Recent developments of Middle Eastern metropolitans, and the related soaring trend of population increase, is contemporary with the impacts of climate changes. This applies extra pressures to the centralized large-scale water treatment and distribution systems. Rainwater harvesting (RWH) for domestic urban activities can be a sustainable option of adapting with the rising demand of soft water in such an arid/semiarid area. A pilot system of rainwater draining and storage was constructed for alleviating parts of soft water scarcity in Mashhad, the second most populous city of Iran. Measurements were collected for two years at the drainage basin outlet and inside of a storage tank, which has been equipped for water harvesting purposes. We performed some preliminary stochastic analysis and evaluated probabilistic properties of the collected dataset, aiming to explain them with respect to the physical characteristics of the RWH system. Data clustering analysis confirmed that the quality of the water may change during rainwater draining and storage in the RWH tank. Particularly, sodium content of the sampled water in the drainage catchment illustrated higher variations, compared with the ones evaluated for the stored water in the reservoir tank. This can confirm that the quality of the stored water in the RWH reservoir is more stable than that obtained for each separate rainfall–runoff event. We assessed the potential of the harvested water in different consumption contexts, in light of some national and international water quality (physicochemical, biological, and toxic pollutants) guidelines. We relied on water quality indices (WQI) to interpret multiparametric properties of the collected rainwater from urban surfaces; consequently, the quality of the harvested water was categorized with moderate to almost good attributes. This makes it well suited for irrigation uses, which can play a relevant role against water shortages in the analyzed semiarid urban region. Otherwise, infiltration and treatments need to be performed if using harvested water for drinking consumptions (of human or livestock), some of which may be costly for local owners/uses. We provide some suggestions for improving efficiency of the system and enhancing the quality of the harvesting water.

Abstract We analyzed the studies on the hydrochemical composition in the Argun basin and evaluated the level of pollution. We found that the water of the Argun River was contaminated by organic substances and toxic elements. We distinguished 9 major types of the ecosystems based on the prior findings. The prevalent species of Cladophora fracta was chosen as an indicator for the monitoring of the Argun drainage basin pollution by toxic elements. The concentrations of toxic elements in algae remained unchanged for a long term and they appeared to be more informative for the assessment of pollution than the rapidly changing water quality. It is necessary to determine indicator hydrobionts for each type of the ecosystems within such a vast territory as the Argun basin. Our findings showed that current mining production produces a negative ecological impact on the quality of the water ecosystems which should be considered during further developments. It is necessary to conduct a research on the regional background concentrations for toxic elements in water and hydrobionts, and to enlarge the list of indicator hydrobionts for water quality assessment.

AIM: To assess water quality of three lakes located in an abandoned coal mining area, in the Morozini River basin (Treviso, Santa Catarina State, Brazil). METHODS: The study sites were three lakes mining pits flooded after deactivation, near the drainage basin of the Morozini River (Treviso City, Santa Catarina State, Brazil). Samplings were carried out in profile in the limnetic region during two seasons (Summer in February and Winter in July). RESULTS: In general, the three lakes showed high concentrations of SO4-2, Mg, Fe, Al, Ca, Ba, Si, Zn, Ni, Na, K, Sr, B, Cd, Cr, Pb and Cu. CONCLUSIONS: Coal mining activity and waste disposal practices adopted by the mining companies in the Morozini River basin have drastically affected the water quality of the examined lakes and made them inappropriate for diverse human uses, such as leisure, swimming and fishing.

In this work we performed a geographical analysis of the Moravica spring locality in the Sokobanjska Moravica drainage basin in Serbia, as well as an analysis of the physical, chemical, and biological parameters of the water during a one-year period. The basic sanitary characteristics and physical, chemical, and biological parameters, necessary for understanding locality conditions, were studied, and the saprobity index, class of quality, O/H index, degree of saprobity, degree of trophicity, and category based on the phosphatase activity index (PAI) were determined. Our results point to the need for continual monitoring of the water quality in the spring locality.

The aim of the present study was to determine the environmental characteristics and water quality of a drainage basin impacted by human activities in order to obtain quantitative information for helping the development of environmental management politics of soils, lakes, rivers and water resources. Physicochemical properties and concentrations of metals were determined in different water samples. Dissolved oxygen, pH, turbidity, color, ammonia, phosphorus, phenol, copper, silver, lead, cadmium and iron differed from levels considered acceptable by international regulations, indicating potential environmental pollution due to land occupation and the improper disposal of domestic, industrial and agricultural waste. The leaching of pollutants from the soil to bodies of water was also found. Total dissolved solids, salinity, suspended solids, nitrate, nitrite and zinc levels were lower than the limits imposed by international regulations, but have been increasing over time. Urbanization, industrialization and agricultural processes in drainage basins significantly affect the natural characteristics of the environment, leading to an increase in the concentrations of pollutants and a reduction in the quality of water, plants and soils. As pollutants in drainage basins generally enter into soils, rivers, lakes and ocean, it is necessary to obtain quantitative information about the human impacts in the water quality for developing environmental management politics aiming to preserve the water resources.
