State drinking water programs and anyone else interested in these topics are encouraged to attend. During the webinar, the USGS will present:
Recent and past results and current plans of collaborations with human-health experts from its continuing efforts to research and model arsenic exposures in private and public drinking water sources across the United States.
Provide data for hundreds of chemical and microbial analytes collected from the taps of residences representing a subset of cohorts from their study with partners. The partners include EPA, City of East Chicago, Utilities Department; Indiana Department of Environmental Management, Drinking Water Branch; National Institutes of Health/National Institute of Environmental Health Sciences (NIH/NIEHS); and University of Illinois at Chicago, School of Public Health.
Share information about the tap water exposure analytical toolbox (target chemical, non-target chemical, biological, effects bioassays) to assess contaminant exposure from shallow private wells at approximately 30 Agricultural Health Study (AHS; a long-term public health cohort study in collaboration with the University of Iowa) participants’ farms in Iowa. Site selection will be based on aquifer vulnerability (e.g. alluvial aquifers and bedrock aquifers with thin overburden) to surface applied agricultural contaminants (i.e. pesticides).

Changing Source Water Quality – Links to Potential Corrosivity and Emerging Assessment Tools
Original Broadcast: November 19, 2018
Slide Decks:
ASDWA-USGS Corrosivity Webinar Introduction
ASDWA-USGS Corrosivity Webinar - Steve Preston
ASDWA-USGS Corrosivity Webinar - Ted Stets
Corrosion in water distribution systems is a costly problem and controlling corrosion is a primary focus of efforts to reduce lead (Pb) and copper (Cu) in tap water. Efforts to control corrosion rely upon an understanding of the chemical characteristics of surface water and groundwater sources, yet source waters in some areas are changing rapidly due to anthropogenic inputs and management practices. Recent findings of the potential corrosivity of the Nation’s surface waters and groundwater will be summarized along with implications for exceedances of lead action levels in drinking water. Changes in source-water chemistry at the national scale will also be presented along with insights into the land-use linkages to those changes.
USGS has developed, or is developing, a variety of drinking-water related models and online web applications. The Nation’s rivers, streams, and groundwater are valuable resources, providing sources of raw drinking water for a growing population. New USGS online interactive mappers bring together decades of water-quality data to provide a nationwide look at changes in surface-water and groundwater quality and provide decision tools for monitoring and for developing source-water management strategies.

ASDWA-USGS Corrosivity Webinar - Ted Stets
Corrosion in water distribution systems is a costly problem and controlling corrosion is a primary focus of efforts to reduce lead (Pb) and copper (Cu) in tap water. Efforts to control corrosion rely upon an understanding of the chemical characteristics of surface water and groundwater sources, yet source waters in some areas are changing rapidly due to anthropogenic inputs and management practices. Recent findings of the potential corrosivity of the Nation’s surface waters and groundwater will be summarized along with implications for exceedances of lead action levels in drinking water. Changes in source-water chemistry at the national scale will also be presented along with insights into the land-use linkages to those changes.
USGS has developed, or is developing, a variety of drinking-water related models and online web applications. The Nation’s rivers, streams, and groundwater are valuable resources, providing sources of raw drinking water for a growing population. New USGS online interactive mappers bring together decades of water-quality data to provide a nationwide look at changes in surface-water and groundwater quality and provide decision tools for monitoring and for developing source-water management strategies.

