Reference: Findings and Recommendations for the Remediation...
The costs of remediating a site will vary depending on the concentration and distribution of the contamination, the size and layout of the site, and the remedial actions implemented. Table 6 presents cost estimates associated with each remedial option presented above for 1 acre of contamination that is assumed to be 1 foot deep (1 acre foot). These costs are based on the remediation of undeveloped farmland.
Remediation costs could rise dramatically for existing development due to difficulties associated with the movement of soil around existing structures, trees, pools and decks. In addition, the remediation of properties with existing development would not have the benefits of economy of scale associated with undeveloped land. |

$50,000- $100,000 Remedial Option Cost per acre-foot
- Low: $50,000 ÷ 43,560 = $1.15 /cuyd
- High: $100,000 ÷ 43,560 = $2.30 /cuyd
