Field Services

Truesdail’s Field Services staff provides pre-scheduled sampling and pre-notification. Sample collection by experienced, well-trained personnel ensures sample integrity, representative samples, and valid results for compliance monitoring.

Our field personnel are fully trained and have the experience to deal with unexpected and difficult situations as well as the routine. Safety is our number one concern. Our field personnel are trained for confined space entry and Level C personnel protection can be provided.

We can provide DOHS report forms, Sanitation District report forms, NPDES permits, LACSD Surcharge reports, custom reports, and PC data packages.

Our Field Services Staff routinely installs flow/pH monitoring equipment, pH control equipment, computer connections, and wires (construction and installation).
