In a guest blog in the Water Efficiency Magazine Dr. Edo McGowan, who has forty years of experience in the development of local, regional, and international programs relating to health aspects of water quality, vector control, as well as, the analyses and disposal of hazardous materials, discusses the legality of water compared to its safety, since there could be many new contaminants existing that may not be found in laboratory tests.

A recent article by Partington et al., identifies a new modeling blueprint, which seeks to link sedimentology, hydrology and hydrogeology for the modeling of streambeds. The link presented below discusses with the authors the challenges and implications of such a modeling blueprint.

The pipelines that municipalities use to deliver drinking water to their residents take a beating. Large cities pump tens of millions of gallons of water to their customers every day. And many of the pipes that municipalities rely on to transport drinking water and treat wastewater are coated with decadesworth of grime and pollutants.
It’s little surprise then, that a growing number of municipalities face a problem: Their aging pipes are so filled with sludge and biofilm that it is reducing the speed at which they can pump water. This means that pumps have to work harder in these systems, increasing the energy costs and the expenses that these cities face when providing drinking water to residents and commercial buildings.

Do you think there is a need for such solutions locally? Would such solutions be applicable in terms of maintenance in the future? Comment below.
Mark your calendar guys for Wednesday April 12th 2017 at 3.00 PM for the above mentioned Webinar on the new 6470 LC/TQ from Agilent Technologies which would be used for the detection of several pharmaceuticals and pesticides in surface waters.
For decades now, the most common detected environmental contaminants in water are pesticides and pharmaceuticals. Because these types of organic compounds are mostly polar, liquid chromatography mass spectrometry has been the methodology of choice for their analysis. Usually a sample preparation step such as solid-phase extraction has been necessary for the detection of these contaminants at low ng/L. However, with the advent of newer and more sensitive instruments, this step can be omitted while still achieving these low detection limits. In this session we’ll show some examples of compounds identified in surface waters at these concentration levels and how to optimize the best conditions and parameters for their optimal detection.
In this session, we’ll focus on the use of the new 6470 LC/TQ instrument from Agilent Technologies for the sub ng/L level detection of several pharmaceuticals and pesticides in surface waters. Examples of optimization of several source parameters and voltages will be shown for the ionization of specific analytes, including hormones. Also, quantitation using larger volume injections (100uL) will be shown for the direct analysis of contaminated water samples.
What you will learn:
- How to optimize intrinsic source parameters in MassHunter software
- Large volume injection (100uL) considerations
- Learn to choose best product ions with Optimizer software
- Method development techniques
- A list of the most commonly detected pharmaceuticals in surface and drinking waters
