“…In addition, sites may have contamination in different media [17]. It is not uncommon, for example, to have also groundwater contamination on sites with extensive soil contamination, so that a range of technologies is needed for remediation of the various contamination problems [5,132].…”

“…Any measurable remediation objective has to consider several factors, which could induce an impact on the decision making process have to be considered, like basic evaluation criteria that include engineering and non-engineering reasons for ensuring the achievability of the "cheaper, smarter and cleaner" soil remediation philosophy, such as [20,28,132,[141][142][143]:…”

“…[41,42] A pyridine vapor pressure of 8.88 × 10 −6 atm is therefore present over a 1 M pyridine solution; hence, the concentration of the pyridine molecules in the solution is 1.1 × 10 5 times higher than that in the pyridine vapor produced from this solution. For example, it follows, therefore, that the vapor from a 1 M solution contains a concentration of pyridine molecules equivalent to that found in a 9 µM solution.…”

We report on investigations upon a surface-enhanced Raman scattering (SERS) substrate produced from a two-dimensional single-walled carbon nanotube (SWNT) network decorated with Ag nanoparticles. Using the strong and unique Raman spectrum of SWNTs as a reference, the SWNT/Ag nanostructure can be considered to provide two regions: one with an ultrasensitive SERS response for single-molecule SERS (SMSERS) study; and another with uniform SERS enhancement over an area of several square millimeters for general SERS measurements. We report the appearance of an anomalous Raman feature at around 2180 cm -1 in the high-sensitivity region which exhibits the characteristics of SMSERS. The SERS performance of the uniform area was characterized using pyridine vapor adsorbed onto the substrate. The presence of the SWNT/Ag nanostructure enhanced the Raman intensity by over seven orders of magnitude, a factor comparable to or exceeding that obtained on SERS substrates reported by other groups. The results indicate great potential to produce highly sensitive, uniform SERS substrates via further fine-tuning of the nanostructure

“…Brown et al (2010) applied surfactantenhanced aquifer remediation (SEAR) as alternatives to conventional pump-and-treat remediation for aquifers contaminated by dense non aqueous phase organic liquids. Suthersan et al (2010) reported a full-scale nonaqueous phase liquid (NAPL) remediation of Area A of the Northeast Site at the Young-Rainey STAR Center, Largo, Florida. Area A covered an area of 930 m 2 (10,000 ft 2 ) and extended to a depth of 10.7 m (35 ft), representing a total cleanup volume of 9930 m 3 (12,960 cubic yards).…”

Most water table aquifers are polluted, yet they are the primary sources of urban and rural water supply. Sustainable hydrology in this millennium will capture in-situ treatment and protection of shallow aquifers particularly in developing countries. Permeable reactive barrier (PRB), biological and electrochemical methods with air and steam injection techniques will advance. Ex-situ pump and treat method is slow, costly and unsustainable. Many private treatment plants for pump-treat-use have been abandoned due to unsatisfactory output and operational problems. In-situ treatment of polluted aquifer starts with mapping pollution source(s), identifying stressors and migration pathway, estimating quantum of stress, and terminating release of stressors from the source. Sustainable hydrology shall also include developing hydrologic models code that can predict pollution, treatment method; amount and period of treatment. This shall be based on the characteristics of the aquifers; the pollution stress and the subsurface.
