Potential Sources of Anthropogenic Pollution

Possible pollution sources in the area include dust, ash, scum, slag, carbon coke residues, minerals, heavy oils, hydrocarbons, and combustion residues. The minerals used to produce cast iron and steel were imported mainly from Africa (Liberia and Mauritania), Canada, India, the former USSR, and from the American Continent (L Industria Mineraria, 1979a). 

The CF groundwater is affected by anthropogenic pollution from urban and industrial pollution urban groundwater pollution typically contains nitrates whereas industrial groundwater pollution typically contains heavy metals and hydrocarbons. It is important to recognize the contamination produced by the upwelling 

In order to properly characterize the brownfield site, before choosing the specific remediation approach, an Expert Committee was nominated by the Government to coordinate and check the remediation activities. This Committee planned the following activities two monitoring phases, which included waste and soil sampling, groundwater sampling, chemical analyses, map compilation for the pollutant elements, data elaboration and interpretation, asbestos characterization and remediation, and a preliminary operative remediation plan. 

Before monitoring operations began, the following documentation was gathered  

After obtaining documentation during the preliminary phase, a full-scale investigation was planned in the entire ILVA and Etemit area to locate and define all polluted areas. The investigation was divided in two phases Phase I was a preliminary general survey and Phase II focused on details from the results of Phase I.
