  • Case study - Pemaco superfund site remediation

    OVERVIEW Pemaco was formerly a chemical facility located in a light industrial and residential area of Maywood, CA, adjacent to the Los Angeles River. No one knows how long hazardous substances had been leaking into the ground but the operations date back to the 1940's.  Up until closure of the facility in 1991, chlorinated solvents, aromatic solvents, and flammable liquids had ...

  • Dewatering with Geotextile Bags - South Gippsland, Australia (Water Treatment) - Case Study

    A simple, cost effective new method of dewatering sludge is now available in Australia, writes Bill Kelly from CRS Industrial Water Treatment. The use of geotextilcs for containment and dewatering came about as a result of a major flood event in Holland in the 1950s. It prompted Dutch marine engineers to seek new methods and materials to build structures for coastal defences. The ...

  • Zerovalent Iron nanoparticles for treatment of ground water contaminated by Hexachlorocyclohexanes

    Ground water and aquifer samples from a site contaminated by hexachlorocyclohexanes (HCHs; C6H6Cl6) were exposed to nanoscale iron particles to evaluate the technology as a potential remediation method. The summed concentration of the HCH isomers in ground water was approximately 5.16 µmol L–1 (1500 µg L–1). Batch experiments with 2.2 to 27.0 g L–1 iron nanoparticles showed that more than 95% of ...

  • Frankfort Electric and Water Plant Board Verifies Distress on Ductile Iron Pipe Using Electromagnetics

    Commercial introduction of ductile iron pipe (DIP) began in the mid-1950s and was established as the most frequently selected material of choice for ferrous pressure pipe by the early 1970s. Due to the widespread use of DIP during a large expansion of pipeline infrastructure in the 1970s, there are many thousands of miles of pressurized DIP in operation today. Water and wastewater utilities ...
