Pesticides leak can be damage to environment
The residue from pesticides that leak from un-rinsed, discarded containers has the potential to cause significant damage to our environment. Therefore, containers should be rinsed immediately after use. If left in the container to dry, the residue becomes more difficult to remove. So, make it a little easier on yourself and go ahead and rinse it out right after you use it.
Since these containers have contained a commercial, hazardous material, it is illegal to dispose of them in landfills, recycling bins or incinerators. The only acceptable place to take them for disposal is to a hazardous waste facility. While this can be costly and time consuming, there is another option.
The most commonly used method is triple rinsing. When emptying a liquid pesticide from its container, wait until the flow reduces to drops. Continue draining for a minimum of 30 minutes after the drops start. Add the correct amount of water according to the size of the container: containers up to 5 gallons require an amount equal to at least one quarter of its volume; 30- to 55-gallon containers require a minimum of 5 gallons of water. Once water is added, secure the lid on the container. Smaller containers should be shaken vigorously. Larger containers should be rolled or tumbled in such a manner as to rinse all interior surfaces. Remove the lid and drain into spray tank. Continue draining for 30 seconds after drops start. Repeat this rinse process two more times. Replace lid and dispose of the container.
Pressure rinsing takes less time, but requires the purchase of a special nozzle. This rinsing method can be done as the pesticide is emptied into the spray tank. The special nozzle attaches to a garden hose and is used to puncture plastic and metal containers. Insert pressure nozzle by puncturing the lower side of the container. The nozzle produces a forceful spray inside the empty container and should be rotated to ensure that all interior surfaces are properly rinsed. Rinse for the length of time recommended by the manufacturer – usually 30 seconds. Container lid should be rinsed separately and placed back onto the container for disposal.
If properly prepared before disposal, the containers are then considered to be non-hazardous by the U.S. Environmental Protection Agency.
