Nanoparticles, due to small size and capacity to remain in suspension, are very efficient to remediate aquifers contaminated. However, due to their small size, while nanoparticles are traveling through porous media, they can rapidly aggregate, causing their settling and deposition. These phenomena produce issues for in situ remediation, such as the loss in chemical reactivity and the unknowing about the nanoparticles distribution when they are injected in situ. Laboratory experiment has been carried out with groun...

Water crises have become more and more frequent in recent years. In fact, the ongoing climate changes have led very often to periods of drought, which, together with the increasing of groundwater exploitation, leads to a depletion of thess resources, which are fundamental for human life. Most of the most important springs, in the world, are located in karst areas. Specifically, for a large part of the Mediterranean region, karst springs play an essential role in water supply systems. The quantitative analysis of k...

Drought events are currently increasing in frequency and intensity all over the world as effect of climate change. One of the most related environmental issue is water resource scarcity, which is now becoming an emergency also for several industrialized countries in the Mediterranean area. In the summer of 2017, all Italian territory suffered from an extreme drought event that caused huge depletions of both groundwater and surface water availability. In particular, Bracciano Lake, which is one of the largest surfa...

The need of increasing the use of alternative materials, in construction and in production, is a current issue worldwide. At the same time, with regard to the treatment of waste, the management of bottom ash coming from Municipal Solid Waste Incineration, is an important issue all over the world, especially in Italy. In fact, the need for right management of ashes increases, which, in Italy, are almost always disposed of in landfills. This paper presents the environmental aspects of an industrial experiment, in Ce...

In Italy, the summer of 2017 was characterized by serious problems related to the water crisis that affected the entire national territory. The Municipality of Formia, as well as many other territories in the Latina Province, had to face heavy rationing of the water supply during the summer, with consequent inconvenience for the population. In this paper, two spring and their relative aquifers were studied: the Mazzoccolo Spring and the Capodacqua di Spigno Spring. For both aquifers, a hydrogeological water balanc...

The purpose of the present study, included in the research project SECOSUD Phase II, called ?Conservation and equitable use of biological diversity in the SADC region (Southern African Development Community) [1], is to describe the existing baseline situation in term of geological and hydrogeological conditions of the Kruger National Park, providing a starting point for understanding the water resources status quo, potential hydrogeological issues and concerns to assure a sound and correct water resources manageme...

Groundwater represents worldwide the main reserve of freshwater for human needs. The increasing demand, combined with the use of unsustainable systems for groundwater management, leads to a remarkable decay in its quality and quantity, especially in many cities of the Global South, where the fast urban growing frequently bring to environmental critical issues as the case of seawater intrusion for coastal aquifers. Dar es Salaam, in Sub-Saharan Africa, is one of these cities, with more than 4 million of inhabitants...

Sustainable use of natural resources and recycling/reuse of wastes are two of most current upcoming environmental problems, and they play an important role in the circular economy, as recycling of waste can give an important contribution to the reduction of natural resources. Ceramic tiles production is one of the industrial activities involved in using natural resources like clays and sands. On the other hand, in Italy, sanitary landfills are, nowadays, the main place, where bottom ashes are finally treated. This...

This paper deals with the first results coming from the research activity of the SECOSUD Phase II, called пїЅConservation and equitable use of biological diversity in the SADC region (Southern African Development Community) a project supported by the Italian Ministry of Foreign Affairs in the SADC [1]. The goal of this tiered study is to give an integrated view of three focus themes inside the area of Limpopo National Park, in Limpopo River Basin: groundwater, climate change, biodiversity. Limpopo National Park is...

This paper deals with the results coming from the research activity of the SECOSUD Phase II, called пїЅConservation and equitable use of biological diversity in the SADC region (Southern African Development Community) a project supported by the Italian Ministry of Foreign Affairs in the SADC [1]. In the framework of this project they have been investigated groundwater resources and shallow ones present in the buffer zone of National Limpopo Park, in the aim of better support water demand in the villages, rising in...
