The aim of this paper was to evaluate the groundwater pollution in an endoreic basin in southern Italy. The aquifer circulation was carried out on two different levels: a shallow groundwater, with a water table of about 10 m, and a deep groundwater in a karst aquifer, with a water table of 140–190 m. Reclaimed municipal wastewater and superficial water collected in the catchment area were both drained in a swallow hole linked with the deep groundwater. The agricultural practice conducted in the endoreic basin produced an excess of nitrate in the soil. Nitrate was subsequently washed out and displaced in the groundwater. With regard to the EU Drinking Water Directive (98/83/EC), the research activity conducted during 2003 showed the absence of pollution in the deep groundwater used for drinking water supply. The shallow groundwater, instead, was strongly influenced by agricultural and pasture activities, with detectable levels of nitrates and bacteria. In order to reduce the load of pollution entering the swallow hole and then in the deep groundwater, the realisation of a constructed wetland plant was proposed to improve the quality of reclaimed wastewater, as well as to pursue the wastewater reuse in agriculture.

Background. Cancer is a significant disease burden in the world. Many studies showed that heavy metals or their compounds had connection with cancer. But the data conflicting about the relationship of manganese (Mn) to cancer are not enough. In this paper, the relationship was discussed between Mn concentrations in drinking water for rural residents and incidence and mortality caused by malignant tumors in Huai’an city.Methods. A total of 158 water samples from 28 villages of 14 towns were, respectively, collected during periods of high flow and low flow in 3 counties of Huai’an city, along Chinese Huai’he River. The samples of deep groundwater, shallow groundwater, and surface water were simultaneously collected in all selected villages. Mn concentrations in all water samples were determined by inductively coupled plasma-mass spectrometry (ICP-MS 7500a). The correlation analysis was used to study the relationship between the Mn concentration and cancer incidence and mortality.Results. Mn concentrations detectable rate was 100% in all water samples. The mean concentration was 452.32 μg/L ± 507.76 μg/L. There was significant difference between the high flow period and low flow period (t=-5.23,P<0.05) and also among deep groundwater, shallow groundwater, and surface water (F=5.02,P<0.05). The ratio of superscale of Mn was 75.32%. There was significant difference of Mn level between samples in the high flow period and low flow period (χ2=45.62, P<0.05) and also among deep groundwater, shallow groundwater, and surface water (χ2=10.66,P<0.05). And also we found that, during the low flow period, Mn concentration has positive correlation with cancer incidence and mortality; for a 1 μg/L increase in Mn concentration, there was a corresponding increase of 0.45/100000 new cancer cases and 0.35/100000 cancer deaths (P<0.05).Conclusions. In Huai’an city, the mean concentration of Mn in drinking water was very high. Mn concentration correlated with cancer incidence and mortality.

&lt;p&gt;Having drinking water is one of the sustainable development goals (SDG no. 6) that is not always easy to ensure, especially in countries like Spain or arid regions marked by water deficit. The reuse of treated water should be considered when planning water resources, but it is necessary to conduct experiments to verify that this effectiveness is applicable to real situations. Our field trial was carried out in several study areas distributed in agricultural parcels of SE Spain. Three olive grove and vineyard plantations were monitored for 3 years. Two irrigation water types were considered: freshwater from conventional wells (controls) and treated wastewater (TW). The treated wastewater came from three different wastewater treatment plants (WWTP) that employ a biological secondary treatment without disinfection and different numbers of Inhabitants Equivalent (IE) as a measure of pollutant load. They were located in Valdeganga (3,000 IE), Fuente&amp;#225;lamo (5,600 IE) and Ontur (1,500 IE). All the study plots were watered by drip irrigation using 16 mm-diameter polyethylene pipelines.&lt;/p&gt;&lt;p&gt;Several soil and water parameters were analysed to determine the main differences among them. Increasing of soil salinity is a real risk after irrigating with wastewater as is reflected in higher electrical conductivity values. However, this fact was compensated by the greater contribution of organic matter and nutrients, which allowed crops to adequately develop. Moreover, no microbiological, metal content, toxicity or organic compounds in the studied water samples were detected and reclaimed municipal wastewater was comparable in quality to the conventional sources at all the demonstration sites. Hence adopting this water type for irrigation for grapes and olives could help save primary water resources. The future of water resources management policies involves sustainable wastewater reuse within a circular economy frame because this is the only way to guarantee everyone solidarity access to water.&lt;/p&gt;&lt;p&gt;Fundings provided by the ERA-NET WaterWorks2014 Cofunded Call.

