The tannery industry is an integral part of economic development in many developing countries, and the environmental pollution caused by the tannery industry cannot be ignored. In this study, soil and groundwater samples at different depths were collected from an abandoned tannery to investigate...

The groundwater system is polluted by chlorinated hydrocarbon pollution in eastern Jinan, Shandong province, China, exceeding the limit of pollutants concentration in class III of Groundwater Quality Standards (GQS, GB/T 14848-2017). In order to improve the current situation of chlorinated...

Wastewater is contaminated water that must be treated before it may be transferred into other rivers and lakes in order to prevent further groundwater pollution. Over the last decade, research has been conducted on a wide variety of contaminants, but the emerging contaminants are those caused...

With the development of technology, the concepts of "green" and "sustainable" have gradually been popularized in all walks of life. With the continuous development of the world mining industry, the efficiency of resource development in various countries has been improved, but mining activities and...

Iron (Fe) is one of the most biochemically active and widely distributed elements and one of the most important elements for biota and human activities. Fe plays important roles in biological and chemical processes. Fe redox reactions in groundwater have been attracting increasing attention in the...

The risk assessment of groundwater pollution sources plays an important role in groundwater protection, the divisions of pollution prevention and control areas. However, existing methods underestimate the potential risk of combined pollution of groundwater from point sources. In order to evaluate...

It is important to study the source-sink relationship of pollution. However, research on the groundwater pollution sources and pollution sinks has often been conducted separately in the past, which makes it difficult to study the source-sink relationship of pollutants. In this study, the source and ...

The oil industry is one of the causes of environmental pollution by oil spills due to drilling and extraction. In case of oil leakage from oil wells to soil and then groundwater, it leads to the movement of pollutants and the spread of pollution by groundwater. In the study area, due to the...

The biogas slurry (BS) is a kind of residue liquid of biogas produced by anaerobic fermentation with livestock and poultry manure as the main raw materials. The biogas project in China began in the 1970s. With the development of livestock and poultry farming, and anaerobic digestion technology of...

A large in-service petrochemical enterprises in Northeast China was taken as the research object, and the Collaborative Monitored Natural Attenuation (CMNA) for soil and groundwater pollution was carried out to remedy combined pollution and reduce environmental risks. The pollutants distributions...
