This study aimed to evaluate the wastewater generation in the south of Binh Duong province (including Di An, Thuan An, Tan Uyen, Ben Cat districts and Thu Dau Mot city) where is many development activities were undertaken as well as the risk of water pollution. By survey, data collection, and GIS, main pollutant loads (BOD, COD, SS, total N and total P) generated from main waste sources (domestic, industry, and livestock) were estimated and forecasted until 2030. The results showed that the amount of pollutant load in 2016 was about 105,273.6 ton/year, most of which came from domestic wastewater (about 60%). Di An and Thuan An districts generated the highest pollutant load in the study area, corresponding to 5.4 ton/ha.year and 2.8 ton/ ha.year. COD and BOD occupied a high proportion of pollutant parameters, which were 0.5 ton/ha.year and 0.26 ton/ha.year, respectively. To estimate the pollutant load in the future, two wastewater treatment scenarios were taken into the consideration: as similar as the current status (KB H) and according to A standard (KB A). By 2025, the total pollutant load would increase 2.1 times for KB H and 1.2 times for KB A. The corresponding figures for 2030 would be 3.1 and 2.0 times, respectively, indicating many pressures on the water quality. Accordingly, it is necessary to continue studying and evaluating the capacity of water sources for receiving wastewater, to the create basis for water quality management in particular and environmental management in general.

The inflow of pollutant load from urban areas and the stagnation of water due to sea water intrusion cause the deterioration of river water quality in tidal zone. In order to improve water quality, various measures such as the reduction of pollutant load by sewage systems, discharge control from sewage treatment plants considering river flow, nutrient removal by aquatic plants, and the dredging of bottom sediments have been examined. The choice of these measures depends on the situation of the river environment and finances. In this study, a field survey was carried out in a typical urban river basin, first. Secondly, on the basis of this survey, a mathematical model was formed to simulate flow and water quality. Several purification alternatives designed for the investigated river basin were comparatively evaluated from the viewpoint of the effect of water quality improvement and their cost. Finally, they were prioritized. Through this case study, a planning process of river water quality management was shown.

In traditional waste load allocation (WLA) decision making, water quality-related constraints must be satisfied. Fuzzy models, however, can be useful for policy makers to make the most reasonable decisions in an ambiguous environment, considering various surrounding environments. We developed a fuzzy WLA model that optimizes the satisfaction level by using fuzzy membership functions and minimizes the water quality management cost for policy decision makers considering given environmental and socioeconomic conditions. The fuzzy optimization problem was formulated using a max–min operator. The fuzzy WLA model was applied to the Yeongsan River basin, which is located in the southwestern part of the Korean Peninsula and Korean TMDLs were applied. The results of the fuzzy model show that the pollutant load reduction should be increased in the Gwangju 1 and Gwangju 2 wastewater treatment plants (WWTPs) and in subcatchments with high pollutant load. In particular, it is necessary to perform advanced wastewater treatment to decrease the load of 932 kg ultimate biochemical oxygen demand (BODu)/day in the large-capacity Gwangju 1 WWTP and reduce the BODu emission concentration from 4.3 to 2.7 mg/L during the low-flow season. The satisfaction level of the fuzzy model is a relatively high at 0.81.

This study evaluated the effectiveness of soils with different textures and thickness to treat BOD, N and P eluted from household septic effluent. The assessments were accomplished by leaching undisturbed soil monoliths of 30, 45 and 60 cm thickness and 25 cm in diameter, representing the four different textural groups and hydraulic loadings recommended by the Kentucky Health Department, with domestic wastewater effluent collected regularly from a household septic system. Effluent concentrations were monitored daily over a 15 d period for biochemical oxygen demand (BOD), total-N, NH4–N, NO3–N and total-P concentrations. The results of the study indicate an alarming frequency of failure to comply with EPA criteria for BOD, total-N and NH4–N concentrations when using a 30 cm vertical separation distance between the bottom of the drain field and a limiting soil interface. The treatment performance was particularly poor in coarse-textured soils, apparently due to insufficient reactive surface area. Although biomat development over time is expected to improve the treatment for some of these parameters, the high influent levels of BOD pose great concerns for surface and groundwater contamination during the early stages of operation. Fine-textured soils generally provided better treatment efficiency and more consistent compliance with EPA standards for BOD, total-N, NH4–N and total-P, as well as greater nitrification/denitrification potential. Treatment efficiency and compliance usually improved with increasing soil depth, with the 60 cm thickness providing the most consistent performance and compliance with MDL requirements. Considering that increasing soil thickness requirements may be impractical in many marginal soils, complementary or alternative treatment technologies should be adopted to improve treatment efficiency and prevent further deterioration of the quality of water resources.

