| The leachate was collected and then chemically converted to true saltpeter, potassium nitrate, by mixing it with a solution of potash. |
| The treatment of leachate and the safe disposal or even use of landfill gas are components of an environmentally sound waste management policy. |
| With the acidulation of the leachate with sulfuric acid, the vanadium is precipitated as sodium hexavanadate. |
| 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. |
| The residual material no longer produces methane, and leachate is much reduced. |
| Devices called lysimeters are sometimes inserted into the ground to collect subsurface water, called leachate. |
