“…The lower values of COD and BOD5 in the surface water relative to its values in the leachates indicates higher values of dissolved oxygen in the river relative to the leachates samples from the dumpsites. Present findings revealed that the leachates may be potential source of adjacent water sources contamination, also previous findings documented that the leachates are one of the main sources of river water contamination (Ayandiran et al, 2018;Camaño Silvestrini et al, 2019;Deng et al, 2019;Hobson et al, 2018;Kang et al, 2019;Kayembe et al, 2018;Mor et al, 2018;Qu et al, 2019;Rai et al, 2019;Rezapour et al, 2018;Scandelai et al, 2018;Tanikawa et al, 2018;Wu et al, 2018;Xiong et al, 2018;Xu et al, 2018;Yuan et al, 2019;Zhao et al, 2018).…”

The physicochemical characteristics and heavy metal levels of leachates at the Rumuodumaya dumpsites and the surface water of its adjacent river was investigated by appropriate field instrument for in situ measurement, standard procedures and AGILENT 55B spectra for the heavy metals. The results from the dumpsites and surface water of the river generally indicate that as of the time of analysis, there is no serious threat to its immediate environment except the nickel concentrations in the dumpsites and surface water of the river, respectively and whose values were beyond the recommended limit of WHO/USEPA (0.05 mg/L) for safe drinking water. The trend of the results also indicates that the dumpsites are sources of numerous soil and water pollutants capable of depleting oxygen levels in the river and this could pose several and serious health risk to humans and aquatic life. Adequate solid waste disposal technique should be adopted by the appropriate agency to forestall this threat to the Rumuodumaya environment.

“…On the one hand, with more restrictive regulations and higher numbers of new landfills with good groundwater protection technology, the leachates from wastewater will be reduced. On the other, the already existing landfills will have more leakage because of the aging of geo-membranes, and such aging increases the risk of the deterioration of > 87% removal of antibiotics and other micropollutants (Gorito et al 2018) groundwater quality, and creates a problem for the future (Xu et al 2018). Thereby, the most effective action is the prevention of the disposal of pharmaceuticals to landfills.…”

The global problem of the presence of human and veterinary pharmaceuticals in the environment is under investigation. Despite the increase in the knowledge of its sources, fates and impacts, the assessment of risks and the derived prevention actions are limited to single cases. The predicted increasing trend in the usage of pharmaceuticals forces the various parties involved to think about comprehensive mitigation actions. There are many areas of daily human life and industrial operations where such actions should take place. Thereby, in the presented review, such actions were summarized and divided into the following groups: A. design, synthesis and production of pharmaceuticals, B. prescription, sales and waste handling, C. control of the sources with advanced technologies. As the total amount of proposed actions was found to be quite high, a ranking according to the term of effects was proposed using the pyramid of needs. The advantages of actions taken in the first steps of the pharmaceutical life cycle (acting on the upstream) over end-of-pipe actions and the application of advanced technologies (the downstream option) were discussed, with reference to expert opinions.

Mass construction and operation of hazardous waste landfill infrastructure has greatly improved China’s waste management and environmental safety. However, the deterioration of engineering materials and the failure of landfill may lead to the release of untreated leachate rich in persistent toxic pollutants to the soil and shallow groundwater. Accordingly, we develop the framework and process model to predict landfill life by coupling the landfill hydrological performance model and material degradation model. We found that the decrease rate of the concentration of persistent pollutants in leachate was significantly slower than the deterioration rate of the landfill engineering materials. As a result, when the materials failed, the leachate with high concentrations of persistent pollutants continued to leak, resulting in the pollutants concentration in surrounding groundwater exceeding the acceptable concentration at around 385 a, which is the average life of a landfill. Further simulation indicated that hydrogeological conditions and the initial concentration of leachate will affect landfill lifespan. The correlation coefficients of concentration, the thickness of vadose zone and the thickness of aquifer are − 0.79, 0.99 and 0.72 respectively, so the thickness of vadose zone having the greatest impact on the life of a landfill. The results presented herein indicate hazardous waste landfill infrastructure reinvestment should be directed toward long-term monitoring and maintenance, waste second-disposal, and site restoration.
