If a Phase I ESA concludes that an environmental problem may exist, Annelissa’s services are retained to implement a Phase II investigation (subsurface) to confirm the presence of an environmental contamination. Annelissa’s highly trained environmental engineers and geologists are proficient in conducting subsurface investigations relating to various contaminant types and media, collecting samples, and performing speedy analysis. In a rare case, that a site requires a Phase III Investigation, Annelissa’s engineering group provides specialized environmental remediation services, including: designing, constructing, site remediation and monitoring programs to meet the applicable FDEP regulations.
Relevant investigations involve the preparation of detailed contamination assessment plans, preliminary assessment investigations, determining the extent of contamination in accordance with the applicable ASTM Standards or the FDEP Chapter 62 Regulations. An accurate assessment of the site contamination data has a profound effect upon defining the extent of the contamination, site assessment and eventual remediation cost-effectively. Various interrelated aspects to investigation execution are involved such as field logistics, drilling techniques, sampling protocols, and general concepts of contaminant movement and remediation. Additionally, we must take into consideration project budget, client interaction, regulatory requirements and legal implications.
On occasions, the contamination at a site does not satisfy the No Further Action (NFA) criteria or the Natural Attenuation Monitoring (NAM) criteria of the FDEP regulations. Therefore, a Remedial Action Plan (RAP) is prepared with the understanding that active remediation will achieve the applicable NFA criteria or the NAM criteria of the FDEP rule. The RAP provides a design that addresses cleanup of all contaminated soil, sediment, and groundwater. Annelissa evaluates several remedial technologies such as excavation, groundwater extraction, air sparging/soil vapor extraction, and bio-remediation. Annelissa has successfully remediated sites from a variety of contaminants types including, but not limited to petroleum and gasoline contamination, chlorinated compounds, and metals such as lead, arsenic, and chromium in soil and groundwater.
