A landfill in México with visible geomembrane in one of the slopes A landfill cell showing a rubberized liner in place (left). A landfill liner, or composite liner, is intended to be a low permeable barrier, which is laid down under engineered landfill sites.
Since the arc testing method is not dependent on water making good contact through the leak, it is more sensitive and comparatively easy to perform in most types of liner construction (ponds, Landfills, tanks etc.)than the water-based methods. The minimum sensitivity of the arc testing bare geomembrane liner integrity method is a pinhole leak.
In a landfill that receives a mixture of municipal, commercial, and mixed industrial waste but excludes significant amounts of concentrated chemical waste, landfill leachate may be characterized as a water-based solution of four groups of contaminants: dissolved organic matter (alcohols, acids, aldehydes, short chain sugars, etc.), inorganic ...
This is a list of Superfund sites in Kentucky designated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) environmental law. The CERCLA federal law of 1980 authorized the United States Environmental Protection Agency (EPA) to create a list of polluted locations requiring a long-term response to clean up hazardous material contaminations.

Investigators from the Kentucky Attorney General's Office responded to a voting center in Laurel County on Thursday after a video showing a ballot-marking machine selecting the wrong option ...
They separated the machine, conducted proper testing, didn’t find any errors, and confirmed that voters could cast their ballots properly.” Trump then encouraged any citizens to report issues ...
Once a landfill site is full, it is sealed off to prevent precipitation ingress and new leachate formation. However, liners must have a lifespan, be it several hundred years or more. Eventually, any landfill liner could leak, [7] so the ground around landfills must be tested for leachate to prevent pollutants from contaminating groundwater.
The odds of slot-like “gray machines” returning to gas stations, bars and convenience stores across Kentucky just got longer. Franklin Circuit Judge Phillip Shepherd ruled to keep a ban on the ...