Abstract Cibeureum watershed is a river located on the border of Cimahi City and Bandung City and empties into the Citarum River. One of the Cibeureum watersheds is from the agriculture sector. Rice fields and gardens in South Cimahi are contributors to pollution in the Cibeureum Sub-watershed. Research on the assessment of pollution load capacity in the Cibeureum Sub-watershed to learn to understand and analyze the burden of the agricultural sector. In addition, the study of the capacity of pollution load in the Cibeureum River has never been carried out, so it is necessary to conduct a study of capacity. Calculation of pollutant load requires data on the area of paddy fields and gardens, emission factors and the number of planting days. Cibeureum watershed is a heavily polluted river after being calculated using pollutant methods with 11.09 results. Pollutant load of Cibeureum Sub-watershed agriculture sector in 2018 is 0.01689 kg/day BOD, 0.001501 kg/day Total-N, 0.0008 kg /day Total-P, and 0.000003 kg /day TSS. Pollutant load for Cibeureum Sub-watershed agriculture sector in 2018 is 0.103377 kg/day BOD, 0.009542 kg/day Total-N, 0.0048 kg/day Total-P, and 0.00508kg/day TSS. Pollutant load generated from the agricultural sector in the year of allocation will not be excluded from the budget for the development of Cimahi City Regulation Number 4 of 2013 concerning Spatial Planning and Cimahi City Areas for 2012-2032. Keywords: Pollutant Load, Agriculture Sector, Cibeureum Sub-watershed, Indonesia  AbstrakSub DAS Cibeureum merupakan sungai yang berada di perbatasan Kota Cimahi dan Kota Bandung dan bermuara ke Sungai Citarum.

We investigated the relationship between land use parameters and FRAGSTATS-based landscape metrics (Edge Density, Patch Density, Mean Shape Index, Mean Euclidean Nearest Neighbour Index, Contagion, Patch Richness Density and Shannon's Diversity Index) and nutrient/organic-matter-based water quality indicators (BOD7 and CODKMnO4 values, total-N and total-P concentrations in water) in 24 catchments with various land use patterns in Estonia, using the CORINE Land Cover Map (1:100 000). Multiple regression analysis showed that, for BOD7, total-N and total-P, the most important predictor was the proportion of urban areas, but landscape metrics also had a significant relationship with water quality. Mean Shape Index and Contagion were the most important predictors for CODKMnO4. The knowledge that land use and landscape configuration impact water quality can be used in establishing and implementing water management plans in Europe.

The lack of domestic wastewater management services in the Cibabat River Basin has resulted in the Cibabat River being a place to collect domestic wastewater. This of course can reduce water quality  as well as reduce the function of the river itself.  The Cibabat river is known to be a sub-watershed of the Citarum River with a surface   area of  1,855 km2. Activities in the Cibabat watershed  contribute  to the pollution load that  causes the water quality of the Cibabat River to decline, which of course has an impact on the decrease  in the quality of the river and increase  in the polluting  load that the river will receive. The research method uses the calculation of the pollutant  load based on Permen LH 115/2003. The data used are  secondary data from DLH Cimahi City, which  conducted a water quality analysis at three points during  three different seasons in 2019. One of the steps to overcome and control the pollution that occurs is to determine the actual pollutant load so that it can easily determine the application of effective technology  for controlling river water pollution  in the Cibabat River at theCimahi City.

