The California Bay-Delta Authority currently has a mercury program, the CALFED Mercury Project that assesses the ecologic and human-health impacts of mercury in the bay-delta watershed. Past research includes assessments of bird mercury exposure, analysis of the effects of wetland restoration on methyl-mercury production, and studies of the geochemical composition of mercury-rich mineral deposits. Much mercury research in the CALFED program has focused on the Cache Creek watershed because of its large mercury contribution to the Sacramento River watershed.
