Navigating Unexpected Contaminants with Your Geomembrane System

Part 1: What are the Concerns of Unexpected Contaminants

By coincidence, two independent surveys were recently released which identified key issues in the U.S. Water Industry. The reports are:

Wastewater Series:  How Geomembranes help to improve Water quality, lower costs and increase efficiencies in wastewater treatment 

Part 4 - Geomembrane Applications in Secondary - Tertiary Wastewater Treatment and Residuals Management

Wastewater Series:  How Geomembranes help to improve Water quality, lower costs and increase efficiencies in wastewater treatment 

Part 3: Geomembrane Applications in Wastewater Collection and Equalization, and Primary Treatment

Wastewater Series: How Geomembranes help to improve water quality, lower costs and increase efficiencies in wastewater treatment

Part 2:  Wastewater Treatment Processes

The terms attachments, penetrations and terminations are often considered synonymous, or at least in the same family, when used in the context of geomembranes. This post will focus on attachments and specifically a review of ASTM D6497, one of the main guides for geomembrane mechanical attachments.

As Engineers, we use the term “failure” in a number of ways but know that it implies something did not perform as expected. Was it the fault of the “failed” thing or action, or was it a failure in how it was expected to perform, under those conditions? Regardless, we all know that failure brings negative connotations in many ways, and none are desirable.

Resiliency in drinking water systems has become a broad discussion as many systems have experienced operational and quality problems. Like much of our ageing infrastructure, the backlog of needed updates and repairs continues to grow.
