The Potential Impact of Forest Loss on Drinking Water Treatment Costs in the Southeastern US
Summary
Estimates how projected forest loss could increase drinking water treatment costs across the southeastern United States, linking land use change to public infrastructure costs.
Abstract
Forests play a critical role in protecting drinking water quality by filtering pollutants and reducing sediment loads. This study estimates the potential impact of projected forest loss on drinking water treatment costs for public water systems across the southeastern United States.
Why It Matters
The connection between forest cover and water treatment costs has implications for:
- Municipal water utility budgets and rate planning
- Cost-benefit analyses of forest conservation programs
- Watershed protection investments
- Climate adaptation planning for water infrastructure
Key Findings
- Forest loss in source watersheds is projected to increase water treatment costs
- The southeastern US is particularly vulnerable due to rapid development pressures
- Results quantify the economic value of forests as natural water filters
- Findings support investment in watershed protection as a cost-effective alternative to treatment plant upgrades
