Mission
The 20 foot long “fifth wheel” trailer is configured as a laboratory for analytical services in the field.
The unit serves as a mobile platform for an array of instrumentation in support of numerous Agency activities.
Control measures are in place to ensure data quality.
4
Operations
Installed generator supply the necessary electricity. Heating and air-conditioning allow for year round use.
The Region 6 Lab in Houston serves as the base of operations and as a full service fixed base laboratory is able to provide confirmation analysis. Chemists & biologists from Regional Accredited lab staff the mobile laboratory.
In addition to analytical equipment, the unit has: Mounting bracket for weather station to measure wind speed,
direction, ambient temperature, and humidity
Mounted satellite dish for data transfer from the remote site

Mobile Lab Advantages
Exploratory Analyses INFICON (Hapsite)
Metals by XRF
Faster Results Methods are streamlined
Short TAT (time critical)
In situ testing vs preservation & shipping
Efficient Multiple analyses at station/grid
Eliminates unnecessary samples
8
Field Operation Advantages
Provides real time information resulting in an enhanced operation
Fluidized decision making
Communication – Satellite service and Wireless Network
Sampling – Covered area for labeling, chain-of-custody, and paperwork
Storage – ability to transport coolers, bottles, SUMMAs, ice, and sampling equipment
Logistics – Staging point for Region 6 chemists and field personnel
9
Mobile Lab Limitations Sensitivity
XRF vs ICP/MS
Analytical QC IDOCs, MS/MSD, LRB, etc.
Less definitive – confirmation required
Variability No new Contaminants of Concern
Data Review & Labeling
Dependent Shore power or diesel generator
Permit requirement to enter facility

Quality Assurance
Analytical Method QC Volatiles - Method 8260
• ICAL, CCV • Lowest point = RL• Blanks• Surrogates
Metals - X-ray Fluorescence, Niton XL3t – SW-846 6200
• Calibration - Intrinsic (standard less) or empirical (regression)
pH Measurement – 3 point ICAL, 1 point verification
Seta flashpoint – ASTM 3828 – diesel & p-Xylene standards
Coliforms – positive, negative & blank controls

Quality Assurance
QAPP Surveillance - designed for second stage fixed base lab testing Disaster Response/post incident
DQO – General Requirements Surveillance/Enforcement
• Generation of laboratory data of Tier I quality. Data must be of rapid TAT for the time critical facility evaluation. Quantitation limits should be less than or equal to the action limits. Neither secondary reviews nor labeling is required before reporting. Electronic reporting is not required.
Disaster Response/post incident• Generation of laboratory data of Tier I quality. Data must be of
rapid TAT for the time critical onsite event. Quantitation limits should be less than or equal to the action limits. Secondary review is required and labeling is not required before reporting. Electronic reporting is required.
