If a well owner desires testing of a well, a certified laboratory should be hired to run the tests. Names of such laboratories can be obtained from your local health department. A landfill that reaches capacity is covered with a multi-layer, protective cap and planted with grasses and other ground covers. The owner must then conduct post-closure care, which includes monitoring of ground water, landfill gases, and leachate collection systems. Monitoring may be required for 30 years following closure.
Few restrictions exist on how the property over a closed landfill can be used.
Parks and golf courses are examples of possible uses. Construction of large buildings is usually avoided because of settling that occurs during biodegradation and compaction of the waste.
