    "Description: This is Arcata's green waste compost dump Justification: Green waste materials may be dropped off here to continue the decomposition process so as to eventually be sold as usable nutrient rich compost. Issues: The actual method of composting is quite simple as it naturally occurs with or without help. Wes Green's appears to be tending to both active and passive compost heaps. Active compost will decompose quicker and turn into nutrient rich soil sooner than will passive composting piles. For more info see "notes." Location: It is owned by Wes Green's and is located on West End Road at their site within the Arcata city limit. "

    "A treadle pump is a human-powered Pump designed to lift water from a depth of seven meters or less. A Treadle is a lever device pressed by the foot to drive a machine, in this case a pump. The treadle pump can do most of the work of a motorized pump, but costs considerably less (75%) to purchase. Because it needs no Fossil fuel (it is driven by the operator's body weight and Leg Muscl]s), it can also cost less (50%) to operate than a motorized pump."
