Abstract

Soil chemical analysis has been one of the most active and promising areas among the recent innovations in household archaeology. Ancient inhabitants unintentionally left chemical imprints of daily activities, providing important clues as to past practices and space use, which are difficult to judge from artifactual data alone. Soil chemical testing in the Maya region is particularly promising given the highly calcareous nature of the soils derived from the carbonate geology of the region, as calcium ions and soil alkalinity render phosphorous, iron, and other metallic ions insoluble. This paper reports the results of soil chemical analysis of modern and ancient residential structures at the archaeological park of Aguateca, Guatemala. An ethnoarchaeological study of the guards' living quarters and archaeological data from rapidly abandoned Classic-period residences provided opportunities to refine an understanding of the relationship between human activities and soil chemical signatures. Both cases exhibited good correlations of high phosphorous concentrations in soils with food processing, consumption, and disposal. High levels of heavy metals in the modern structures probably derived from the filing of machetes and the disposal of flashlight batteries, whereas the use of mineral pigments and craft activities appear to have contributed to the concentrations of these elements in archaeological contexts.
