<br />5 Should adverse water quality conditions occur due to the injection of oxidants, injections shall cease and those wells showing impacts will
<br />be monitored and bulk purged for the injection permit constituents of concern in Suite B as identified during the full-scale, until baseline is

<br />3 Dissolved metal analyses include Al, As, Ba, Be, Ca, Cd, Cr, Co, Cu, Fe, Hg, Mg, Mn, Mo, Ni, Na, Pb, Sb, TI, V, W, and Zn and are
<br />collected in laboratory-supplied non-preserved container, relinquished to the lab for filtering and preservation prior to analyses.
<br />4 Anions include bromide, bromate, chloride, nitrate, nitrate as N, nitrite as N, and sulfate
<br />FIELD SAMPLING
<br />3. In addition to the above sampling and analysis, groundwater elevation, electrical
<br />conductivity, DO, ORP, pH, and water temperature will be measured in the field each time a
<br />monitoring well is sampled. The sampling and analysis of field parameters is specified in
<br />Table 3.

<br />Field test instruments (such as those used to test pH and dissolved oxygen) may be used
<br />provided that:
<br />The operator is trained in proper use and maintenance of the instruments;
<br />The instruments are calibrated prior to each monitoring event;
