• 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.
