Contaminants of Concern Webinar Series


Webinar Descriptions

An Experiment in Environmental Leadership: Denver Water Variance Experience
Tuesday, May 12 | 1:00 - 2:30 p.m. Mountain Time | Recording included in series registration!

Webinar Presentations:

Denver Water’s Pursuit of a Variance to the LCR Rather Than Accept Orthophosphate as OCCT
Nicole Poncelet-Johnson, Denver Water, Tyson Ingels, Colorado Department of Public Health & Environment

What we have Learned with Four Years of Pilot Studies on Harvested Lead Service Lines and Coupon Studies under Identical Conditions
Chris Corwin, Corona Environmental Consulting

A population Weighted Lead Exposure Model to Determine Equivalence between OCCT and the Requested Variance
Chad Seidel, Corona Environmental Consulting

Manganese: Exploring Treatment Technologies
Thursday, May 14 | 1:00 - 2:30 p.m. Mountain Time | Recording included in series registration!

Manganese (Mn) is a frequent challenge for both surface and groundwater drinking water systems.  Successful management of Mn often involves both treatment at the source and stabilization of accumulated (legacy) Mn in the distribution system. Although Mn is considered an aesthetic concern, there is increasing evidence that the presence of Mn in drinking water may be related to undesirable health effects in humans. For these reasons, water professionals need to be well versed in the treatment of raw water Mn and management of legacy Mn. This webinar will present the most current guidance regarding the both the treatment of Mn and management of legacy Mn. It will also cover an investigating of improvements to manganese treatment by biological processes and review a successful implementation of manganese treatment that also managed iron and disinfection byproduct levels.

Webinar presentations:

A Review of Manganese in Drinking Water: Chemistry, Treatment, and Impact on Distribution Systems
Phil Brandhuber 

Renton's Maplewood Well Field Water Quality Improvements
Milton Larson, Kennedy/Jenks Consultants

Creative Process Combinations for Simultaneous Control of Mn, Fe and DBPs
John Tobiason, University of Massachusetts Amherst

Regulatory Concerns and Updates for Inorganic Contaminants
Tuesday, May 19 | 1:00 - 2:30 p.m. Mountain Time

In this webinar, recent and expected regulatory changes concerning inorganics will be covered. Results from a National Utility Survey on utility perspectives and experiences managing corrosion control in the distribution system will be presented.  Additionally, an overview of findings related specifically to inorganic contaminants from UCMR4 will be presented in this installment of the webinar series.

Webinar presentations:

Regulatory Update on Inorganics
Steve Via, American Water Works Association

Evolving Utility Perspectives and Experiences with Corrosion Control – Results from a National Utility Survey
Roger Arnold, Hazen and Sawyer

An overview of Inorganics findings in UCMR4
Andrew Eaton, Eurofins Eaton Analytical

Corrosion Control
Friday, May 22 | 1:00 - 2:30 p.m. Mountain Time

This webinar focuses on evaluating corrosion control in the distribution system and providing recommendations based on pilot-scale studies. Health Canada’s considerations for updating the Corrosion Control Guidance document will also be covered.

Webinar presentations:

Considerations in Updating the Corrosion Control Guidance  Document
France Lemieux, Health Canada Water and Air Quality Bureau

Evaluation of Phosphate- and Silicate-Based Corrosion Inhibitors using a Pilot-Scale Distribution System
