Brownfield Assessment/Remediation

Matanzas completed a limited soil and groundwater investigation to evaluate soil and groundwater quality associated with a former wood treatment facility and forestry field office. Matanzas assisted the new property owners with the submittal and formal acceptance of a Brownfield Site Rehabilitation Agreement. Innovative cleanup approaches such as in-situ chemical reduction of arsenic and phytoremediation are currently being implemented and evaluated.

SPCC and SWP3

To meet new regulatory guidelines, the Florida Rock Division of Vulcan Materials Company hired Matanzas to revise more than 100 Spill Prevention Control & Countermeasure (SPCC) and Stormwater Pollution Prevention Plans (SWP3) in a 14-month period. SPCC plans identify methods and equipment necessary to minimize the hazards to human health or the environment and prevent any sudden or non-sudden release of petroleum and non-petroleum products or lubricants to the air, soil, surface water, and ground water at the regulated facilities. SWP3 are site-specific plans that evaluate potential sources of pollution handled, used or stored on a site and document the appropriate measures to prevent or control the discharge of pollutants in storm water runoff.

Riberia Street Corridor Investigation

Matanzas performed a Phase I ESA Corridor Investigation for a 1.1-mile stretch of Riberia Street in downtown St. Augustine in advance of construction activities. Parcel Data Sheets summarizing historical, current, and regulatory information obtained during this investigation were prepared for each of 99 parcels. Aerial photographs, city directories, interviews, and Property Appraiser’s information were used to identify mixed undeveloped land, residential property, and commercial property back to 1859.

Geophysical Investigation for UXO

A Phase I ESA was completed on a 315-acre undeveloped property in St. Johns County, Florida, formerly owned by the US military in the 1940s and was used by the Naval Air Advanced Training Command during World War II for an outlying airfield in conjunction with training operations at the Jacksonville Naval Air Station. A Limited Geophysical Investigation was conducted to determine the presence or absence of buried metallic ordnance (UXO) within the center of a feature of interest. No unexploded ordnance or ballistic-type material was identified during the investigation. All excavated anomalies were found to be associated with barbed wire fencing and metal fencing material (nails, strapping bands, railroad tie/steel girder, etc).

Expedited Assessment & Cleanup

Matanzas initially completed a Phase I and Phase II ESA at a property located in the growth path of new port development projects in Jacksonville. Contamination at the site required assessment and cleanup under the state’s Petroleum Contamination Cleanup Criteria. Given the client’s desire to bring their project on-line as quick as possible, Matanzas proposed to complete assessment, remediation, and closure activities within a year. Prior to initiating field activities, Matanzas sought and obtained by-in from City of Jacksonville environmental regulators. Within an eight month period Matanzas assessed the contamination, completed source removal activities, completed two consecutive quarters of groundwater monitoring, and submitted a combined Contamination Assessment/Source Removal Report to the City of Jacksonville.
