ASDWA – USGS Webinar on Chemical and Microbial Contaminants in Drinking Water

On September 5, 2018, from 1:00 to 2:30 pm (eastern), ASDWA will host a webinar with the U.S. Geological Survey (USGS) entitled, “Understanding Chemical and Microbial Contaminants in Drinking Water:  Raw, Treated, and Tap Water.” The webinar will be presented in three segments to address key issues and questions of drinking water quality. The segments include:

  1. The USGS groundwater quality assessments in 11 principal drinking water aquifers across the US.
  2. The EPA and USGS collaborative effort to provide a more robust dataset on a wide range of chemical and microbial contaminants present in source and treated waters, along with a case example from a participating water utility in Massachusetts.
  3. The USGS partnership effort to quantify tap water exposure pathways in public and private water supplies.

Updated USGS Ground Water Quality Mapper

usgsThe U.S. Geological Survey (USGS) National Water Quality Program has updated its interactive web tool that maps decadal changes in groundwater quality across the nation. The web tool, Decadal Change in Groundwater Quality, now includes more groundwater well networks and data analyzed over a longer time span. In the update, groundwater quality data were added for an additional 218 wells in 6 well networks, increasing the number of wells to 1,718 and the number of well networks to 73.  Additionally, data for 14 well networks resampled during 2012–14 were incorporated, allowing the user to visualize changes across three roughly decadal sampling events for those networks since the 1990s.

Users of the web tool can easily visualize changes in both inorganic and organic constituent concentrations in groundwater, including chloride, nitrate, several pesticides, and some drinking-water disinfection byproducts. The website also includes a description of the methods used to evaluate changes in groundwater quality and a link to the complete set of data. For additional information on the groundwater-quality web tool, or for data and methods used, contact Bruce Lindsey (blindsey@usgs.gov).

July 2nd ASDWA Webinar with USGS on Cyanotoxins in Drinking Water

usgsOn Monday, July 2nd from 1:00 – 2:30 pm (eastern), ASDWA will host its second free webinar in our series with USGS scientists entitled, “Cyanotoxins – Advancing Drinking Water Science to Protect Human Health.” 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 drinking water program personnel are encouraged to attend, along with anyone else who is interested and would like to participate. For more information and to register, GO HERE.

Don’t Forget to Register for Next Week’s ASDWA Webinar on 1,4-Dioxane

1 4 diox chem structureASDWA is pleased to announce a free webinar on Tuesday, June 5th from 1:00 to 2:30 pm (eastern) entitled, “State Efforts to Assess and Address 1,4-Dioxane through Drinking Water, Ground Water, and Clean Water Programs.” 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. The webinar presenters are Brandon Kernen from the State of New Hampshire and Rebecca Sadosky from the State of North Carolina. 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. State, interstate, tribal, and federal water programs, water utilities, and technical assistance providers are encouraged to attend, along with anyone else who would like to participate. REGISTER HERE.

EPA Nonpoint Source Measures Report for Hypoxia Task Force States

HTF MS River statesEPA has published its “Progress Report on Coordination for Nonpoint Source Measures in Hypoxia Task Force States” that provides a summary of nutrient reduction measures among member states. The report was developed by the Hypoxia Task Force Nonpoint Source Workgroup and focuses on the coordinated effort to account for nonpoint source (NPS) changes, primarily agricultural, that influence nutrient loading from a variety of methods. This effort provides additional critical metrics for tracking and informing progress towards reducing nutrients to the Gulf of Mexico that complements other historical aspects of tracking nutrient loading, including Mississippi River and tributary water quality monitoring and tracking point source metrics.

EPA Seeks Comments on Clean Water Act Coverage of Groundwater Discharge Connections to Surface Water

download

On February 20th, EPA published a Federal Register Notice asking for comments on whether point source discharges, that have a direct hydrologic connection to jurisdictional surface waters via groundwater or other subsurface flow, should be subject to Clean Water Act regulation. EPA is requesting comment on whether the Agency should consider clarification or revision of those statements and if so, comment on how clarification or revision should be provided. Comments are due on or before May 21, 2018. Comments must be submitted at http://www.regulations.gov using Docket ID No. EPA-HQ-OW-2018-0063. For more information, view the Federal Register Notice. For questions, contact Scott Wilson of EPA at (202) 564-6087 or wilson.js@epa.gov. For some more perspective, read this Earth & Water Law Group Article.
