Dump him!
The best method is to dig out the roots.
For each chemical a specific method od of storage is recommended.
Dig, weed, add manure
when products are not recycled they are taken to the dump to either break down, or they dig a massive hole and put the rubbish in.
dig, dodge, drive, dump, dice, deliver, dance, dab, decorate, dive, descend (how many do you want?)
You can contact your Department of Natural Resources. They may be willing to dump some fish into it if you wish. They can tell you what the requirements are.
Possibly, if you are being aggressive with the excavator, setting the parking brake would take tension off the transmission though.
One method would be to direct a stream of water into the location where you plan to dig the hole and allow erosion to dig the hole for you. If you could manage to pressurize the water, it would cut the time significantly, but it will still take a while. A lot of this will depend on how hard the ground is that you're trying to dig into.
To give an example.... when you pave something such as a racetrack, you're at a very steep angle which would cause a dump truck to tip over once its bed was raised into the air. In many cases, the bed may not even have to be raised for this to happen. One method to allow dump trucks to dump into a paving machine on such surfaces is to have cranes hook to the beds and chassis of the dump truck in order to prevent them from tipping over. Which is fine, if the truck has a bed which won't be damaged by the hooks. However, many dump trucks do not, and their beds may be susceptible to damage from having a crane hooked to it - especially in the case of dump trucks which have lightweight aluminum dump bodies, rather than steel dump bodies.
Getting a dump truck, filling it with baking soda and dumping the soda into the lake.
A dump truck is simply a truck with a dump body - it could be a side dump, belly dump, or end dump. An end dump dumps out of the rear. "End dump" is generally used to refer to tractor-trailer end dumps, while single vehicle end dumps are generally just referred to as "dump trucks".
