The scientists and engineers of Najarian Associates were retained by K. Hovnanian Co. to transform a highly contaminated brownfield site into a signature residential development on the Jersey City waterfront. Najarian conducted the environmental investigations, developed the Remedial Action Work Plan, obtained the NJDEP approvals and conducted remedial oversight for this redevelopment. Najarian also obtained NJDEP land use permits including a waterfront development permit and wetlands permits and a US Army Corps permit for wetland disturbance.

Najarian Associates was retained by the Middlesex County Improvement Authority (MCIA) to perform an environmental characterization of a 22.44-acre site in Milltown, NJ that was formerly occupied by the nation’s first Michelin Tire Company. The site is the subject of a redevelopment effort by the MCIA and the Milltown – Ford Avenue Redevelopment Agency, with support from the USEPA Brownfields program. Najarian completed a Preliminary Site Assessment (SA), Site Investigation (SI), and Remedial Investigation (RI) to completely characterize the site contamination. All of the investigations have been completed which included comprehensive soil, sediment, and groundwater investigations of the site, the adjacent Mill Pond and its watershed. The proposed remedial action for the site is a clean-fill cap, over which the site can be developed. The proposed development plan consists of both residential and commercial development.

In 2011, Najarian Associates was retained by PSEG Fossil LLC to conduct hydrothermal modeling to support the renewal of the NPDES Permit for the Bridgeport Harbor Generating Station. The primary goal of the study was to characterize the spatial and temporal distribution of temperature increases in Bridgeport Harbor due to the Station’s thermal discharges (“excess temperatures”) over a range of hydrologic conditions, hydrodynamic conditions and Station operations. These characterizations – along with a coordinated biothermal assessment – were used to determine whether the Station is protective of the Balanced Indigenous Community (BIC). To this end, Najarian designed a new field-monitoring program to support the model application, and analyzed the field data to characterize the local hydrography, hydrodynamics, climatology and spatial extent of the Station’s plume under prevailing conditions. To characterize non-surveyed conditions, a three-dimensional hydrothermal model (RMA-10) was adapted to the receiving waters. The model was calibrated/verified with the available and new field data. The validated model was then used to characterize the Station’s thermal plume for operating scenarios that were chosen to reflect primary factors that control the size, shape and movements of the Station’s plume. The resulting model outputs for each scenario were displayed in the form of plots and tabulations of spatial and temporal distributions of simulated excess temperatures. Model results were used to support a predictive biothermal assessment that demonstrated that the Station’s thermal plume is protective of the BIC.

Four Seasons at Smithville, New Jersey, Developed by K. Hovnanian Companies (www.khov.com), Designed by Najarian Associates (http://www.najarian.com). Located in Galloway Township, this large residential development is located adjacent to the Historic Village of Smithville. The project began in the 1980s when a CAFRA permit and other approvals were obtained for a large-scale development. NJDEP was sued over this permit, and Najarian Associates provided expert testimony and developed a stormwater model to support the NJDEP permit, which was upheld. The project then stalled in the late 1980s due to economic conditions and partially built neighborhoods were abandoned. The project was re-initiated in the mid-1990s by K. Hovnanian Companies with Najarian Associates retained to provide engineering and environmental services.

Najarian Associates conducted a hydrothermal modeling study to support PSEG’s Section 316 (a) Demonstration for their Mercer power generating station (the “Station”) located along the Delaware Estuary. a state-of-the-art, three-dimensional hydrothermal model (RMA-10) was adapted to the receiving waters. The calibrated/verified model was used to characterize the Station’s thermal plume for five operating scenarios that were chosen to reflect primary factors that control the size, shape and movements of the Station’s plume; River discharge, modes of Station operation (cycling vs. base load), differences between the discharge and intake temperature, and Station heat rejection rates. The resulting model outputs for each scenario were displayed in the form of plots of spatial and temporal distributions of simulated excess temperatures. This video shows the animation of simulated surface excess temperature in one scenario.
