It presents site maps and clam sampling, hypotheses (storm sewers, groundwater, buried high-Hg deposits, and floodplain sloughing), simple mixing math, geomorphic deposition (~1 cm/yr), planned sampling, and recommends EPA Method 1631 analysis.

The PDF is a slide presentation with maps, photos, and hypotheses but contains no clear author or publication date. WordPress upload metadata was not used.
