The Carel Corporation was
chosen, after an interview process, from a field of four other
national and local consulting firms to design and permit a
groundwater monitoring system for a municipal solid waste landfill
located in West Texas. The Carel Corporation’s design was one of the
first in the State of Texas to be approved under the State’s new
Solid Waste Regulations. The innovative design required far fewer
monitor wells than originally anticipated by the client.
The process involved a permit modification with public notice. After
the modification was approved by the TCEQ, The Carel Corporation was
retained to direct the installation of the new monitor wells
required. The drilling technique used involved air rotary with
advancement of outer protective casing during drilling operations
due to the depth (400’) and geologic strata. The drilling technique
allowed us to perform detailed logging of the geologic strata and
provided for thorough observation of water content during drilling.
The detailed logging in turn allowed us to construct the wells so
that the screen, filter pack, and annular seal were at optimal
locations within the saturated zone. The end result was an
efficiently designed monitoring network and skillfully constructed
monitoring wells that provide low turbidity groundwater samples.
