E-waste can contain toxic metals, which, if extracted improperly, can cause health issues in humans. Area is dug out and lined to prevent groundwater contamination from leachate. Trash is dumped and covered with soil frequently. Newer landfills have a leachate-collection pipe built in the leachate is collected and treated to be released back into the environment.