PFAS Treatment Options and Considerations for Drinking Water Utilities
Original Broadcast: October 17, 2018
Slide Decks:
PFAS Treatment Webinar 10-17-18 - Introduction
PFAS Webinar Oct 17 - TIGG
PFAS Webinar Oct 17 - Calgon
Description: This free webinar will share information from four companies that offer PFAS treatment technologies for drinking water utilities. State drinking water programs will learn more about the different PFAS removal/treatment technology options and considerations for water systems in their state. State, interstate, tribal, and federal water program personnel are encouraged to attend, along with anyone else who would like to participate.
Webinar Agenda:
Purolite: Jord Yniguez, the Applications Engineer, will share information about Ion exchange resins such as the highly selective Purolite® PFA694E can remove both short and long chain PFAS compounds to non-detect levels. Purolite has data on several full scale and pilot scale systems which shows benefits over granulated activated carbon (GAC). Ion exchange resins have better PFAS removal abilities and cost saving potential in terms of both capital and operating costs over GAC. Ion exchange resins require shorter empty bed contact times (EBCT) and have high overall capacity for PFAS compounds which lead to smaller sized vessels and less frequent media change outs.
Calgon Carbon Corporation: Eric Forrester, the Applications Engineer, and Alexandra Lynn, the Product Manager and Senior Process Engineer, will provide a review of Calgon Carbon's extensive history and experience removing PFAS from water using Granular Activated Carbon (GAC) and Ion Exchange (IX) technologies. The technologies are evaluated for PFAS removal via lab, pilot, and full-scale performance data from waters around the country. The impact of media service life on long term project costs is reviewed, and the disposition of spent media (incineration, landfill, recycling, etc.) is considered.
TIGG LLC: Karl Kuchling, Business Development Manager, will present the considerations that must be reviewed during the selection process of the media. Topics that will be covered include flow rates, water quality, surface vs ground water, pilot studies, mass transfer zone and when the media should be changed. Since TIGG uses the media that the other participants will be discussing, this presentation will be based upon the factors that go into providing a solution for each individual application.
Evoqua Water Technologies, LLC: Caitlin Berretta, the Business Development Manager and John Lombardo, the Product Manager, for Environmental Solutions, will provide an overview of Evoqua’s approach to PFAS removal from water. This presentation will review the suite of PFAS technology capabilities including Granular Activated Carbon (GAC) and Ion Exchange resin as well as the pros and cons of each. Successful case studies from communities across the country will also be shared.

ASDWA-USGS Chem & Microbial Webinar - ASDWA Introduction
ASDWA-USGS Chem & Microbial Webinar - Groundwater Sources
ASDWA-USGS Chem & Microbial Webinar - Water Quality from Source Through Treatment
ASDWA-USGS Chem & Microbial Webinar - Water Quality from Distribution to the Consumer
This webinar will cover the spectrum of chemical and microbial contaminants in raw (source) water, to treated water, to water at the tap. The webinar will be presented in three segments to address key issues and questions of drinking water quality. The segments include:
Groundwater Sources—The U.S. Geological Survey (USGS) is assessing groundwater quality in principal aquifers that are important sources of drinking water and comparing constituent concentrations in raw (untreated) groundwater to human-health benchmarks established for drinking-water quality. Findings on the occurrence of organic and inorganic constituents, including radioisotopes, from 11 principal aquifers across the United States will be summarized. (presented by Bruce Lindsey, ~15 minutes)
Water Quality from Source Through Treatment—The U.S Environmental Protection Agency (USEPA) Office of Research and Development and the USGS joined efforts to broaden the scope of existing public drinking water information by providing a nationally consistent and rigorously quality-assured dataset on a wide range of chemical and microbial contaminants present in source and treated waters. The two agencies analyzed water samples for 233 chemical and 14 microbial contaminants in source (untreated, raw) and treated drinking waters from 29 drinking water treatment plants. The results of this collaborative effort, published in 2017 as a series of eight papers, will be summarized, as will a follow-on research publication that applied knowledge gained from this study to better understand the potential for de facto water reuse by drinking water utilities. The importance of collaboration between Federal agencies and drinking-water utilities to the success of these studies will be examined through the experience of a participating utility. (Presented by Ed Furlong, Susan Glassmeyer, and John Sullivan, ~30 minutes)
Water Quality from Distribution to the Consumer—The USGS and collaborators recently began efforts to quantify tap water exposure pathways in public and private water supplies. Future plans and preliminary results of pilot efforts from several homes and offices to collect representative tap water samples for analyses of chemical and microbial contaminant mixtures, bioassays, and site-specific exposure activities based on USEPA ToxCast effects data will be presented.

