“…Responses at species level have received much attention [16,62,63] and often been used to set policy recommendations (e.g., [27,64]), which therefore fail to capture complex interactions (e.g., FS can affect the grazing potential of zooplankton because of changes in the dominance of different groups [65]). However, ecosystem-level responses, including ecosystem functions and services, have been rarely assessed [4,24] (Box S1 in the supplemental information online).…”

“…Based on the aforementioned reasons, this study puts forward some suggestions: (1) To establish a comprehensive UK river water quality dataset as soon as possible; (2) Due to the limited data, this study does not discuss the degree to which the river is affected by acidic input and alkaline input. Future research may be able to make a more comprehensive quantitative analysis from the perspective of atmospheric emissions and changes in base cations; (3) This study does not explore the specific mechanism of the impact of river salinisation and alkalinisation on the environment, such as the chemical cycle of toxic ions in the process of salinisation. To better understand the hazards of salinisation and alkalinisation, this may be a useful direction; (4) Although most rivers in the UK are affected by anthropogenic disturbance (the level of urbanisation in the UK is very high), which means that the results of this study may be applied to more rivers in the UK, there are still some natural rivers that have not been considered.…”

“…River salinisation and alkalinisation are becoming one of the important factors affecting the global river ecosystem [1], which leads to the decline of biodiversity, the degradation of agricultural lands and freshwater areas, and the corrosion of infrastructure, thus threatening human living conditions [2][3][4]. Studying the changes in river salinisation and alkalinisation and analysing their causes will help to better protect freshwater resources and cope with the shortage of freshwater resources.…”

River salinisation and alkalinisation have become one of the major environmental problems threatening the safety of global freshwater resources. With the accelerated climate change and aggravating anthropogenic influences, it is important to identify the trends and causes of river salinisation and alkalinisation so that better mitigation measures could be taken. This study has focused on the UK rivers because there has been insufficient investigation on this topic. To understand the salinisation and alkalinisation trends and causes of rivers in the UK over the past 20 years from a vertical (analysis of each river) and horizontal (comparison of all rivers) perspective, this study uses the Theil-Sen regression and Mann-Kendall test to deal with the trends of conductivity (proxy on salinisation) and pH (proxy on alkalinisation), obtains outliers of conductivity and pH by boxplot, and calculates the Pearson’s and the Kendall’s Tau correlation coefficients (α = 0.05) between the water quality data and the potential factors (potential road salting, normalized difference vegetation index (NDVI), river discharge, agricultural and urban lands). The results show that the UK rivers are becoming more alkaline with a median pH increase of 0.05 to 0.40, but less salty with a median conductivity decrease of 0.06 to 0.11 mS/cm. And the changes in conductivity and pH have seasonality and regionality, which shows that there are usually greater changes in trends and medians of them in winter or through reaches with more anthropogenic disturbance. Furthermore, from a vertical perspective, the conductivity of more than 50% of rivers in this study is negatively correlated with NDVI and river discharge, and positively correlated with potential road salting, and the pH of that is positively correlated with agricultural lands. While from a horizontal perspective, NDVI and agricultural lands are positively correlated with pH, and potential road salting and urban lands are positively correlated with conductivity. Therefore, road salting, urbanisation, agricultural lands, river discharge and vegetation cover can be considered to affect river salinisation and alkalinisation in the UK.

“…Increases are due to human activities including, but not limited to: urbanization, accelerated weathering of rocks by acid rain, weathering of impervious surfaces, agricultural fertilizers, hydrologic alterations, irrigation and evaporative concentration, resource extraction, land clearing, saltwater intrusion, and application of road salts. When major ion concentrations exceed pollution thresholds (and/or interact with complex environmental factors) there can be degradation of agricultural soils, drinking water, biodiversity, and infrastructure, which represent risks to environment, human health, and infrastructure (Cañedo-Argüelles et al 2016b; Kaushal 2016;Iglesias 2020;Lopatina et al 2021). The complex interrelationships between salt ions and chemical, biological, and geologic parameters and consequences on the natural, social, and built environment is called Freshwater Salinization Syndrome (FSS).…”

Freshwater salinization syndrome: from emerging global problem to managing risks

Freshwater salinization is an emerging global problem impacting safe drinking water, ecosystem health and biodiversity, infrastructure corrosion, and food production. Freshwater salinization originates from diverse anthropogenic and geologic sources including road salts, human-accelerated weathering, sewage, urban construction, fertilizer, mine drainage, resource extraction, water softeners, saltwater intrusion, and evaporative concentration of ions due to hydrologic alterations and climate change. The complex interrelationships between salt ions and chemical, biological, and geologic parameters and consequences on the natural, social, and built environment are called Freshwater Salinization Syndrome (FSS). Here, we provide a comprehensive overview of salinization issues (past, present, and future), and we investigate drivers and solutions. We analyze the expanding global magnitude and scope of FSS including its discovery in humid regions, connections to human-accelerated weathering and mobilization of ‘chemical cocktails.’ We also present data illustrating: (1) increasing trends in salt ion concentrations in some of the world’s major freshwaters, including critical drinking water supplies; (2) decreasing trends in nutrient concentrations in rivers due to regulations but increasing trends in salinization, which have been due to lack of adequate management and regulations; (3) regional trends in atmospheric deposition of salt ions and storage of salt ions in soils and groundwater, and (4) applications of specific conductance as a proxy for tracking sources and concentrations of groups of elements in freshwaters. We prioritize FSS research needs related to better understanding: (1) effects of saltwater intrusion on ecosystem processes, (2) potential health risks from groundwater contamination of home wells, (3) potential risks to clean and safe drinking water sources, (4) economic and safety impacts of infrastructure corrosion, (5) alteration of biodiversity and ecosystem functions, and (6) application of high-frequency sensors in state-of-the art monitoring and management. We evaluate management solutions using a watershed approach spanning air, land, and water to explore variations in sources, fate and transport of different salt ions (e.g. monitoring of atmospheric deposition of ions, stormwater management, groundwater remediation, and managing road runoff). We also identify tradeoffs in management approaches such as unanticipated retention and release of chemical cocktails from urban stormwater management best management practices (BMPs) and unintended consequences of alternative deicers on water quality. Overall, we show that FSS has direct and indirect effects on mobilization of diverse chemical cocktails of ions, metals, nutrients, organics, and radionuclides in freshwaters with mounting impacts. Our comprehensive review suggests what could happen if FSS were not managed into the future and evaluates strategies for reducing increasing risks to clean and safe drinking water, human health, costly infrastructure, biodiversity, and critical ecosystem services.
