| The residual material no longer produces methane, and leachate is much reduced. |
| With the acidulation of the leachate with sulfuric acid, the vanadium is precipitated as sodium hexavanadate. |
| True, leachate can lead to many lesser health problems and environmental effects that the EPA did not assess. |
| Then they poured distilled water into the columns and captured this leachate as it flowed out the bottom into flasks. |
| All landfills, including those not in use, produce landfill gases and leachate, or water that has permeated the surrounding soil. |
| The treatment of leachate and the safe disposal or even use of landfill gas are components of an environmentally sound waste management policy. |