Water quality modeling is increasingly recognized as a useful tool for obtaining valuable information for optimal water quality management. In this study, the free software QUAL2Kw was used to evaluate the impacts of agricultural nitrogen (N) excess on river nitrate (NO3-N) concentrations. We explored the possibility to use QUAL2Kw in order to back calculate the exchange of water and N from the groundwater to the Oglio River, northern Italy, which drains a heavily irrigated and fertilized agricultural land. Along the river course water monitoring activities carried out in the dry, summer period revealed steep increases of NO3-N in different sectors, by up to 2 orders of magnitude, not explained by any significant point inputs. Such increases suggest the occurrence of large water exchange with nitrate-polluted groundwater and diffuse inputs. In turn, groundwater pollution is due to high N excess in the watershed (~200 kg N ha-1 yr-1), flood-based irrigation techniques and soil permeability. The QUAL2Kw model was calibrated using the average of 2 years' data collected in winter 2010 and 2011 and validated using the data of winter 2012. To minimize the error between simulation results and measured data, the constants of inorganic suspended solid (ISS), ammonium (NH4-N), nitrate and organic N were calibrated. The calibration and validation results showed a good correspondence between the calculated and measured values for most of water-quality variables. QUAL2Kw was then run separately with three years' summer data (2009, 2010 and 2011), and large gaps were found between the measured and predicted values of discharge, electrical conductivity, NO3-N and total N. Such gaps are discussed in terms of river-groundwater interactions, limited to the summer period and following irrigation by flooding, rise of the groundwater table and vertical transport of N. The gaps allowed to back calculate the volumes of water and the amount of N exchanged. The total load of NO3-N entering into the river from groundwater was estimated in 25.17, 25.63 and 29.89 ton per day for NO3-N in 2009, 2010 and 2011, respectively. Similar results were obtained in another study based on mass balance of N isotopes. The combination of experimental and QUAL2Kw modelled data proved to be a simple, low cost but effective tool in the estimation of NO3-N exchange between the surface and groundwater.

The effluent from the combined household wastewater treatment facilities used in unsewered areas of Japan is generally high in nitrogen (N) and phosphorus (P). In Japan, environmental quality standards for zinc (Zn) pollution were enacted recently because of the toxicity of Zn to aquatic ecosystems. In 2004 a fallow paddy field at the Koibuchi College of Agriculture and Nutrition was converted into a surface-water-flow constructed wetland (500 m2) to clean the effluent from the combined household wastewater treatment facility of a dormitory (100 residents) before discharge to a pond. We evaluated N and P removal efficiencies and the fate of soluble Zn in the wetland from April 2006 to March 2007. Wetland influent contained an average of 18.3 mg L−1 total N and 1.86 mg L−1 total P. In the effluent from the wetland, average total N concentration was 10.3 mg L−1 and average total P was 0.90 mg L−1. Average removal rates were 0.37 g m−2 d−1 for total N and 0.050 g m−2 d−1 for total P (percentage removal rates of 40% and 48%, respectively). Soluble Zn concentration decreased from 0.041 in the influent to 0.023 mg L−1 after passing through the wetland. The average Zn removal rate during the year was 0.0007 g m−2 d−1 (percentage removal rate 37%).

The Cai stream is a wastewater receiving stream from industrial zones in Tan Uyen town (Binh Duong province), which is facing to pollution risks, requiring appropriate management measures, especially in the context of socio-economic development. Accordingly, the study aimed to assess the current status and to forecast its water quality until 2020. By sampling, analysis, and water quality index (WQI), the results show that water quality in dry season of 2017 ranged from poor to medium level (WQI 23-79) and tended to increase towards the downstream. Some streams being concerns in terms of water quality were the Cho stream (WQI 18 - 31), the Cai stream flowing through VSIP II (WQI 26 - 35), the Tre stream flowing through waste water treatment plants of VSIP II (WQI = 40)... It could be explained by high turbidity, TSS and NH4-N concentrations. Water quality in 2020 was simulated by the Mike 11 model and demonstrated on maps using GIS. Simulation results show an increase in COD, BOD, TSS, total nitrogen, and total phosphorus concentrations in relation to local socio-economic development plans, especially COD and TSS (the highest concentrations would be 48 mg/L and 205 mg/L, respectively). In some areas, there is a clear increase in pollution levels, such as the Tre stream, the confluence of the Tre and the Cai streams, downstream of the Cai stream, the Vinh Lai stream, and the Cho stream. Research results could be an important basis for environmental management in general, water quality management in particular, contributing to sustainable development goals of the local.
