Project Highlights since 1996 

Listed Below are just some of the field projects that KASSAY has been involved with since 1996.  Included are term projects that represent some of the interesting applications where we have used op-ftir technology.  Not included are ongoing projects and/or servicing of clients with fixed installations.

 

 

Client:             GEI Consultants, Winchester, MA                                 July – 2002

Project:            MGP site perimeter monitoring.

 

Utility companies are in the process of cleaning up thousands of MGP sites throughout the northeast.  Many local communities have expressed their concern about the off-site impact of air emissions generated from remedial activities.  KASSAY participated in a feasibility study sponsored by EPRI to assess effectiveness of several air monitoring technologies.  The op-FTIR was highly successful in demonstrating the capability to detect and quantify contaminants of concern in real time. 

 

Client: University of Medicine and Dentistry   August – October 2001 UMDNJ New Brunswick, NJ 

 

Project:            Ambient air monitoring at the Joint Meeting Edward P. Decher secondary wastewater treatment plant, Linden New Jersey

 

VOC and HAP emissions from the treatment of municipal wastewater is usually derived from estimates based on periodic wastewater sampling.  In an improvement effort, KASSAY performed a series of direct op-FTIR air measurements downwind of primary, aeration, and chlorination basins.  Consistent with confirmatory sampling during the project (TO-14), op-FTIR was determined to be a viable technology for this application (TO-16).

 

Client:              MSC, Freehold NJ                                            July – October 2001

 

Project:            NYC Wastewater Treatment Plant 26 Ward Plant  - H2S Emission estimation in support of plant upgrade

 

Further refinement of the prior years work at Bowery Bay (see Bowery Bay Project) included use of two tracer gases at separate distances.  The multiple tracers allowed for direct estimation of vertical dispersion modeling coefficients.  In addition, textbook atmospheric stability class selection could be eliminated.  KASSAY fielded and monitored multiple tracer gas and op-FTIR measurements through various meteorological conditions at the 26 Ward WWTP. Data was used to develop unique sigma-z curves for each measurement event, further refining the dispersion modeling.

 

Client:              Nepera, Inc. , Harriman NY                                          April 2001

 

Project:            Controlled tracer release at chemical plant

 

In response to community and regulatory concerns, it was suggested that the installed op-FTIR fenceline monitoring equipment be challenged with tracer gas.  KASSAY staff created then implemented a work plan to release tracer gas at three plant locations in order to assess the installed op-FTIRs ability to intercept plumes.  The study aided in determining plume capture and op-FTIR reflector locations under several wind directions.

Client:              MSC, Freehold NJ                                                    July – October 2000

 

Project:            NYC Wastewater Treatment Plant Bowery Bay  - H2S Emission estimation in support of interim plant upgrade refined air quality compliance assessment

 

Under certain scenarios, models suggest that Hydrogen Sulfide (H2S) emissions at the plant could reach a level requiring expensive emission controls. To better understand that potential, a more refined evaluation was recommended by the NYDEP.   KASSAY provided op-FTIR and Tracer gas measurements over various meteorological conditions at separate locations within the plant. Data was then used to generate site-specific vertical dispersion modeling coefficients which reduced conservatism in prior modeling.

 

Client:              AIL Systems, Inc.  Deer Park New York                       March  2000

 

Project:            Testing AIL’s op-FTIR air monitor in EPA’s Environmental Technology Verification (ETV) Program.

 

AIL Systems, Inc. (now EDO) a commercial manufacturer of op-FTIR spectrometers became the first op-FTIR vendor to participate in EPA’s ETV program.  As part of its advanced monitoring systems pilot, Batelle was the designated EPA coordinator for the open-path verification tests.  KASSAY was contracted to carry out the test/QA plan and op-FTIR collection & analysis of the three test gases.  Comprehensive tests were performed over a week at AIL’s test site in Deer Park, New York.  AIL became the first op-FTIR to successfully pass verification.

 

Client:              MSC, Freehold NJ                                                  February  - April 2000

 

Project:            Cytec Industries Inc. Wallingford CT  - Characterization of emissions from wastewater treatment plant.

