Water quality will remain a top priority during remediation and construction at The Heights. At this time, there are no public safety concerns. Our tests show that contamination is shallow, going no deeper than 6″ to 36″ from the surface.
Furthermore, mercury found in soil, resulting from fungicides, is relatively insoluble and does not typically spread to groundwater. At this point, we have not found any evidence of mercury in the groundwater.
We will take extra precautions in case of soil erosion. Protections will be in place around the perimeter of the property should there be heavy rains.
