Leveraging Sensors for Air Quality Monitoring

Understanding the Role of Sensors in Air Quality Monitoring

In conducting air quality monitoring work, Air Sciences has recognized the benefits of using non-regulatory supplemental and informational monitoring (NSIM) sensors in various applications. From assessing pollutant concentrations in neighborhoods to evaluating air quality near road construction projects, Air Sciences has used NSIM sensors to provide a cost-effective and flexible solution where traditional regulatory monitors may not be practical or necessary.

2024 PNWIS Conference

Air Sciences had a significant presence at the 2024 PNWIS Annual Conference, held November 12–15 in Eugene, Oregon. The conference is the signature event of the Pacific Northwest International Section of the Air & Waste Management Association. This year, Air Sciences was proud to be a platinum conference sponsor.

Taking a closer look at dry lakes and their impact

Lake desiccation has been happening for thousands of years; it’s not a new phenomenon. What’s new is the rate at which lakes are drying. For example, Lake Lahontan in the western United States dried over the course of 3,000 to 4,000 years due to natural climate change—but Lake Albert in eastern Oregon has shrunk dramatically over just two decades.

Helping sawmills maintain compliance

Sawmills in the Western United States have an intriguing history. As mostly European-descendant settlements of the 19th century American West forged deeper into resource extraction of wood to build homes and towns, sawmills were developed to process immense logs into usable lumber. Naturally, a power source was needed to propel the industry beyond the work of hand-sawyers. Technology used to power the mills included water turbines and steam engines, while boilers provided steam for a sawmill’s kilns.

Baghouse PM₁₀ Testing Frequency Calculator
(for Nevada)

This workbook calculates the frequency for how often a baghouse needs to be tested for PM₁₀ using the Nevada Division of Environmental Protection – Bureau of Air Pollution Control Testing Determination System (TDS). The TDS will be applied during all permit renewals and any revisions that include a baghouse. At this time, the TDS only applies to baghouses used to control non-combustion sources.
