From Wikipedia, the free encyclopedia
Non-aqueous phase liquids, or NAPLs, are organic liquid contaminants characterized by their relative immiscibility with water. The most common examples of NAPLs include petroleum products, coal tars, chlorinated solvents, and pesticides.[1] NAPLs can be released into the environment from a variety of point sources such as improper chemical disposal, leaking underground storage tanks, septic tank effluent, and percolation from spills or landfills. The movement of NAPLs throughout the subsurface environment is complex and difficult to characterize, but important to understand when determining appropriate mitigation strategies.
This is the sandbox page where you will draft your initial Wikipedia contribution.
If you're starting a new article, you can develop it here until it's ready to go live. If you're working on improvements to an existing article, copy only one section at a time of the article to this sandbox to work on, and be sure to use an edit summary linking to the article you copied from. Do not copy over the entire article. You can find additional instructions here. Remember to save your work regularly using the "Publish page" button. (It just means 'save'; it will still be in the sandbox.) You can add bold formatting to your additions to differentiate them from existing content.