In this paper, after a brief introduction on irrigation wastewater reuse, we take a closer look at Pistoia, the most important nursery area in Italy, which specializes in production of woody ornamental plants. Groundwater resources are used for irrigation in competition with urban use, causing serious shortage problems in summer. Treated municipal wastewater can be a good alternative source of water and fertilizer nutrients for ornamental plant production. During 1998, we carried out an experiment along with local corporate bodies to evaluate the effects of Pistoia's wastewater treatment plant (WWTP) effluent irrigation of the (Pistoia) area – compared with traditional well water irrigation – on three container-grown species, each of them characterized by different growth habits. Plants irrigated with the effluent, treated with UV irradiation in a disinfection pilot plant, showed better physiological and growth parameters than those irrigated with traditional well water.

Wastewater Reclamation And Reuse

The basic aim of this paper is to present an approach to quantitatively assess the potential of municipal wastewater reclamation and reuse in a European context. The model developed is based on the analysis and interrelation of water management data like water availability, water demand and treated effluent. In conjunction with information about the current status of wastewater reuse simple key figures are deduced, which allow future projection of wastewater reclamation and reuse. The simulation points out that there is a significant potential for an increased utilisation of reclaimed wastewater in many European countries, specifically in the Mediterranean region driven by different factors like increased wastewater treatment capacity and higher demand for irrigation and groundwater recharge.

Upper Limit

Chlorination as a disinfectant of tertiary treatment is the most common form in municipal wastewater treatment plants in China. Excess residual chlorine in reclaimed wastewater is harmful to growth of lawn grass. However, upper limit of residual chlorine aimed at reclaimed wastewater reuse for urban green land irrigation has not been promulgated. Lab-scale potted experiments of seedling tall fescue (Festuca arundinacea Schreb.)(TF) and Kentucky bluegrass (Poa pratensis L.)(KBG) were performed to evaluate the effects of residual chlorine in reclaimed wastewater on these two kinds of lawn grass. The results showed that: relative aboveground biomass, photosynthetic rate and total chlorophll (Tchl) concentration reduced to great extent with increasing of residual chlorine. The activity of catalase (CAT) of TF went up under low concentrations and decreased under higher ones, which was different from the decline trend of the same index of KBG. Considered growth of the two kinds of turf grass and disinfectant of reclaimed water, the upper limits of residual chlorine in reclaimed water for landscape irrigation should be equal to 1.0 mg/L for TF and 0.8 mg/L for KBG.

Storage Reservoirs

In arid and semiarid regions the reclamation and reuse of municipal wastewater can play a strategic role in alleviating water resources shortages. Public awareness is growing about the need to recycle and reuse water for increasing supply availability. Many wastewater reuse projects have been put in operation in European and Mediterranean countries adopting extensive treatment systems such as aquifer recharge, lagooning, constructed wetlands, and storage reservoirs, mainly for landscape and agricultural irrigation. In agricultural reuse systems, there is an increasing interest in extensive technologies because of their high reliability, and easy and low cost operation and maintenance. Wastewater storage reservoirs have become the option selected in many countries because of the advantages they present in comparison with other treatment alternatives, namely the coupling of two purposes, stabilization and seasonal regulation. This paper describes an example of a wastewater storage system, built in Caltagirone (Sicily, Italy). The storage results in a tertiary treatment of a continuous inlet flow of activated sludge effluents. The prediction of the microbiological water quality has been evaluated by means of a non-steady-state first-order kinetic model. Single and multiple regressions were applied to determine the main variables that most significantly affected die-off coefficients. The proposed model has been calibrated using the results of a field monitoring carried out during a period from March to October 2000.

