Environmental Investigations specialise in conducting field-based investigations for lead. This would involve a site visit by one of Environmental Investigations experienced environmental scientists or engineers, who will collect soil or water samples from strategic locations (typically children's play areas and gardens). All samples are collected in accordance with published environmental sampling procedures, and delivered to a NATA-registered, environmental laboratory in your city.

 Analytical results will generally be returned in the form of a letter report, which documents how the investigations was conducted and includes a plain-English interpretation of the identified contaminants concentrations in relation to current EPA Health-Based Investigation thresholds. Should the tested concentrations exceed the EPA Quality Criteria for land use, then recommendations will be presented to advise of available options for managing any affected soil or water, to prevent undue risks to human health or the environment.
