| With the acidulation of the leachate with sulfuric acid, the vanadium is precipitated as sodium hexavanadate. |
| The treatment of leachate and the safe disposal or even use of landfill gas are components of an environmentally sound waste management policy. |
| The leachate was separated from the solids by centrifugation, and the dissolved polonium isotopes in the liquid were plated spontaneously onto a silver planchet. |
| Many of these are soluble in water and become dissolved in any surplus moisture in the landfill site to produce a liquid mixture termed leachate. |
| All landfills, including those not in use, produce landfill gases and leachate, or water that has permeated the surrounding soil. |
| The residual material no longer produces methane, and leachate is much reduced. |
