The City of Jacksonville is one of the oldest contracts held by OHC initiated in 1986 by Jacksonville Electric Authority and extended to cover the entire City.  OHC is responsible for conducting full environmental assessments on new sites and asbestos and lead surveys for all buildings scheduled for renovation and demolition, indoor air quality for all buildings, health and safety assessments, emergency response, mold and hazardous material remediation.

Environmental Assessments (EA): OHC conducted over a hundred site assessment for the downtown rehabilitation projects. OHC discovered a contaminated site from an old dry cleaning operation. The site assessment indicated a plume of DNAPL and dissolved chlorinated hydrocarbon. OHC designed a remediation system to include SVE and a multi-well groundwater  pump and treat system for plume containment.

Asbestos & Lead Testing and Removal: OHC has been responsible for the initial surveys and identification of all asbestos-containing material for the three (3) generating stations owned by JEA.  We were also involved in construction supervision and monitoring of asbestos and lead abatement for the demolition of Units 1, 2, 3 and 4 at the Southside Generating Station as well as Unit 2 at the North side Generating Station, asbestos abatement of the JEA plaza which includes three (3) buildings ranging from 10-16 stories and the 19 story central office building, Gator Bowl, Duval County Courthouse, Civic Center, and the Federal Reserve Building.  We are presently in the design stage for asbestos abatement of the entire City Hall, a 16-story structure.

Recently, the City tasked OHC to complete a Limited Contamination Assessment Report (LCAR) for the Highland site.  OHC removed an underground heating oil tank and discovered soil contamination; we recommended a specific course of action to include monitoring for natural attenuation and a monitoring only plan.  The plan was submitted to DEP for approval.  Upon approval, OHC installed five (5) wells to monitor the groundwater quarterly.  This was consistent with the state guidelines under the Petroleum Cleanup Participation Program (PCPP).  This project shows our dedication to providing very cost effective solutions to their environmental challenges.
