The Lloyd Aquifer is the deepest and oldest of Long Island's aquifers. It is a sand and gravel formation ranging in thickness from zero to five hundred feet. At its deepest, it is 1,800 feet below the surface. The water contained in the Lloyd aquifer is about six thousand years old.
But are they actually admissible in court? Courts don't have to admit lie detector tests, according to a U.S. Supreme Court case that specifies how courts deal with scientific evidence. Instead, individual judges have discretion to decide if a polygraph will be admitted based on certain criteria.
In most European jurisdictions, polygraphs are not considered reliable evidence and are not generally used by law enforcement. Courts themselves do not order or facilitate polygraph testing. In most cases, polygraph tests are voluntarily taken by a defendant in order to substantiate his or her defense.
