“…We included the short one-year time series to the relevant seasonality groups, because the seasonality of distributed drinking water quality is quite often studied in time series with only one year of data [4,15,24]. Additionally, the seasonal patterns in the time series (Figure 2m–o) and in the seasonal indices (Figure 3m–o) were quite clear in all three cases.…”

We studied the seasonal variation of nitrite exposure in a drinking water distribution system (DWDS) with monochloramine disinfection in the Helsinki Metropolitan Area. In Finland, tap water is the main source of drinking water, and thus the nitrite in tap water increases nitrite exposure. Our data included both the obligatory monitoring and a sampling campaign data from a sampling campaign. Seasonality was evaluated by comparing a nitrite time series to temperature and by calculating the seasonal indices of the nitrite time series. The main drivers of nitrite seasonality were the temperature and the water age. We observed that with low water ages (median: 6.7 h) the highest nitrite exposure occurred during the summer months, and with higher water ages (median: 31 h) during the winter months. With the highest water age (190 h), nitrite concentrations were the lowest. At a low temperature, the high nitrite concentrations in the winter were caused by the decelerated ammonium oxidation. The dominant reaction at low water ages was ammonium oxidation into nitrite and, at high water ages, it was nitrite oxidation into nitrate. These results help to direct monitoring appropriately to gain exact knowledge of nitrite exposure. Also, possible future process changes and additional disinfection measures can be designed appropriately to minimize extra nitrite exposure.

“…Other metals (e.g., manganese) could become a problem by accumulating over time [11] needing special attention during treatment and transport of drinking water [47]. On the other hand the water treatment process itself may affect water quality, adding disinfection by products [48] or even affecting the bacterial antibiotic resistance [49]. Therefore prevention of eutrophication and diminishing surface water quality should have a preference over additional treatment [50].…”

Gravel pit lakes form when gravel deposits are excavated below the water table. We studied two fluvial gravel pit lakes called De Lange Vlieter (DLV Lake) and the Boschmolen Plas (BP Lake), in the Meuse River valley (The Netherlands). Water from the Meuse River is pumped only into the DLV Lake that is used for drinking water production. The mean values, the linear trends and seasonal patterns of time series data (2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014), of temperature, pH, nitrate, phosphate and sulphate were compared using one-way tests of variance and tests of differences. The effects of river water infiltration on DLV Lake are (1) a change in lake water temperature; (2) an increase in nitrate concentration (3) an increase in phosphate concentration and (4) a decrease in sulphate concentration. The effects of the air blowers in DLV Lake are (1) mixing of lake water; (2) decreasing pH in spring and summer (3) water oxygenation. Linear regression analysis shows an initially increasing nitrate concentration in DLV Lake that can be explained by the input of nitrate rich Meuse river water. Instead decreasing nitrate and phosphate concentrations in BP Lake and Meuse River reflect a diminished use of fertilizers. The gravel pit lake water temperature does not reflect climatic changes but the use of DLV Lake for artificial recharge has an impact on the seasonal and long-term trends in hydrochemistry. This poses a challenge to lake managers to find the right balance between reduction of eutrophication and accumulation of nutrients and sulphate.

“…Chlorine, a disinfectant for water treatment, which is extremely powerful, practical, and also cost-effective has been most widely used since the early twentieth. [1,2] .However, Natural Organic Matter (NOM) present in drinking water sources is a major problematic issue for disinfection, because it produces Disinfection by Products (DBPs) during chlorination [3,4]. A huge part of DBPs can potentially cause long-term adverse health effects.…”

“…Due to the tightening of water quality regulations, alternative treatment technologies have been proposed to improve the treatment of organic matters [9,10]. Nowadays, advanced treatment methods like membrane, ozone, nanoparticles have been applied [11,12] to 1 Yildiz Technical University, Department of Environmental Engineering, Istanbul, Turkey treat these polutants. Membrane technologies are shown as one of the most influential methods to purify NOM and DBP in many studies conducted in recent years [6,11].…”

Abstract-Along the Sakarya River, samples were taken from 2 different points; the first one was the Cifteler where the source of Sakarya River is located and the second one was Karasu area where Sakarya River ran to the Black Sea. Samples were collected during 2 different seasons; in winter and in summer in order to observe the seasonal effect. Trihalomethanes (THMs) and water quality parameters like Dissolved Organic Carbon (DOC), Ultraviolet Absorbance at 254 nm Wavelength (UV254), hardness, and conductivity values were examined. In order to remove the organic matter and THMs ozone and membrane process were performed. Good treatment efficiency was obtained with ozone and membrane process. The removal efficiencies of THMFP were found to be approximately 70%. Also, all parameters presented higher values in summer compared to winter. It was observed from the FT-IR analysis results that the aromatic and aliphatic functional groups in water changed after the treatment with ozone; and that peak values decreased more after the ozone+membrane treatment. TheSEM analysis showed that some compounds, such as Ca, Mg, and Fe, have been formed on the surface of the membrane after the purification through the membrane only, however these compounds decreased both in weight and size when membrane filtration is performed after a pre-ozonization.
