Integrated models are valuable planning tools that can be used to investigate upgrades and configuration modifications to wastewater treatment systems. A team of Geosyntec wastewater treatment process modeling specialists recently authored a white paper that describes Geosyntec's novel integrated modeling approach for estimating the cost of compliance decisions and optimizing capital/O&M costs based on the permittee's preferred spending plan and risk tolerance. Geosyntec's approach can also estimate risks of non-compliance based on uncertainty in feed…
Performing appropriate environmental assessment, environmental permitting, geotechnical engineering, restoration design, and programmatic environmental compliance work are all important aspects of managing pipeline exposures around waterbody crossings. A challenging component of this work is understanding and managing pipeline exposures for system integrity. Exposed pipelines have an increased potential for abrasion, corrosion, impact, and structural stresses that could compromise the safety and integrity of pipes. Maintenance and restoration work on pipeline exposures must therefore be planned, prioritized,…
SiREM (a division of Geosyntec) has launched an independent website for the Waterloo Membrane Sampler TM (WMS). WMS is a unique passive sampler that can be used for indoor air, ambient air, sub-slab vapor and soil gas sampling of volatile organic compounds (VOCs). WMS was developed at the University of Waterloo by Drs. Tadeusz Górecki and Suresh Seethapathy. The researchers had identified a need for a passive sampler with resistance to water vapor, which can…
Achieving compliance with the U.S. Department of Transportation's recent Pipeline and Hazardous Materials Safety Administration (PHMSA) Interim Final Rule (IFR) on the safety of underground natural gas storage facilities can be a challenging endeavor. The United States has approximately 400 underground gas storage facilities, and 81% of those are depleted hydrocarbon reservoirs which have been adapted and reused for gas storage. Depleted aquifers and salt caverns make up the remaining 19%. Most storage facilities were…
An inadvertent release or inadvertent return (IR) of horizontal directional drilling (HDD) fluid is a condition that develops despite: i) appropriate subsurface investigation, ii) engineering design and analyses of the drill path, iii) evaluation of subsurface pressures, iv) use of appropriate drilling fluids, v) following the drill path that was designed, and vi) monitoring and adjusting drilling fluid pressures throughout the drilling process.An IR can lead to an interruption of the HDD installation with project…
