  • Using AquaBupH to adjust aquifer PH: ESTCP-funded project at Charleston Naval weapons station - Case Study

    Elevated levels of trichloroethene (TCE) were found in groundwater at a Department of De-fense (DoD) facility in Charleston, SC. Under an ESTCP-funded in situ technology demonstra-tion project , the Navy had been effectively remediating contamination until a drop in aquifer pH caused dechlorination rates to decline. Solutions-IES responded with a study and applica-tion of buffered substrate to ...

  • A Review of Cavitation-Erosion Resistant Weld Surfacing Alloys for Hydroturbines

    AbstractAn improved weld surfacing alloy has been developed and tested to resist cavitation-erosion in hydroturbines. Typical wear characteristics experienced in laboratory testing has been correlated to actual service conditions. A metallurgical evaluation shows that a high strain, work hardening austenitic stainless steel produces superior resistance to cavitational erosion. Several industrial ...
