A field meter will be used to semi-quantitatively screen for carbon dioxide, ethane, ethene, hydrogen sulfide, <strong>and</strong> methane, <strong>and</strong> then any<br />
positives would be confirmed by the field lab (with selective confirmation by the fixed lab).<br />

Bolded values are greater than their respective PRGs.<br />
g/<br />
This RL is for separate analysis (in addition to TO-14A/TO-15) that will be performed at locations where 1,2,3-TCP is detected by the mobile lab.<br />
h/<br />
These RLs are for analytes analyzed via the TO-13 method at selected locations based on historical results.<br />
i/<br />
Oxygenates will be identified as Tentatively Identified Compounds by the Fixed Laboratory.<br />
j/<br />
This COPC is not on the DTSC/RWQCB list of analytes. The identification <strong>and</strong> quantification would be based on a one-point st<strong>and</strong>ard.<br />
