The Arkansas Groundwater Monitoring Program works to prevent groundwater contamination from agricultural chemicals and respond effectively if contamination occurs. Its core goal is to:
- Protect public health and welfare
- Preserve terrestrial and aquatic life
- Safeguard the environment
- Support agriculture and industry
- Maintain long-term economic health
Preserving groundwater quality is more cost-effective and sustainable than attempting to restore it after contamination.
Monitoring Approach
Since 2004, the Department has monitored groundwater in vulnerable areas (regions with high agricultural activity and pesticide use) using an EPA-approved Pesticide Management Plan. This plan includes coordination with the Arkansas Department of Health to determine appropriate response actions if contamination is confirmed.
Voluntary Sampling Program
The Groundwater Program offers free laboratory testing of agricultural well water as a voluntary service to farmers and applicators.
Benefits:
- Detect potential pesticide contamination
- Ensure pesticides are used safely and according to label directions
- Help producers prevent environmental and regulatory issues
Contamination Response
The program addresses both:
- Point source contamination (from a specific site, such as a spill)
- Nonpoint source contamination (from widespread agricultural practices)
When a pesticide is detected, the Department investigates the source and helps guide corrective actions.
Prevention Through Best Management Practices (BMPs)
Using BMPs is the most effective way to prevent groundwater contamination. While BMPs cannot guarantee contamination won’t occur, they serve as critical tools for:
- Reducing pesticide runoff
- Protecting water sources
- Promoting responsible pesticide use
