PPM has conducted hundreds of human health and ecological risk assessments over a wide geographic area with a variety of chemicals of concern. PPM was one of the first firms to conduct risk assessments in Louisiana, Mississippi, and Alabama, and is a leader in developing site-specific corrective action limits at soil and groundwater contamination sites. PPM’s track record in gaining regulatory agency approval of higher corrective action limits based on site-specific risk factors often results in significant savings in remediation costs for our clients.
