New ASTM: Standard Practice for Data Recording Procedure for Welding Devices Used to Produce Thermal Fusion Welds in Geomembrane Systems (ASTM D8468-23)
Standard wedge welding devices rely on the operator to properly adjust the welding parameters (temperature, speed, and pressure) which are needed to create a sound weld. Changes in one or more of these parameters during production seaming, whether deliberate or accidental, can lead to poor weld quality. Prior to data acquisition systems, verifying welding parameters throughout the welding process relied solely on periodic visual observations and documentation, leaving substantial room for error. This ASTM standard practice, which requires a data acquisition system to be installed on thermal fusion welding devices, allows for the recording of these welding parameters along the entire length of the welded seam at pre-determined intervals, throughout the entire thermal fusion seaming process. The acquired data can be used in the construction quality control / construction quality assurance program to compare the welding parameters at recorded locations along the welded length to preset values, such as the values obtained during the trial seam, to facilitate detection of anomalies anywhere on the welded length.

Bristol Can Avoid State Lawsuit Over Landfill Through Consent Decree
A design for an ethyl vinyl alcohol (EVOH) cover system over the entire landfill to be submitted by Jan. 30 and install that EVOH system within 60 days of completing all other remedial actions for SWP 588, and no later than a year from now. Joel Kellogg said aside from the sidewall emission mitigation system and a geomembrane cover, “everything in there is things that city of Bristol Virginia should have been doing all along to properly maintain a landfill according to regulations.”