Slide Decks:
Cyanotoxin Webinar - Jennifer and Keith Slide Deck - 7-2018
Cyanotoxin Webinar - Ruth Briland Slide Deck - 7-2018
This is the second webinar in a series of planned ASDWA talks by USGS scientists.
Optimized drinking water treatment is necessary to mitigate a range of chemical and biological risks, including cyanotoxins produced by cyanobacteria. Visible cyanobacteria or detectable cyanotoxins in surface waters may trigger drinking water treatment modification or the use of alternative water supplies, which often require substantial economic investments with little-advanced notification. Multiple approaches are required to better understand actual risks to human health and facilitate the development of tools that guide drinking water treatment and human health decisions. Currently, non-enforceable USEPA Health Advisories are available for some cyanotoxins in finished drinking. Decision makers need to balance the management of contaminants that are regulated and unregulated in drinking water, as well as the costs of achieving treatment targets. This webinar will focus on cyanotoxin occurrence and potential exposures in the Nation’s surface water resources. Tools that are being developed and used to quantify changing water quality conditions that may affect drinking water treatment processes and potential for cyanotoxin exposure also will be described. Information will be presented from the perspective of USGS scientists and the Ohio EPA to demonstrate how converging lines of evidence can be used to better understand and be prepared for cyanobacteria-related events.

State Efforts to Assess and Address 1,4-Dioxane through Drinking Water, Ground Water, and Clean Water Programs
Original Broadcast: June 5, 2018
Slide Decks:
ASDWA Webinar - Introduction
New Hampshire - 1-4 Dioxane - Brandon Kernen
North Carolina - Dioxane June_2018 - Rebecca Sadosky
The purpose of the webinar is to share information about state efforts to assess and address 1,4-dioxane, an unregulated contaminant that is causing states and water utilities to become increasingly concerned about potential health impacts from elevated levels of 1,4-dioxane in both groundwater and surface water drinking water sources. This webinar also builds on the efforts of ASDWA, the Association of Clean Water Administrators (ACWA), the Ground Water Protection Council (GWPC), and EPA to share and promote Clean Water Act and Safe Drinking Water Act (CWA-SDWA) coordination activities across state and EPA water programs.
Intended Audience: State, interstate, tribal, and federal water programs, water utilities, technical assistance providers, and anyone else who would like to participate.
Agenda
New Hampshire: Brandon Kernen will present how the solvent stabilizer 1,4-dioxane has emerged as an unexpected groundwater contaminant at many sites and in drinking water supplies in New Hampshire and nationally. Although this contaminant has been used as a stabilizer for certain types of chlorinated solvents, most historic groundwater monitoring and remediation did not adequately address this contaminant. Additionally, 1,4-dioxane is an impurity in numerous personal care products and has been detected in treated municipal wastewater effluent. Over the last ten years, toxicity assessments coupled with new analytical techniques which achieve lower reporting limits for this compound have revealed that this highly mobile, recalcitrant and probable carcinogenic contaminant warrants the attention of drinking water professionals. This presentation will cover:
Uses, sources, occurrence and fate and transport of 1,4-dioxane
Toxicity information and federal and state regulations and guidance
Laboratory analytical techniques
Examples of contaminated sites and sources of drinking water
Treatment options and costs
North Carolina: Rebecca Sadosky will present information about efforts by the North Carolina Division of Water Resources to assess and address 1,4-Dioxane in multiple river basins throughout the state. These efforts included a two-year study that was collaboratively designed by Safe Drinking Water Act and Clean Water Act staff to examine ambient concentrations, identify potential sources, and document water quality improvements due to abatement efforts of 1,4-dioxane in major surface waters of the Cape Fear River basin. Three of the four study areas were located immediately downstream of domestic wastewater treatment facilities, indicating that these facilities were likely conduits for 1,4-dioxane from industrial sources into surface water. The study findings were communicated to effected municipalities, project partners, and the interested public. During the second year of the study, quarterly sampling indicated a reduction of 1,4-dioxane concentrations in many areas of the basin. Further reductions will be necessary to achieve federal and state health advisory levels for 1,4-dioxane in drinking water supplies. The Division of Water Resources study is continuing in the Cape Fear River basin and has now expanded into the Yadkin and Neuse River basins.

