The geologic location of the Seabreeze Environmental Landfill places it atop very low-permeability
clay that restricts the movement of ground water. This natural barrier makes it one of the best
geological locations in Texas to site a landfill. In addition, this modern landfill is constructed with
multiple environmental protection systems to help protect the surrounding environment.
For instance, the liner system is designed to contain liquids and gases naturally generated by decaying
wastes. The liner system consists of a two-foot thick layer of compacted clay with minimum permeability
of 1x10-7 centimeters per second, overlaid with a layer of heavy plastic (high density polyethylene)
that covers the bottom and sides of each landfill area (cell). A geocomposite drainage layer is placed
atop the heavy plastic, and a two-foot thick soil layer covers the geocomposite material to protect it
for punctures. A system of pipes collect and pump liquids out of the landfill for treatment.
In addition to environmental protection systems, we utilize numerous monitoring devices. The
facility currently has 22 ground water monitoring wells and 20 gas probes, which are regularly sampled
and tested by a third-party independent consultant to ensure the site is performing well.
All water sample results are sent to local, state and federal environmental agencies, who monitor and
oversee operations at the facility. This constant monitoring does not stop when the landfill closes. In
fact, Waste Connections will continue to monitor the site for 30 years after we stop accepting waste.
In the meantime, we plan to provide Brazoria County residents and businesses with safe, reliable and
low-cost waste collection and disposal for many years.
