} <br /> Page 4 <br /> -- Turbidity <br /> Nitrate and Ammonia <br /> All samples will be collected in such a manner as to minimize the <br /> volatilization or oxidation of a sample due to agitation during <br /> transference from pump or bailer to sample container. When a <br /> bladder pump is used for the collection of volatile compounds, the <br /> flow rate will be adjusted to provide a constant flow stream of <br /> approximately 100 milliliters/minute. After samples for volatile <br /> compounds have been collected, higher flow rates may be used, <br /> particularly if large volumes are necessary. The sampling flow <br /> rates will never exceed the flow rate during the purging process. <br /> \GWLEV <br />
