Abstract This paper aimed to determine the grey water footprint (GWF) of groundwater resources. The effect of groundwater recharge on grey water footprint was investigated in Southeastern Turkey. In this paper, GWF has been monitored in October and March in terms of nitrate and arsenic concentrations for ten observation wells in the Harran Plain. In this study, a new approach was developed based on the GWF to determine the nitrate and arsenic pollution of groundwater. GWF of coagulation-flocculation and biochar adsorption processes were calculated and benchmarked with each other. In the second stage of the study, the effect of groundwater recharge using reclaimed municipal wastewater on GWF was investigated applying Monte Carlo simulation. The results revealed that nitrate led to higher GWF. According to the results, biochar application could reduce the GWF. Total reduction of GWF would be approximately 64.3% if groundwater recharge using reclaimed wastewater is applied. HIGHLIGHT The novelty of this study is that a new estimation model has been adapted for grey water footprint of groundwater resources. The other originality of this work is biochar application for groundwater treatment. Biochar application was carried out to treat groundwater in order to observe the GWF. Urfa Isot pepper which is traditional crop of Turkey was used to generate biochar with slow pyrolysis.

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.

Cíle udržitelného rozvoje OSN požadují mimo jiné i zlepšit kvalitu vody snížením jejího znečišťování, zamezením vyhazování odpadů do vody a minimalizací vypouštění nebezpečných chemických látek do vody. Jedním z nástrojů, který lze využít pro posouzení udržitelnosti vypouštění znečištění do vod je vodní stopa. V článku je popsána analýza šedé vodní stopy velkých komunálních čistíren v povodí Ohře. Pro analýzu byly vybrány komunální čistírny odpadních vod uvedené státním podnikem Povodí Ohře ve zprávách vodohospodářské bilance. Byla stanovena asimilační kapacita toku pro jednotlivé znečišťující látky hlášené provozovateli čistíren odpadních vod pro účely vodohospodářské bilance, spočtena šedá vodní stopa látek vstupujících na čistírnu odpadních vod (produkované znečištění) a vypouštěných do recipientů v odpadní vodě. Posouzení udržitelnosti bylo provedeno k dlouhodobému průměrnému průtoku recipientem. Analýza ukázala, že asimilační kapacita vodních toků je nejvíce vytěžována vypouštěním celkového fosforu a amoniakálního dusíku. Zároveň z analýzy vyplynulo, že čistírny odpadních vod, až na výjimky, čistí vodu dostatečně a asimilační kapacita vodního toku nebývá vyčerpána. ----------- The Sustainable Development Goals (SDGs), adopted by all United Nations Member States in 2015, call, among others, for the improvement of water quality by reducing water pollution, avoiding waste disposal in water and minimizing hazardous chemicals discharge into water. One of the tools that can be used for the sustainability assessment of pollution discharge into water is the water footprint. The paper calculates the grey water footprint of large municipal wastewater treatment plants in the Ohře River basin, located in the Czech Republic. Municipal wastewater treatment plants listed by the state-owned enterprise Povodí Ohře in Water Balance Management reports were selected for the analysis. The receiving body assimilation capacity for individual pollutants was determined and the grey water footprint at the inlet and outlet of the WWTP was calculated. Subsequently, the sustainability assessment of the WWTP discharges were carried out and related to the long-term average flow rates in the receiving water body. The analyses showed that the assimilation capacity of the watercourse is mostly utilized by the discharge of total phosphorus and ammonia nitrogen. The analysis also showed that (with some exceptions) the wastewater treatment plants treat water sufficiently and the assimilation capacity of the watercourse is not exhausted.

