Air Testing Services

LEHDER's Emissions Testing Team is one of the largest and most experienced in North America and is recognized by several U.S. and Canadian regulatory agencies.

Although geared to provide high grade industrial emissions testing services for compliance purposes, many projects conducted by LEHDER are related to the development of process-specific pollutant emission factors for various inventories and approval applications. These large projects often involve simultaneous testing and the deployment of multiple field crews.

Our field teams are skilled, organized, cohesive, and professional.

Other air quality management services we offer include; Odor Investigations, Dispersion Modelling and Applications for Licenses, Permits and Certificates of Approval.

Industrial EHS Services

LEHDER provides a broad range of environmental, health and safety services to our industrial clients. These services include air quality management; industrial hygiene; indoor air quality and mould assessments; waste and hazardous materials classifications and property liability assessments and management.

Our Industrial Services Team of engineers, air dispersion modelers, industrial hygienists, scientists, project managers, information management specialists and technologists work together to provide innovative solutions to our client's most challenging issues.

One of the best examples of these innovative approaches is the LEHDER EHS Information Management Service (LEIMS). Industrial facilities today are faced with the challenge of collecting, storing, managing, and evaluating an immense amount of environmental, health and safety data. LEHDER developed LEIMS to turn this EHS data into accessible information. LEIMS provides a strong data management element for the air quality services we offer such as the development and management of source and emission inventories, air dispersion modeling and applications for Permits, Licenses and Approvals. On large properties or sites with multiple issues, LEIMS is used to ensure that the environmental data associated with environmental investigations or monitoring programs is properly managed.
