| True, leachate can lead to many lesser health problems and environmental effects that the EPA did not assess. |
| Sludge in the landfill ferments and produces polluting leachate and greenhouse gases. |
| All landfills, including those not in use, produce landfill gases and leachate, or water that has permeated the surrounding soil. |
| It also provides a means of collecting most of that leakage and therefore is a second leachate collection system. |
| The leachate was separated from the solids by centrifugation, and the dissolved polonium isotopes in the liquid were plated spontaneously onto a silver planchet. |
| The residual material no longer produces methane, and leachate is much reduced. |
