EPA Releases New Policy for Managing Draft Documents

August 20, 2019      Drinking Water Headlines     

EPA’s Office of Water has recently issued a policy for managing draft documents (click here). EPA and the Office of Water use guidance documents to support regulatory programs and provide recommendations for monitoring and sampling protocols. The Agency, to increase transparency, has issued a new policy for managing draft documents that have not been finalized in an appropriate amount of time to reduce confusion. Draft documents that have been issued more than two years ago and not been finalized are now rescinded. Draft documents recently issued, and issued in the future, must be finalized within two years of the draft date, or they will automatically be rescinded.

Existing draft guidance or policy documents that are important to the Office of Water’s national programs will need to be reissued and finalized in reasonable time in accordance with this new policy. The Office of Water intends to establish a website database with the complete collection of guidance and policy documents that are currently effective. New draft and final guidance documents will be uploaded to this database within 30 days of issuance.

JAMA Pediatrics Publishes Study Connecting Fluoride in Drinking Water to Lower IQ in Children

August 20, 2019      Drinking Water Headlines     

Yesterday, the journal JAMA Pedriatrics published “Association Between Maternal Fluoride Exposure During Pregnancy and IQ Scores in Offspring in Canada,” a study that links higher levels of fluoride exposure to lower IQ scores. The study, which has not been released without criticism, measured the maternal urinary fluoride and self-reported maternal daily fluoride intake of around 600 pregnant women in six Canadian cities. About 40% of the sample population lived in cities with fluoridated drinking water and had an average maternal urinary fluoride level of 0.69 mg/L, which was contrasted with the 0.40 mg/L of the sample population that did not live in cities with fluoridated water.

Three to four years after the women gave birth, the researchers assessed the children’s IQ using the Wechsler Primary and Preschool Scale of Intelligence-III. The study concluded that higher levels of fluoride exposure during pregnancy were associated with lower IQ scores in children measured at age three to four years.

Michigan Releases 2018 PFAS Drinking Water Sampling Report

August 16, 2019      Drinking Water Headlines     

The Michigan Department of Environment, Great Lakes, and Energy (EGLE) has released a report entitled, “2018 PFAS Sampling of Drinking Water Supplies in Michigan.” The primary objective for this state-wide PFAS sampling program was to proactively sample CWS, schools, daycares, and tribal locations that utilize groundwater and/or surface water as their sources for drinking water to verify these supplies are protective of the populations they serve. The report includes information about EGLE’s 2018 drinking water sampling approach, results, and findings, along with tables and maps of the PFAS detections throughout the state. As presented in the results section, over 89% of the sampled facilities were reported as non-detect for PFAS. However, due to the use of PFAS in so many commercial products and industries, PFAS were detected in just over 10% of various sampled facilities, and two of the sampled facilities were reported with concentrations above the USEPA Lifetime Health Advisory of 70 ng/L for PFOA and PFOS.

The report also includes information about the 2019 Phase 2 Statewide PFAS Sampling Program that has been initiated approximately 590 additional locations to further evaluate the potential of PFAS impacts in additional locations such as adult foster care providers, children camps, various industries, medical care facilities, offices, motels, and parks. For more information and to read the report, visit the Michigan PFAS Response website.

The National Academies Release Report on Legionella

August 14, 2019      Drinking Water Headlines     

Today, the National Academies of Science, Engineering, and Medicine (NASEM) released a report new report on LegionellaManaging Legionella in Water Systems. The report is a result of the U.S. Centers for Disease Control and Prevention (CDC), the U.S. Image result for national academies of sciences engineering and medicine logoDepartment of Veterans Affairs (DVA), the U.S. Environmental Protection Agency (EPA), and the Alfred P. Sloan Foundation asking NASEM to address the state of the science with regard to Legionella.

The comprehensive report reviews the following:

  • Diagnosis, Ecology, and Exposure Pathways
  • Quantification of Legionnaires’ Disease and Legionella
  • Strategies for Legionella Control and Their Application in Building Water Systems
  • Regulations and Guidelines on Legionella Control in Water Systems

Some of the highlights from the report’s conclusions and recommendations include: 

  • For all types of buildings, hot-water heater temperature should be maintained above 60°C (140°F) and the hot-water temperature to distal points should exceed 55°C (131°F).
  • There is growing evidence that, compared to free chlorine, a monochloramine residual better controls Legionella risk from building water systems, although the reasons for the improved performance are not yet clear.
  • Additional research is needed to evaluate the potential for nutrient limitation (concentration and composition) to control Legionella growth in distribution and building water systems.
  • New NSF/ANSI standards regarding microbial growth potential of materials are needed so that water utilities, plumbers, and building contractors can include Legionella control when making decisions about pipe material usage.
  • There is clear evidence of Legionella amplification in the distal parts of some hot-water systems, likely due to a combination of water stagnation and loss of temperature control and disinfectant residual.
  • Research is needed to better understand the persistence of distribution system disinfectant residuals within building plumbing.
  • Guidance about Legionella is needed for homeowners, especially consumers from at-risk segments of the population.
  • Require Water Management Plans in All Public Buildings Including Hotels, Businesses, Schools, Apartments, and Government Buildings.

Lead in Newark Back in the News

August 13, 2019      Drinking Water Headlines     

Continued lead issues in Newark the past few days prompted another round of media stories that even reached the network news on Monday evening. Over the weekend, testing results showed that two out of the three homes using filters showed continuously high lead levels, and these testing results led to the distribution of bottled water on Monday. The situation is a little unusual, in that the filters are certified and are used on a semi-regular basis across the country, especially when lead service lines are replaced.

The high lead levels are likely from lead services lines in the distribution system. For Newark, the estimate to replace all of the lead service lines is $70 million. The situation in Newark will likely take some time to sort out.

In the meantime, EPA’s Long-Term Revisions to the Lead and Copper Rule (LT-LCR) are still under review by the Office of Management and Budget (OMB). Given the normal 90-day review, the timeframe to complete that review would be September 6th.

Additional Summary Materials from DMUC 19 will be Distributed Next Week

August 9, 2019      SDWIS Prime     

SDWIS Community – due to scheduling conflicts between ASDWA and the EPA SDWIS Team, we will be posting all DMUC-related follow-up materials (Q&As, request documents, polling responses, etc.) early next week. ASDWA and EPA had previously committed to releasing all follow-up items within a two-week timeframe, so we wanted to inform the community of this slight delay. This is to ensure less spam to you, and a more coordinated packaging of all follow-up materials.

As a reminder, all videos and slide decks from the Conference are available on the ASDWA website in the SDWIS User Community [requires login].
