Notes (for further explanation see section 5.3): 1 CLEA is not currently intended for use as a fully site specific risk assessment model, however the methodology is the key guidance in the UK. 2 ConSim is a stochastic groundwater fate and transport model and is intended for use with the P20 methodology, P20-RTW is recognised as the preferred package within the UK regulatory

environment. RAM is also based on the P20 methodology, and is therefore not considered in preference to P20- RTW. 3 ROME is considered in preference to Giuditta as it has been developed by ANPA (National Agency for Protection of the Environment). 4 JAGG and P20-RTW do not quantify dose concentrations for human health, however receptor point concentrations are generated and can be compared to output from other models and to

quality standards. 5 The Norwegian and Swedish models are similar with the Swedish system pre-dating the Norwegian system. The Norwegian system has been selected as the guidance clearly states its

suitability for site specific risk assessment where there is no similar comment in the Swedish manual. It has since been ascertained that the Swedish system is also frequently used to calculate site specific risk based guidelines.

6 At the time of system evaluation SNIFFER was not available in software format, is used in implementing the same legislation as CLEA and reflects the guidance in the CLEA reports CLR9 and CLR10.

Notes: 1 Risk levels have only been considered for benzene and trichloroethene to distinguish between the analysis of threshold and non-threshold compounds. 2 The indoor air pathway has not been modelled in CLEA as the sub-model in the current software is due to change. 3 JAGG was not included in this part of the comparison study as Arcadis were unable to ascertain how / if the model (only available in Danish) predicted the concentration

in indoor air from a groundwater source. Following feedback from the Danish EPA subsequent to the presentation of results at ConSoil 2003, Arcadis acknowledge that JAGG can be used to model this pathway.

3. UMS also requires the definition of a Resorption factor, which has also been changed to the default value. This factor is specified for ingestion, dermal contact and inhalation and was set at 100% for the GTS. For the default data set ingestion and inhalation remain as 100% but the dermal contact value (accounting for the amount of contamination absorbed through the skin) reduces to 3.5%

1 RBCA always considers risk based on adult exposure.2 RBCA adds together inhalation of indoor air from a soil and groundwater source thereby increasing the predicted risk level.3 In Risc-Human a lifelong dose (using lifetime of 5 years for child and 65 years for adult) is defined.4 The output from Risc-Human combines all pathways; the risk level is based on a reduced indoor air dose as this cannot be doubled to account for a basement as was done in the dose comparisons. 5 In Risc-Human only one inhalation rate can be defined, resulting in relative underestimation of the inhalaition of dust outdoors.6 Risks levels based on inhalation from UMS include the risks from inhaling dust indoors in addition to risks from inhaling indoor air.7 Lifelong dose (using lifetime of 6 years for child and 64 years for adult).8 The output from Vlier-Humaan combines all pathways and includes additional pathways: inhalation of dust inside, ingestion and dermal contact with dust indoors, thereby increasing the predicted risk level.9 Risk level unchanged from GTS.
