Check out our recent open-access paper on adoption of advanced treatment tech effective for emerging contaminants (like #PFAS) in US community #drinkingwater systems!

US drinking water quality disparities are well-documented, but few studies have considered how treatment infra differs across community water systems. Our new OA paper in @envsci.rsc.org uses treatment records to examine the rates that these systems adopted advanced treat techs from 2004-2022.

Many Trump agencies are functionally the opposite of their intended purpose but it's pretty hard to beat an EPA that stops considering human health in favor of just considering regulations' costs to businesses and rolls back the CO2 endangerment finding. Like that's EPA inside the mirror realm.

I think this is actually what they were referring to when they coined MAHA.

Excited for the @agu.org conference next week in New Orleans! ⚜️ @agugeohealth.bsky.social I'm co-convening a session + talking (⬇️). Session will touch on drinking water quality, one health, climate change, hydrology, machine learning, and public health 🌊🚰 🗺️ Hope to see you at #AGU2025

It seems like the Environmental Health Perspectives ( #EHP ) website is now fully down? 😓 The irony is thick: the admin has stated interests in open science and chemical regulation, but has taken down an open-access #environmentalhealth journal with good peer review practices.

Haven't posted on here much over the past few months, but I can confidently say my most used words are still pretty on point. My most used emojis:🚰 🗺️ 🔓 (Check out anisota.net/harvest to do the same.)

While the administration has said it is cutting “woke programs” that “poison the minds of Americans", it actually funded fewer grants in every area of science and medicine. “They brought everything to a stop,” said Sarah Kobrin, a branch chief at the N.I.H.’s National Cancer Institute

Giving a virtual talk next Tues w/ the Swetland Ctr for Environmental Health! I'll focus on: 1) US water systems + the communities they serve, 2) barriers to advancements in water treatment processes, and 3) data availability to advance the field and its impact.🚰 🏙️ Register: shorturl.at/93E6a

The Trump administration just skirted normal channels for hiring directors of the National Institute of Environmental Health Sciences—during a hiring freeze—to appoint a scientist who calls JD Vance one of his “closest friends.”

Months before catastrophic floods swept through an Alaska Native village on Sunday, the Trump administration canceled a $20 million grant meant to protect the community from extreme flooding. At the time, the EPA administrator said he was eliminating "wasteful DEI and Environmental Justice grants."

Did we MAHA yet?

Sharing our new perspective piece in WIREs Water. We propose a publicly accessible + unified drinking #water quality (DWQ) database to address exposure disparities even as fed support vanishes: doi.org/10.1002/wat2... Goal: unify DWQ + infrastructure + demographic data w/ new data vis tools🚰 📊 🗺️

Co-convening a session at the @agu.org meeting this Dec: "Harnessing Geospatial Data to Address Drinking Water Exposures and Public Health Impacts" 🚰🗺️ Welcoming topics @ intersections of hydrology, contaminant modeling, exposure, env justice, & health: bit.ly/4nFJ40M (July 30 ⏰)

We need a story that reminds us our lives are stitched to the soil, the air, and the water—that every breath, every bite, every sip binds us to the earth and to one another.

The sense of relief, vindication, & hope in the courtroom was undeniable—the emotion was so thick you could feel it in the air as justice & the value of our research were finally affirmed

Was so happy to speak with the @ilinseagrant.bsky.social and the Sea Grant community last month! 🚰 Disparities in Contamination by PFAS in US Community Water Systems Top line: EJ research & action will continue even as federal momentum shifts to oppose it! youtu.be/m6GJWwxNNvE?...

EPA stated plans to backslide on its finalized #PFAS drinking water regs. I'm highlighting some problems with this (w/ graphs!) from my own research 🚰 1st: some replacement PFAS (incl. some they are reneging on) are more freq detected than the "legacy" PFOA & PFOS. This is based on EPA's own data!

As the EPA attempts to backslide on important regulations for several replacement PFAS, let's not forget what the data coming out of the EPA currently show: Several replacement PFAS are more frequently detected in drinking water than their legacy counterparts (PFOS and PFOA).

This is a really beautiful tool for conveying impact. Print them out as posters and flyer your town with them! silencedsciencestories.com/the-scientists

Fun (and sampling) at Cambridge Water Department today 🚰💧 Beyond the facility and staff, I'm also really amazed by all the art in the building - check out the floors in the lobby, which depict all of the water mains of the city.

For #TidyTuesday this week, we're looking at data on terminations of NSF grants 📊 🎨 Using colour to highlight one category 📈 Transparency to highlight the important data ✍️ Annotations instead of a legend for transparency #RStats #ggplot2 #DataViz

Powerful graphic. In a single day on April 25, a DOGE-fueled NSF canceled 340,226 future days of research. Or 932 years. [And that’s just one of three rounds of terminations so far.]

A great month for books on environmental health topics! Plus another book out next month on PFAS!

May be speaking to the void here, but anyone in the #RStats world having trouble with #tidycensus API calls? I'm currently getting errors, but (seemingly) only when trying to also get feature geometries. I know there were some outages earlier this year...hoping it's not that again 😨

Escaping some doom + gloom by devoting more time each month to reading papers front to back (something I did periodically during my PhD, but hoping to do more now!). The goal is a mix of reading for fun + more immediate practicality w/ note-taking. This week's docket (1/5)

This is awful and will undermine #EPA's ability to protect public health and the environment. Just in the field of #PFAS, much of what we know about the range of PFAS compounds in our environment and the extent of PFAS contamination was uncovered by the extraordinary work of EPA scientists.

Devastating. One snippet of what #EPA ORD has accomplished in just the last year: create the most comprehensive map of US water system service area boundaries to date. www.nytimes.com/2025/03/17/c...

I'm happy to announce version 4.0 of the PFAS statewide sampling dataset is available online! Key updates: add'l state data and more detailed documentation of analytes Sample data + metadata are available below - feel free to contact me for full version! dataverse.harvard.edu/dataset.xhtm...

Environmental Justice pages down. No surprise--just witnessing

Public water systems with more Hispanic and Black customers were more likely to have these unregulated industrial contaminants and to be close to pollution sources. This study reminds us to take a broad look at our drinking water—beyond regulated contaminants.

Our new Silent Spring Institute paper in Environmental Health Perspectives found that nearly a third of people in the U.S. have been exposed to unregulated contaminants in their drinking water that could impact their health. ehp.niehs.nih.gov/doi/10.1289/... with @jahredwithanh.bsky.social

💧 Unregulated Contaminants in Water Over 97 million US residents are now exposed to unregulated contaminants like PFAS in public water systems, disproportionately affecting Hispanic & Black communities. A stark example of systemic environmental inequities. 🔗 doi.org/10.1289/EHP1... #SciComm 🧪
