The Boston Groundwater Trust (BGwT) was established in 1986 by the Boston City Council with the primary objective of monitoring groundwater levels in specific city sections. The focus areas are those where the stability of building foundations, which are supported by wood pilings, is at risk due to low groundwater levels. The accompanying video (viewed best in desktop mode) visually represents a typical row house in a filled land area in Boston. These houses are supported on wood piles capped with granite blocks, showcasing the traditional foundation method used from the 1800’s to the early 1920’s. It's evident that when the groundwater level remains above the tops of the wood piles, they can maintain their strength and effectively bear the weight of the building. However, a decline in the groundwater level leads to the exposure of wood piles to air, initiating a process of decay that compromises the stability of the building, ultimately posing safety hazards.