Quality Guidelines

Water quality can affect human health in various ways: through breeding of vectors, presence of pathogenic protozoa, helminths, bacteria and viruses, or through inorganic and organic chemicals. While traditional concern has been with pathogens and gastro-intestinal diseases, chemical pollutants in drinking-water supplies have in many instances reached proportions which affect human health, especially in cases of chronic exposure. Treatment of drinking-water, often grossly inadequate in developing countries, is the last barrier of health protection, but control at source is more effective for pollution control. Several WHO programmes of the International Drinking-Water Supply and Sanitation Decade have stimulated awareness of the importance of water quality in public water supplies. Three main streams have been followed during the eighties: guidelines for drinking-water quality, guidelines for wastewater reuse and the monitoring of freshwater quality. Following massive investments in the community water supply sector to provide people with adequate quantities of drinking-water, it becomes more and more important to also guarantee minimum quality standards. This has been recognized by many water and health authorities in developing countries and, as a result, WHO cooperates with many of them in establishing water quality laboratories and pollution control programmes.

Most of the water has been captured in the rivers of Israel and they have turned into dry river-beds which deliver only sporadic winter floods. In a semi-arid country where literally every drop of water is used, reclaimed wastewater is the most feasible water source for river recovery. Two topics are addressed in this paper: water quality management in rivers where most of the flowing water is treated wastewater, and the allocations of reclaimed wastewater required for the recovery of rivers and streams. Water quality management must consider that the main source of water to the river has a pollution loading which reduces its capability to absorb other pollution impacts. The allocation of treated wastewater for the revival of rivers may not affect negatively the water balance of the region; it may eventually improve it. An upstream bruto allocation of 122 MCM/year of wastewater for the recovery of 14 rivers in Israel may favor downstream reuse of this wastewater, resulting in a small neto allocation and in an increase of the water resources available to the country. The discharge of effluents upstream to revive the river followed by their re-capture downstream for irrigation, implies a further stage in the intensification of water reuse.

Abstract Background Ptaquiloside (PTA), caudatoside (CAU) and ptesculentoside (PTE) are carcinogenic illudane glycosides found in bracken ferns (Pteridium spp.) world-wide. The environmentally mobile PTA entails both acute and chronic toxicity. A comparable risk might be associated with the structurally similar CAU and PTE. It is of great health concern if these compounds are present in drinking water, however, it is currently unknown if these compounds can detected in wells in bracken-dominated regions. This study investigates the presence of PTA, CAU, PTE, and their corresponding hydrolysis products pterosins B (PtB), A (PtA) and G (PtG) in water wells in Denmark, Sweden and Spain. Water samples from a total of 77 deep groundwater wells (40–100 m) and shallow water wells (8–40 m) were collected and preserved in the field, pre-concentrated in the laboratory and analysed by liquid chromatography–mass spectrometry (LC–MS). Results Deep groundwater wells contained neither illudane glycosides nor their pterosins. However, seven private shallow wells contained at least one of the illudane glycosides and/or pterosins at concentrations up to 0.27 µg L−1 (PTA), 0.75 µg L−1 (CAU), 0.05 µg L−1 (PtB), 0.03 µg L−1 (PtA) and 0.28 µg L−1 (PtG). This is the first finding of illudane glycosides and pterosins in drinking water wells. Conclusions Detected concentrations of illudane glycosides in some of investigated wells exceeded the suggested maximum tolerable concentrations of PTA, although they were used for drinking water purpose. Contaminated wells were shallow with neutral pH and lower electric conductivity compared to deep groundwater wells with no illudane glycosides nor pterosins.
