SoilContamination

-- Name -- groundwater profile -- Definition -- body of groundwater with boundaries in 3 dimensions (surface and depth) characterized by some property (the value of a certain parameter). -- Description -- Used in connection to pollution: giving the extent of the groundwater body that is polluted over a threshold value of concentration of a certain pollutant. Generally it is dynamic and dependent on flow rates of the groundwater, the presence of dense soil layers, solubility and adsorption/desorption behaviour of the pollutants.

-- Name -- contaminated soil site -- Definition -- Site on which manmade substances are present in levels and amounts considered to be a hazard, in soil, groundwater and waste (on or below surface level). -- Description -- Site where levels of contaminants in soil or groundwater are or were above applicable threshold values, as concluded from a main site investigation and over a surface or in a volume not to be neglected (up to local regulations and authorities). Irrespective of the current status of management measures or temporary safety measures taken or to be taken after risk assessment.

-- Name -- possibly contaminated soil site -- Definition -- a site with a suspicion of pollution above threshold values which has not been confirmed by a main site investigation with a verdict of the local authority. -- Description -- It is always the candidate for further investigations, generally with a tiered approach in which it will remain possibly polluted until after the main site investigation in which hazards may be confirmed or rejected.

-- Name -- investigated chemical parameter type -- Definition -- Chemical parameter for which the exceeding of threshold values for a substantial are is confirmed or rejected. -- Description -- In main site investigation.

-- Name -- contamination activity type -- Definition -- classification of contaminating activities. -- Description -- Generally the character of the contaminating activities is: emissions, leaking and spills from industrial production, trade and storage, waste handling, defense, fire and transport calamities.

-- Name -- measure taken type -- Definition -- type of measures taken in response to the hazard and risk assessment. -- Description -- Measures to take away the risk by blocking exposure and dispersion paths, by cleaning, stabilizing or isolation, also temporay safety measures.

-- Name -- risk type value -- Definition -- type of exposure route for risk receptors. -- Description -- in relation to type of pollutants

-- Name -- soil contamination specialised zone type code -- Definition -- Indicates restrictions on the site as a consequence of the current situation. -- Description -- Imposed restrictions in land use

-- Name -- investigation trigger value -- Definition -- trigger to have a site investigated or to investigate it in the future. -- Description -- On the basis of recognised problems (confirmed compliants, encountered high concentrations of hazardous materials, etc.) or expected problems (inventory of potentially polluted sites).

-- Name -- measure taken value -- Definition -- type of measure taken to manage pollution. -- Description -- e.g. cleaning, isolation, change land use

-- Name -- contaminating activity presence value -- Definition -- status of contaminating actvity. -- Description -- Historical, recent, ongoing, or not a regular actvity but a calamity.

-- Name -- risk receptor value -- Definition -- entities exposed to pollutants at the site. -- Description -- e.g. inhabitants, groundwater well, nature reserve

-- Name -- measure taken status value -- Definition -- status of measures at the site. -- Description -- proposed, in progress, executed

-- Name -- measure taken status value -- Definition -- stage in which measures are taken. -- Description -- During investigation (safety measures), definitive measures, aftercare.

-- Name -- NACE industrial activity value -- Definition -- Industrial activity according to NACE. -- Description --

-- Name -- investigation state value -- Definition -- status of investigations. -- Description -- Based on a tiered approach, starting with: not investigated yet, first step of the investigation in progress, ending with: investigated and verdict on the state of pollution given (by local authority).

-- Name -- other contaminating activity value -- Definition -- for polluted sites: activity which polluted the soil and groundwater on the site. For inventories of potentially polluted sites: the activities present on the site which have a potential for polluting soil and groundwater, dependent on processes, size an management. This list is an extension of the NACE codelist of industrial activities and made to cover other types of possibly polluting activities. -- Description -- This value may help to focus investigations on the chemical parameters of importance (probability and amounts present).

-- Name -- risk assessment stage value -- Definition -- status risk assessment. -- Description -- Recognition of risk receptors and exposure routes, up to full assessment of levels of risk and dispersion.

-- Name -- waste type value -- Definition -- Waste types encountered at the site. -- Description -- non-exhaustive list of waste materials, to help to recognise the expected problems at uncontrolled waste landfills and dumpsites.

-- Name -- contaminating activities value -- Definition -- Historical or current activity on the site in which use, handling and storage of significant amounts of relevant hazardous materials occurs or has occurred and may have lead to soil and/or groundwater pollution, including events (e.g. calamity) with effect on soil and/or groundwater contamination. -- Description -- Also including now obsolete (industrial and commercial) activities which left a mark on the soil (e.g. city gas works, gas light mantle production). ContaminatingActivitiesValue is a union class (choice) that shall support two possible codelists i.e. either NaceIndustrialActivityValue or OtherContaminatingActivityValue
