Description Based on observations from digesting cookware during an ongoing study, Washington State Department of Ecology will take additional steps to investigate challenges in preparation methods for metals in cookware. This addendum to Quality Assurance Project Plan: Lead in Cookware Preparation Method Development Study describes these steps. The purpose of this study is to look at the same cookware products digested using EPA Method 3052 with the addition of hydrofluoric acid.
