A probe includes a substrate and a tetragonal structure disposed on the substrate that has four end points. The perishables are grouped based on the use-by-date and a quantity of at risk perishables are determined. In an in-situ system for remediating sediments in underwater sediment beds that are contaminated with and other contaminants, the contaminated sediments are treated with ozone with an ozonator conveyed over the sediment bed to mix the sediment with the ozone.
