An advanced containment system for containing buried waste and associated
leachate. The advanced containment system comprises a plurality of casing
sections with each casing section interlocked to an adjacent casing
section. Each casing section includes a complementary interlocking
structure that interlocks with the complementary interlocking structure on
an adjacent casing section. A barrier filler substantially fills the
casing sections and may substantially fill the spaces of the complementary
interlocking structure to form a substantially impermeable barrier. Some
of the casing sections may include sensors so that the casing sections and
the zone of interest may be remotely monitored after the casing sections
are emplaced in the ground.
