Chemical Movement

Persons working in water utilities have always warned about the harm that fertilizers and insecticides can pose to water sources, especially when it comes to contaminating surface and ground water sources that contribute to the potable water supply.

In a recent article by Janice Kaspersen, published in the Erosion Control magazine 8 October, 2018, she highlights new research that precisely predicts the movement of such chemicals in soils, in an affordable and effective way that may one they be used on a large scale.

On Integrating Sedimentology and Hydrogeology in Streambeds

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.

NGWA Virtual Conference – “After the Drought”

This virtual conference titled “After the Drought”, carded for the September 6th, 2017, will  provide insight into mitigating efforts used across the United States in recent drought situation. Thus, participants will learn about measures that were used to manage both surface water and groundwater resources during the drought periods.

Clicking on the link will provide relevant pricing for members (who are offered discounted prices) and non-members.

Persons conducting research in this area are also invited to submit abstracts for video clips that would be used in the conference. You can find such guidelines here.

I do hope that some members of staff will be to register for this conference and take advantage of the information provided.

Webinar – Analysis of Environmental Contaminants in Water Using an Agilent 6470 LC/TQ Instrument

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

Upcoming Webinars from AWWA (Some are free!)

Hey guys just received an up-to-date listing of webinars from AWWA including free webinars. Exciting stuff indeed. Don’t forget to check it out…

March 23, 2016 | 11:00 a.m. – 12:30 p.m. MT

This webinar will cover the fundamental water quality monitoring applicable to conventional surface water treatment, the interactions among the monitored parameters, and how that information is used to execute chemical feed and treatment process changes.


  • Chris Fox, Director of Water Quality, MUD of Omaha
  • Brian Thorburn, Senior Operator, EPCOR Water Services
  • Scott Borman, General Manager, Benton Washington Regional Public Water Authority





This complimentary webinar is sponsored by Neptune

Facing limited resources and a rapidly changing workforce, how can today’s water utilities implement technology without sacrificing investments they’ve already made? In this webinar, Neptune Technology Group will demonstrate how today’s water utilities can easily move forward – not only from automatic meter reading (AMR) to fixed network advanced metering infrastructure (AMI) – but beyond basic billing functions to leverage metering data for unique needs across the utility. With backward-compatible, smart water technology, utilities can future-proof and optimize their AMR-to-AMI system, without stranding assets, or hidden licensing and upgrade fees.

Participants will hear from an actual water utility on how it implemented a cost-effective, timely AMR-to-AMI system for its unique needs – simply and painlessly – without stranding assets, and at the utility’s own pace.


  • Chuck Brunson, Principal Product Marketing Manager, Neptune Technology Group
  • Deb Geier, Utility Resources Manager, Wausau Water Works

April 21, 2016 | 11:00 a.m. – 12:30 p.m. MT

This complimentary webinar is sponsored by Bentley Systems, Inc.

Unidirectional flushing (UDF) of water distribution systems is the focus of this webinar. The presentation begins with a thorough background on UDF and explains in which cases UDF is a useful pipe-cleaning method. The speakers will then describe how hydraulic modeling can help with planning and implementing successful UDF programs. The webinar will close with a demonstration of a typical flushing study workflow within a WaterCAD/WaterGEMS hydraulic model as the latest flushing capabilities an available software provides are reviewed.

System flushing is an important method of controlling water quality throughout a water distribution system network. Flushing stirs up and removes sediments from mains and clears poor-quality water from the system, replacing it with fresh water from the source. The webinar speakers will review key rules of flushing and what to do when rules conflict. Guidelines for UDF programs will also be reviewed to give attendees best practices to implement for an effective UDF program.
