Abstract
This study quantifies the magnitude and spatial-temporal persistence of home value losses associated with a chemical spill in the Elk River using difference-in-difference, spatial regression techniques. Results suggest homes within 3 miles of the spill experienced a value loss, with the largest effect on homes within one mile of the spill. Homes beyond 3 miles experienced no significant effect. The loss in value affected prices for years after the contamination was remediated. Homes within the water utility service area experienced a significant increase in value following the spill, which may reflect public value of water quality monitoring by a utility.
