Environmental Testing For Dissolved Gases
Pace® offers a range of specialized services for analyzing dissolved gases in water, including methane, ethane, ethene, propane, and acetylene. Using state-of-the-art laboratory equipment and industry approved methodologies, our accurate and reliable analysis for these gases helps our customers adhere to environmental standards and industry regulations.
What Are Dissolved Gases?
Many gases are water soluble and can impact environmental ecosystems and public water systems in both good ways and bad. Common dissolved gases that can have a negative impact include methane, ethane, ethene, propane, and acetylene. These gases can be released into the environment through industrial activity. Methane can also be produced by anaerobic decomposition of organic matter in water. While dissolved gases can be detrimental to human and ecosystem health, the greater concern is often the risk of fire or explosion.
Who We Serve
Pace® provides dissolved gases testing for a wide variety of industries and business concerns. Here are some common types of clients we help monitor potential contamination, ensure remediation efficacy, and comply with environmental regulations.
The water produced as a byproduct of oil and gas exploration can contain several types of dissolved gases, such as methane, ethane, propane, and butane. In large enough quantities, these gases may present a risk of explosion and fire.
Landfills may produce large quantities of methane, a byproduct of the anaerobic decomposition of organic matter in water. A flammable gas, methane can be an explosion risk. Exposure to methane can also lead to health problems such as fainting, fatigue, rapid breathing, memory loss, and impaired vision.
Dissolved gases can build up in public water systems, creating an explosion risk that threatens human health, public infrastructure, and the environment. In some cases, these gases can also have a negative impact on health and well-being.
Dissolved gas analysis is used to assess the extent of environmental contamination to rivers, lakes, and other water bodies, providing essential data for ecological studies and pollution control efforts. Dissolved gas testing can also be used to assess the efficacy of remediation efforts.
Dissolved Gases Testing
Pace® offers several test methods for dissolved gases testing in water. EPA Method 3810 is a static headspace technique used for extracting volatile organic compounds (VOCs), which allows for many samples to be screened in a relatively brief period. If dissolved gases are indicated, more advanced methods can be used to quantitate levels. EPA RSK-175 can also be used for determining the presence and concentration of dissolved gases in water samples. Finally, Pace® is participating in the interlaboratory study (ILS) for the development of a new method under ASTM (American Society for Testing and Materials).
Dissolved Gases Regulations
Dissolved gases analysis plays a crucial role in understanding and managing contaminated sites under laws such as the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and the Resource Conservation and Recovery Act (RCRA). Evaluating the presence and concentration of dissolved gases in groundwater enables the identification of contaminant sources, provides insights into the degradation or transformation of hazardous substances, and aids in assessing the overall risks to human health and the environment. Furthermore, dissolved gases analysis helps regulators and responsible parties monitor the progress and effectiveness of remediation efforts, such as natural attenuation or bioremediation strategies.
