An urban residential lot typical of those found
in the Greater Boston LSY study site.
- The 30' by 60' wood frame home is located on an approximate 1/8th acre lot.
- The wood frame structure was likely constructed in the early half of the 20th century.
- Visual evidence suggests that this house has been painted many times since its construction.
- The house currently is sided with aluminum siding.
The color codes on the map designate average lead in soil concentrations, based on in-situ XRF measurements.
- Note that the majority of the property falls into the yellow range (average soil concentration between 400 and 2000 ppm).
- Higher average concentrations of lead in soil are found adjacent to the wood frame structure.
- Small paint chips in the soil are usually associated with the highest soil lead values.
- Although the house is covered with aluminum siding, elevated levels of lead remain in the soils adjacent to this building.
