Our Research

Assessed the risk of pollution from farming at an organic farm through the air pathway.

Created the Monte Carlo FEMS model to evaluate breathing exposures from agricultural pesticide use, which the U.S. Environmental Protection Agency approved.

Completed extensive urban air quality studies that generally involved emissions assessment, dispersion modeling, and model performance evaluation in locations such as Ostrava, Czech Republic; Katowice, Poland; and Jakarta, Indonesia. The EPA project “Breathe Easy Jakarta,” which we completed, is generally detailed here: 02/23/2010: U.S. EPA Partners with Indonesia to Improve Public Health in Jakarta.

Evaluated lead amounts at a primary Superfund site in the western U.S., generally focusing on breathing and surface lead exposure.

Conducted over 60 large Air Quality Studies to measure airborne emissions. These studies examined emissions from pesticide applications, covering all primary agricultural fumigants, and included monitoring and analysis methods.

Evaluated airborne exposures during the cleanup of a contaminated waste area at a federal site.

Developed the RISKMANpro™ modeling system to calculate emission rates generally related to accidental chemical releases.

Modeled chlorine levels resulting from an accidental release at an industrial site in the Southeastern U.S.

Conducted modeling to assess air exposures related to a barge accident causing emissions of volatile organic compounds.

Sullivan Environmental also performed dispersion modeling analyses for a coal-fired power plant in the Washington D.C. area, especially AERMOD and CALPUFF modeling and data evaluations.

Analyzed a secondary lead smelter, focusing on airborne and deposited lead evaluations.

Studied odor levels near a waste transfer facility, chiefly including sample collection and dispersion modeling to calculate dilution rates by distance. 

Correspondingly, assessed odor distribution around a manufacturing site. Furthermore,

Analyzed pesticide amounts from federal lands in the Western U.S. Additionally,

Additionally, we completed dispersion modeling for a new secondary lead smelter in South Carolina, including emissions assessment and optimal air quality monitoring locations. Furthermore,

Additionally, estimated residential airborne exposures to heavy metals in a city from the 1940s.

Performed noise monitoring and modeling analysis chiefly using Sound Plan.  This included current conditions and potential mitigation options for a significant commercial facility in Virginia.

Importantly, Sullivan Environmental developed software to enhance modeling analysis of NO2 emissions from traffic and gas stations, with calibration based on various atmospheric factors, generally using the EPA MOVES model for NO2/NOx ratios and AERMOD for dispersion modeling.
