Air Pathway Analysis assessing indoor and outdoor exposure potential supporting health risk assessment. Chuck Schmidt is an environmental consultant located in Red Bluff, California. He has expertise in measuring air emissions from area sources, including air pathway analyses (APA).
He provides a technical service which includes: studying the source, developing a technical approach, writing work plans, conducting testing, qualifying the air emissions data, and reporting the air emissions from the area source.The assessments include area sources in any industry or on any site, and the data generated serve a variety of project needs.

While ATSM recommends soil gas as an ideal reconnaissance tool and screening technique, soil gas monitoring does not provide repeatable quantitative information over time due primarily to the dynamic nature of phase equilibria in the vadose zone and secondarily to unavoidable inconsistencies in sampling practice.
USEPA Flux Chamber Used to Measure Area Source Emissions from Dry Lot and Flushed Lane Dairies, Poultry Facilities, Land-Applied Manure on Cropland, and Other Agricultural/Animal Husbandry Applications. Air emissions from the agriculture industry in Southern and Central California (dairy farms, egg ranches, manure drying beds, manure treatment, manure composting), has become a focus of regulatory interest.
USEPA Flux Chamber Technology for Assessing Unit Process and Site Emissions from Municipal Wastewater Treatment, Including Wells, Headworks, Primary Treatment, Secondary Treatment, Channels, Clarifiers, Overflow Lagoons, and Outfall. We have been conducting air emissions assessment from municipal wastewater treatment (WWT) facilities for many years now.
USEPA Flux Chamber Technology Applied to Area Sources Not Commonly Measured or for Species that Present Unique Challenges. This section is meant to show the versatility of the USEPA flux chamber measurement technology, but it's really more for fun. Most of the time we are assessing emissions from hazardous waste sites or permitted industrial sites, but not all the time.
Our team had the privilege of participating in a research and development program conducted for the San Joaquin Valley Air Pollution Control District (SQVAPCD). This program was part of the Technology Advancement Program (TAP) and our involvement included conducting the air emission assessment of a positive aerated static pile (+ASP) pilot-scale compost technology employing a biofilter layer (BFL) as a control technology (Photo 1).
