The associated value is an estimated quantity. <br />H Analysis exceeded method hold time. pH is a field test with an immediate hold time. <br />L Target analyte response was below the laboratory defined negative threshold. <br />U The material was analyzed for, but was not detected above the level of the associated value. <br />The associated value is either the sample quantitation limit or the sample detection limit. <br />Method References <br />(1) <br />(2) <br />(3) <br />(4) <br />(5) <br />Comments <br />(1) <br />(2) <br />(3) <br />(4) <br />(5) <br />EPA 600/4-83-020.
