One of EnvironChem Engineering Consultants (ECE) main areas of
expertise is in the application of environmental models. We are dedicated to the application of
innovative and cost effective solutions to environmental problems. Our services range from simple
screening level assessments to complex multi-dimensional applications, for the purposes of:
- Evaluation of environmental data
- Prediction/evaluation of environmental spills
- Evaluation of thermal discharges/temperature modeling
- Storm water hydraulics and flooding
- Evaluation contaminant transport
- Determination of maximum ground-level concentrations
- Calculation of effective stack height
- Particulate distributions, terminal or settling velocity
- Deposition of particulate from stacks
- Estimation of emission rate from monitoring data, emission factors, and mass balance
- Modeling of methane emission from landfills
- Modeling of atmospheric and noise impacts from mobile sources
ECE identifies and applies innovative computer models and integrated database management systems customized for clients for pollutant
source assessment, monitoring, design of pollution control equipment, and remediation activities. Also, the firm offers high quality training
for environmental professionals interested in understanding the full impact of computer modeling on the environment and natural
resources.
All in-house models have been purchased from various commercial vendors or compiled from public domain sources such as EPA, USAF,
API, Ontario MEE, Alberta MoE, etc. Most of programs are designed for MS-DOS platform, but there are also several programs written for
MS Windows or Unix platforms. Our powerful, up-to-date PCs connected with digital post-processors, color printers, scanners, etc.,
assures that all projects are of the highest professional standards and are completed on time, on budget, and to the client's total
satisfaction.
