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 />Target analyte response was below the laboratory defined negative threshold. <br />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 />(2) Sal, Sludge, and Plant matrices for Inorganic analyses are reported on a dry weight basis. <br />(3) Animal matrices for Inorganic analyses are reported on an 'as received" basis. <br />(4) An asterisk in the "XQ" column indicates there is an extended qualifier and/or certification qualifier <br />associated with the result. <br />For a complete list ofACZ 's Extended Qualifiers, please dick: harn x�% �-,t .acz.cum•piibliccxtqualli,t.odf <br />REPIN11.10.10.01r Page 4 of 9 <br />
