Key Conclusion: Environmental database radius reports are a tool used by environmental professionals (EP) to evaluate risk to a subject Property. It is up to the EP to decide which databases and which sites are important for a Property assessment.
Environmental database radius reports are ordered from outside companies for typical ASTM due diligence projects. These reports are a tool that is used by the environmental professional (EP) to evaluate risk of off-site sources of contamination to the subject Property. Thus it is up to the EP to interpret the databases and decide which listings require additional evaluation, based on risk to the Property
Current commercially available database reports include a large number of supplemental and proprietary databases. Many of these databases include sites that are duplicate listings of sites in other databases, are lists of sites based on keywords that have them unnecessarily listed as potential risks and on databases indicating the routine and proper use of hazardous materials. Often the Property and many adjacent and nearby sites are found on these exhaustive listings.
ERAS has determined the database sites that are considered to pose the greatest threat to a subject Property, these are listed in our reports and are also at the top of the database listings on the database radius reports. As a normal method of operation, ERAS evaluates ALL the databases on the database radius reports to assess whether sites on supplemental or other databases could pose a threat that warrants further research or other action but does not list repeated or unnecessary sites to pad the report