 

Since emissions from industrial wastewater treatment is often estimated by modeling, overestimation of emissions can negatively impact compliance.  To gain a more accurate assessment of air impact, KASSAY provided on-site real-time op-FTIR and meteorological monitoring to characterize emissions from an aeration lagoon & equalization basin at the facility’s WWTP. Data was utilized to assess (and) improve the default based inputs of the TOXICHEM+ model.  Final data was used for assessment of annual emissions reporting and future emissions controls.

 

Client:              USAG APG – DOD, Aberdeen MD     March 1999–February 2000

 

Project:            Feasibility Assessment of Emissions Measurements using op-FTIR during emergency detonation of chemical munitions open-air detonations.

 

As part of the overall effort to improve the air monitoring protocol used during emergency detonation of waste chemical munitions, the APG Garrison Directorate of Safety, Health and Environment (DSHE) hired KASSAY to perform a phased feasibility assessment to evaluate the potential use of op-FTIR in providing better plume characterization of data. KASSAY successfully performed a comprehensive desktop analytical study on seven major chemical warfare agents, as well as potential tracer compounds for those agents.  Results were compared to existing techniques of agent measurement.

 

Client:              National Pork Producers Council (NPPC)   July –October 1999

Project :           Odor Solution Initiative

 

As a result of rapid growth in the pork industry, neighboring areas have increasingly complained of negative environmental impact including nuisance odors.  The National Pork Producers Council (NPPC) funded the  “Odor Solution Initiative.” Part of the study included the evaluation of the effectiveness of odor reduction engineering controls.   KASSAY Field Services, Inc. hired as an independent contractor and provided on site compound identification of farm emissions using op-FTIR spectroscopy at pork farms sites in Idaho and Missouri.  Emission data was also used to evaluate appropriate set-back distances.

 

 

Client:             City of Park Ridge, Illinois  - (adjacent to O’Hare Airport) September 1999

Project:            Measurement of Hydrocarbon emissions from airplanes at Chicago O’Hare Airport.

 

U. S. Aviation Watch (Alliance of Residents concerned with O’Hare) and the city of Park Ridge were interested in documenting the negative impact of airplane emissions as a result of fueling, taxiing, landing, and departing.  KASSAY spent several days on the property adjacent to O’Hare International Airport providing meteorological & op-FTIR data collection.  Data showed that op-FTIR could be employed as an effective tool for monitoring hazardous emissions resulting from airport activity.    

 

Client:              Apogee Scientific,Englewood CO        Jan – August 1999

 

Project:            Field support for PSE&G Hudson NJ plant ash supplementation test.

 

KASSAY supported Apogee in two EPRI sponsored tests.  Under Apogees’ direction, KASSAY staff visited the power plant on regular basis to monitor installed test equipment, perform ESP bag house sampling of ash, refill depleted supplies, and switch between sampling locations.

 

Client:              RJK Consulting, Cranford NJ    September – December 1997

 

Project:            FMC Pocatello ID - Emissions modeling of phosphene ponds

 

KASSAY staff performed a comprehensive modeling assessment to determine phosphene emissions from four settling ponds.  The modeling included reverse application of SCREEN, forward gaussian dispersion modeling,  and special handling of site-specific sigma-z vertical dispersion coefficients.   The modeling reduced the amount of conservatism when using classical textbook dispersion coefficients.

Client:              AIL System, Inc.           Deer Park New York    July 1997

 

Project:            Op-FTIR ozone measurements in Seoul, South Korea

 

As part of an intensive three week sales visit, KASSAY staff performed on-site demonstration at several interested South Korean industrial plants, as well as South Korea’s environmental agency.  KASSAY staff setup and collected op-FTIR measurements on the rooftop of South Koreas’ building for the National Institute of Environmental Research (NIER).  Op-FTIR measurements agreed with conventional measurements collected by NIER air physics division research team.

Client:              AIL Systems, Inc. (Now EDO Corp),  Deer Park New York        Jan 1997 - 1998

 

Project:            Superfund Perimeter monitoring during remedial activities at Lipari Landfill

 

As part of the PRP’s consent agreement, op-FTIR air monitoring was selected by the U.S. Army Corps of engineers as the air monitoring requirement during all soil disturbance activities.  Personnel at KASSAY staffed renewable projects at Lipari from 1990 –1998.  KASSAY staff were required to be on site for monitoring during any soil disturbance activities.  Near –real time gas concentrations were reported every ten minutes and compared to health based exposure levels at the site perimeter.
