.01-74.71), suspended solids (TSS) = 508.32 mg/L (15.2-4457), total dissolved salts (TDS) = 733.69 mg/L (455.2-1053), and river discharge = 38.60 m 3 /s (8. . Expected mean concentration and soil and water assessment tool (SWAT) modeling have been employed in the GIS environment to extend the approach to large spatial patterns within the basin. The estimated average specific emission on the total area for nitrogen was 3.2 kg N/ha, and 0.3 kg P/ha for phosphorus highly influenced by the agricultural activities. The results are useful to raise awareness regarding water-quality degradation and the need to stop and even reverse such trends for local and national sustainable development.Water 2020, 12, 735 2 of 19 water [2]. The discharge of toxic substances, the contamination of groundwater, and the atmospheric transport of nutrients over long distances leading to eutrophication of surface waters, are some of the important processes responsible for the degradation of water quality [3].Massive pollution with organic compounds leads to increased biological oxygen demand and hypoxia, which is often accompanied by severe pathogenic contamination [4]. Eutrophication resulting from the enrichment with nutrients originating from various sources and in particular from agriculture and agro-industrial environment strongly influences the biosphere [5,6]. The over-application of fertilizers damages the ecosystems on large spaces, including soil, water and underground aquifer layers [7]. The main problems associated with intensive agriculture are salinization, nitrification, pesticide contamination and excessive erosion that produce high concentrations of colloids in flowing waters [8].Significant emissions of atmospheric pollutants and long-range transport have affected large areas, while droplets formed in the atmosphere through the combination of water with the gases produced by burning fossil fuels cause acid rain that leads to the acidification of surface waters, especially of lakes [9].Society uses natural resources in a steadily increasing rate. Human influence on nature may cause adverse consequences leading to the disturbance of the natural balance [10,11]. At the same time, technologies and approaches are being developed...

“…Although the Spring Lake watershed is larger than this threshold, the alternative method (export coefficient) was found deficient because it does not take into account precipitation or impervious surface area (US EPA 2001), and the loading rate is derived from export coefficient tables, which were not available for Michigan or other regions similar to the Spring Lake watershed. In addition, the PLOAD simple method has been successfully applied in watershed basins even larger than Spring Lake (Syed and Jodoin 2006;Goodwin 2007). We adopted the approach used by Syed and Jodoin (2006), who applied the PLOAD simple method to sub-basins in the Lake St. Clair (MI) drainage area; both watersheds are located in Michigan's lower peninsula with similar degrees of latitude, landscapes, lithologies (glacial modification of regolith), and land use/cover types.…”

“…PLOAD does not use hydrologic soil group data within the model to adjust for rainfall-runoff; curve numbers were derived from existing hydrologic soil group and land use/cover data to determine a rainfall-runoff coefficient for each subbasin. Utilizing these curve numbers with the long-term precipitation data gave more accurate rainfall-runoff data per sub-basin than using the same average yearly rainfall value for the entire watershed, with no regard to the reduction of runoff because of storage and initial abstraction (i.e., interception, infiltration, depression storage, and antecedent soil moisture) (Syed and Jodoin 2006).…”

Stormwater runoff to an impaired lake: impacts and solutions

Stormwater runoff can represent a significant source of pollutants to downstream water bodies. An integrated assessment was conducted for the Spring Lake watershed in western Michigan because of concerns that increased impervious land cover in the watershed, especially in sub-basins adjacent to Spring Lake, would result in greater stormwater runoff and pollutant loads. Spring Lake has a history of high total phosphorus (TP) concentrations and cyanobacterial blooms. An alum treatment, paid for by an assessment, was applied to Spring Lake in 2005 to control internal phosphorus loading; hence, there was an economic incentive for stakeholders to limit new phosphorus from entering the lake, which otherwise would reduce the long-term efficacy of the alum treatment. This study provides a novel six-step process that identifies priority areas and optimally reduces nonpoint sources of pollution. We identified a suite of best management practices to be placed in the watershed, assessed their optimal locations based on pollutant sources, and modeled the degree to which their implementation would reduce TP and total suspended solids. Application of the modeled best management practices (BMPs) resulted in a 15 % reduction in TP load and a 17 % reduction in total suspended solid load. Reductions were not uniform throughout the watershed, with the greatest reductions closest to Spring Lake. We also developed a flow chart for BMP selection, which may be transferable to other watersheds with similar issues.
