Most cases of groundwater contamination by agricultural chemicals have been caused by improper storage or mixing and loading chemicals. For this reason, agricultural chemical storage and handling practices have been targeted by federal and state legislation across the United States. To satisfy the proposed regulations, dealers and applicators are encouraged to construct safe chemical storage and mixing/loading facilities with secondary containment.
Why Do We Need Storage and Handling Facilities?
Most cases of groundwater contamination by agricultural chemicals have been caused by improper storage or mixing and loading chemicals. For this reason agricultural chemical storage and handling practices have been targeted by federal and state legislation across the United States. To satisfy the proposed regulations, dealers and applicators are encouraged to construct safe chemical storage and mixing/loading facilities with secondary containment.
The purpose of secondary containment is to contain, recover and reuse spills and rinsate. It is a form of insurance, providing environmental safety by preventing spills from entering the soil, surface water and groundwater. Secondary containment also reduces legal liability of the owner and associated costs of cleaning up a contaminated site. A well-managed and designed facility reduces worker and public exposure to agricultural chemicals.
Groundwater contamination and worker exposure can occur by: 1) unsafe storage practices, 2) large accidental spills, 3) periodic unrecovered spillage of small amounts of pesticides when mixing and loading in one location, 4) inadequate cleaning of spray equipment, 5) leaking equipment parked on site, 6) improper disposal of excess spray solutions or rinsates and 7) improper disposal of containers and other "waste" materials.
