The word Remediation comes from the Latin REMEDIARE, which means “TO HEAL”, Pollution , comes from the Latin POLLUTIO which means exactly “POLLUTION”, “CONTAMINATION”. Pollution, contamination of the environment and in particular, for the case in subject, ground contamination, is a continuous process, and a great part of it is being done by human activities, such as careless dumping of urban refusals, including heavy metals (e.g. cadmium) hospital waste, raw sewage , indiscriminate dumping by the chemical industry of harmful by-products, factories' effluents, dumping of animal waste (e.g. from piggeries} without proper treatment, which produce harmful lechates, improper disposal of mine tailings, including mercury, spilling of petroleum products, among others.
Everybody can easily see the most common kind of pollution of the environment done by indiscriminate and unregulated dumping of urban refusal of any kind, we can also, without effort , observe the visual effects of water pollution in rivers, lakes and the sea-coast areas, even at the early stages of pollution: it is instead difficult if not totally improbable to be able to observe in a casual way the damage done to water table/aquifer by the introduction of harmful substances or products into the ground.
The contamination of the water table/aquifer is an insidious type of pollution. Here the use of the word “insidious” is neither done by chance or for drama , but to emphasize the fact that contamination of the underground waters has become a worldwide (man-made) calamity because it happens over time, slowly, generally undetected.
The most common cases of aquifer contamination are produced by the combination of indiscriminate dumping of wastes of any kind or industrial by-products potentially toxic, with rainwater or surface waters, resulting into the production of toxic lechates percolating into the aquifers.
Generally when the pollution, contamination or poisoning of water table are detected, it is because the damage to the aquifers is already so great that the effects of water contamination have been taking a toll on public health and the only available solution is finding alternative sources of fresh water, (with the complication that natural alternative sources of fresh water might not be easily available).
The “soil remediation” into which Foundation Specialists has poured years of research and development activity, is dealing with isolating or encapsulating the polluted soil (or ground in the generic sense) to prevent pollutants and contaminants from leaching into the aquifers.
Foundation Specialists research and development of technologies dealing with “soil remediation” has been continuous, theories and design have been subjected to field verification and testing all the way, to assure the applicability and adaptability of technologies to varied field conditions to verify the results of the interventions and the consistency of the results obtaining , both on the short and the long term.
In a nut-shell, the soil remediation technologies developed by Foundation Specialists are designed to isolate the sources of pollution by surrounding them, all around and under, with a totally impervious curtain or cut-off medium, non-degradable with time and indefinitely lechate-resistant.
The curtain or cut-off has to be also made in such a way to remain indefinitely able to stretch and deform following the settlements and deformations of the surrounding ground, in order to avoid forming cracks that would allow loss of lechates from the contained areas.
A great advantage of the soil remediation technologies developed by Foundation Specialists is their adaptability, in fact they can also be used as very efficient "ground conditioning", for the preparation of landfill areas or dumps.
With a little foresight , Public Officials and Urban Planners, can intoduce these technologies at the planning stage of landfills and apply the technologies in the field when preparing the landfill areas to receive urban refusals. In so doing, the introduction of these technologies during the preparation stage of landfills prevents damages to the environment. Preventing pollution of the environment is obviously more beneficial to public health and the environment than having to resort to remediation to remove or neutralize the sources and the effects of ongoing pollution.
