Pb. Atomic Number 82.
Divorced from its placement on the periodic table, the element finds itself exposed in a garden, nestled between bioretention and a bus depot.
Researchers came into to town and made the lead in the soil ledgible and knowable. Soil was tested and this dirt pile was labeled a hot spot. The soil, through analysis in a lab, became suddently differentiatiated from it's environment. Speculation on the origins of now changed earth ran rampant. Yes, the lead is a chemical legacy, but from where or from whom? Perhaps a long shuttered paint store was dumping its expired wares behind a shop. The chemical legacy proves persistant, but its origin story has degrated with time. Would there be any purpose to tracking the origin of the spot? Are there even actors to hold accountable? Should resources be spent to remediate the small environmental harms when others lurk that are larger in scale in and in affect?
While we ponder, the site is marked by a material more durable than our more human legacies. A concrete marker, or bench (depending on your tolerance for risk), tells a visitor of a history bound the earth. To intervene, the site is covered with dirt, a sign cautions the curious to resist the urge to disturb. To remediate this spot would take time, money, and expertise when all those resources are in short supply. Instead, the area is stewarded to make visible its contents. A delightfully perverse cue to care, inviting disuse and intentional avoidance. Let the earth lie.
