Sampling
and Analysis Plan under PBMs
EPA defines PBMS (per performance-based measurement system) as a set of processes
wherein the data needs, mandates, or limitations of a program or project are
specified, and serve as criteria for selecting appropriate methods to meet those needs
in a cost-effective manner.

Environmental Systems
Management, Analysis and Reporting neTwork (E-SMARTTM)
General Atomics (GA) has developed an integrated environmental sensing and monitoring
system (E-SMART), which connects smart (microprocessor-controlled) sensors into
monitoring and control networks. This automated system offers many advantages for
characterizing and monitoring environmental contaminants and hydrological
parameters.

SCAPS
Heavy Metal Sensors
This project conducts side-by-side demonstrations and validations of three different
penetrometer-deployed sensors for real-time, in situ field screening of heavy
metals in soils: Fiber-optic Laser Induced Breakdown Spectroscopy (FO-LIBS),
Downhole-Laser LIBS (DL-LIBS), and X-ray Fluorescence (XRF).
