Leached

Over time, the memories have leached from my mind.

The most valuable minerals have been leached from the soil.

Scientists say cilantro, a favorite ingredient in Mexican and Southeast Asian cooking, shows promise as a so-called biosorbent to mop up heavy metals that have leached into ground water from factories in many developing countries.

[T]he very wet winter will have washed much of the goodness out of the soil. Homemade compost and the load of manure we get from a friendly farmer may not be enough to compensate for what has leached from the ground.
