What are Leak Detection and Repair Services (LDAR) at Element?
LDAR services involve systematic monitoring to detect and repair leaks of Volatile Organic Compounds (VOCs) and Volatile Hazardous Air Pollutants (VHAPs) from industrial equipment. Element's approach combines advanced detection technologies with digital tracking systems, delivering comprehensive emissions monitoring across your facility while minimizing operational disruption.

What can Element offer you for LDAR services?
Components and materials we test
Components and materials we test
We monitor all potential leak points across your industrial facility, including valves, connectors, and process equipment. Our systematic approach ensures comprehensive coverage of VOCs and VHAPs emissions sources, with particular focus on components prone to major leaks that could impact compliance or safety.
Key services offered
Key services offered
Our six-step LDAR methodology includes component identification, leak detection procedures, monitoring processes, results reporting, repair tracking, and comprehensive record keeping. We develop site-specific procedures and customize leak thresholds based on your facility's unique requirements and compliance needs.
Our initial setup creates a foundation for long-term efficiency. We help streamline your processes, minimize overheads, and optimize maintenance schedules. By systematically identifying non-leaking components, we can reduce monitoring frequency where appropriate while maintaining compliance standards. This approach helps you achieve both environmental and operational excellence.

Frequently asked questions
What happens after a leak is detected?
Components exceeding 2.5% of the leak threshold are identified for repair. Operators follow first-step repair procedures, with extensive repairs scheduled during predetermined maintenance periods. All actions are documented in the electronic log.
How can reducing leaks improve profitability?
By identifying and fixing leaking components, you can reduce product loss while improving process efficiency. Our monitoring helps target specific types of emissions, allowing better planning and cost management.
Can monitoring frequency be adjusted?
Yes. Once we establish a baseline, components that consistently show no leaks can have their check frequency reduced. All changes are documented in the electronic register to maintain compliance.