Source Water Collaborative Webinar: A Preliminary Look at the National Forests to Faucets Analysis 2.0
Original Broadcast: May 9, 2018
Slide Deck: F2F2 Souce Water May 9
The Source Water Collaborative presents “A Preliminary Look at the National Forests to Faucets Analysis 2.0 (F2F2).” During the webinar, Sally Claggett of the US Forest Service will share how they are updating the original Forests to Faucets analysis to quantify, rank, and illustrate the direct geographic connection between private and public forests, surface water drinking water supplies, and populations that depend on them. The new F2F2 includes a three-part analysis of the:
Inherent ability of watersheds to produce clean water, based largely on land use.
Most important watersheds to surface water drinking water supply users.
Various threats to forests and the quantity of surface water drinking water supplies.
Altogether, the F2F2 project will provide a broad view of the land use characteristics and water supply threats to watersheds that feed surface water drinking water sources. It does not displace the need for local land use data, local knowledge, or different analyses of hydrologic regimes. F2F2 will, however, be useful for long-range planning, municipal education, and prioritization of regional water needs, including indicating where alternative water supplies may be needed. It will also help those making land management decisions know where practices may be needed to conserve or restore forests.

Opening Pandora’s Box – Evaluating the Integrity of Water System Monitoring
Slide Deck: Evaluating the Integrity of Water System Monitoring
In 2014 – 2015 the Washington State Department of Health conducted the Disinfection Data Integrity Project. The yearlong study investigated disinfection measurement, recording and reporting practices in 33 surface water treatment plants located in the Northwest Region of Washington State. Deficiencies were identified in all 33 treatment facilities that affect the accuracy of the calculated pathogen inactivation achieved by the disinfection processes. Pathogen inactivation level errors of over 100% were identified when more accurate data was used.
Accurately determining chlorine disinfection inactivation levels is complex. Three water quality (WQ) parameters: chlorine residual, pH, and temperature are used along with the time the disinfectant is in contact with water before the first customer (contact time) to determine disinfection efficiency. Contact time is dependent upon three more parameters: the volume of the contact vessel, the baffling efficiency of the contact vessel, and the water flow rate. Each one of these components (three WQ parameters, contact vessel size, efficiency, and flow rate) can and do affect data integrity and impact the accuracy of calculated disinfection inactivation levels used to ensure public health protection.
An average of eight issues that affect data accuracy were found at each utility suggesting that water monitoring data integrity is not robust. This presentation will share study findings and explore ways to improve practices at your utility.

Unlocking the Black Box – Exploring Turbidity Data Integrity at Water Treatment Plants
This webinar was broadcast on Jan 08, 2018
Slide Deck: Turbidity Data Integrity 1-8-18
Turbidity measurements are the single most important parameter used to determine that surface water treatment plants are working correctly and that the filters are removing potential pathogenic organisms from the source water. The accuracy of the turbidimeter data generated, recorded and reported to utilities and oversight agencies is affected by a surprising number of factors that include instrument settings, sampling locations, electronic data manipulation, operational practices and human actions. The Washington State Department of Health (DOH) conducted a study of turbidity monitoring, recording and reporting practices in 25 rapid sand filter plants located in the Northwest Region of Washington State and found deficiencies in all 25 plants that could or did affect the accuracy of the turbidity data reported to the DOH. For instance, 100% of the surveyed plants had turbidimeters set to incorrectly hold and send the last shown turbidity value to SCADA when communication with the sensor is lost. With this setting treatment plant staff and alarm systems do not know that the sensor is no longer operational.