Climate change can directly or indirectly influence groundwater resources. The mechanisms of this influence are complex and not easily quantified. Understanding the effect of climate change on groundwater systems can help governments adopt suitable strategies for water resources. The baseflow concept can be used to relate climate conditions to groundwater systems for assessing the climate change impact on groundwater resources. This study applies the stable baseflow concept to the estimation of the groundwater recharge in ten groundwater regions in Taiwan, under historical and climate scenario conditions. The recharge rates at the main river gauge stations in the groundwater regions were assessed using historical data. Regression equations between rainfall and groundwater recharge quantities were developed for the ten groundwater regions. The assessment results can be used for recharge evaluation in Taiwan. The climate change estimation results show that climate change would increase groundwater recharge by 32.6% or decrease it by 28.9% on average under the climate scenarios, with respect to the baseline quantity in Taiwan. The impact of climate change on groundwater systems may be positive. This study proposes a method for assessing the impact of climate change on groundwater systems. The assessment results provide important information for strategy development in groundwater resources management.

Water footprint is a volumetric indicator of freshwater appropriation. The grey water footprint (GWF) provides a tool to assess the water volume needed to assimilate a pollutant. However, evaluating the impact on water environment cannot rely solely on volumetric consumption of freshwater. It demands accurate assessment criteria to reflect its environmental and ecological effects on ambient water resource. In this paper, a new assessment method is proposed: the effluent toxicity and the Potential Eco-toxic Effects Probe (PEEP) index of aquatic environment are taken into consideration. This method provides a comprehensive indicator for evaluating water footprint, specified in effluents’ ecological impact on ambient water sources.

The State of California's WastewaterReclamationCriteria is under review and will be revised and expanded to include several new regulations on the use of reclaimed municipal wastewater. To provide a scientific basis for the evaluation of the existing and proposed Criteria, enteric virus monitoring data from secondary and tertiary effluents were evaluated. These virus data were obtained from special studies and monitoring reports, covering the period from 1975 to 1989, including ten municipal wastewater treatment facilities in California. Based on the enteric virus data from these reports, and using the current Criteria as a guide, four exposure scenarios were developed to determine the risk of waterborne enteric virus infection to humans as a consequence of wastewater reclamation and reuse. The exposure assessments included food crop irrigation, landscape irrigation for golf courses, recreational impoundments, and ground water recharge. The virus enumeration and the resulting risk assessments described in this paper provide a comparative basis for addressing the treatment and fate of enteric viruses in wastewater reclamation and reuse. The analyses show that annual risk of infection from exposure to chlorinated tertiary effluent containing 1 viral unit/100 L in recreational activities such as swimming or golfing is in the range of 10−2 to 10−7, while exposures resulting from food-crop irrigation or groundwater recharge with reclaimed municipal wastewater is in the range of 10−6 to 10−11. The risk analyses are also used to demonstrate that the probability of infection can be further mitigated by controlling exposure to reclaimed wastewater in the use area.

The proposed California regulations for groundwater recharge with reclaimed municipal wastewater are presented with the basis and rationale for key requirements. The treatment and recharge basin requirements have been developed to control the migration of pathogens, nitrogen, and trace organics in the extracted groundwater. The regulations rely on a combination of controls intended to maintain a microbiologically and chemically safe groundwater recharge operation. These regulations provide uniform statewide criteria that will promote groundwater recharge projects using reclaimed municipal wastewater.

Despite the continuous increase in water supply from desalination plants in the UAE, groundwater remains the major source of fresh water satisfying domestic and agricultural demands. Additionally, groundwater has always been considered as a strategic water source towards groundwater security in the country. Quantification of groundwater recharge is a prerequisite for efficient and sustainable groundwater resources management in arid regions. Therefore, groundwater recharge from the ephemeral Wadi beds and subsurface flow from mountainous valley beds play an important role in water management. Although, both surface and groundwater resources in UAE are scarce; the anticipated climate change impacts could make these resources even scarcer. As such, the main aim of this paper is to assess the potential impacts of future climate variability and change on groundwater recharge in the eastern region of UAE. This paper will explore rainfall characteristics in the region, their projections and their impacts on Wadi hydrology and groundwater recharge processes. Another objective of the study is to identify groundwater recharge regions to the shallow unconfined groundwater aquifer in the northeastern part of Abu-Dhabi Emirate. Outcomes of this study will help to accurately estimate current and future sustainable extraction rates, assess groundwater availability, and identify pathways and velocity of groundwater flow as crucial information for determining the best locations for artificial recharge.
