1. A polycrystalline diamond compact, comprising:
a substrate; and
a polycrystalline diamond body including an interfacial surface bonded to the substrate and a working surface generally opposing the interfacial surface, the polycrystalline diamond body including a first leached volume extending inwardly from the working surface and a second volume at least proximate to the substrate that includes at least one interstitial material therein, wherein the first leached volume is substantially free of a residual amount of acid, wherein the polycrystalline diamond body exhibits a concentration of anions of one of 2 parts per million to 3 parts per million or 1 part per million to 2 parts per million, and wherein the polycrystalline diamond body exhibits a pH of about 5 to about 9.
