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

2: our lit review found that existing studies often analyze data at non-ideal spatial scales, but they clearly support addressing nat'l DWQ racial/eth & socioeconomic disparities

🔓🚰 we propose combining DWQ + demographic at more "native" scales along w/ infra data, which are often inaccessible

We break it down into 3 parts - each w/ status quo + immediate + future steps

1: we propose a combining extant DWQ datasets + describe challenges. Private well data are needed to make this complete + useful for all.

📊 as shown, any data compilation must acknowl + overcome limits in represent'ness

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 ⏰)

2nd pt is very important for monitoring moving fwd.

3rd: EPA's data indicates that other replacement PFAS (e.g., PFBA) are correlated w/ detections of PFAS that are more commonly regulated in some states. The strongest correlations incl PFAS that EPA is reneging on.

(full paper: bit.ly/43sILON)

2nd: In prior analyses of statewide PFAS monitoring data, we found some clear evidence that *reg status impacts monitoring*. Note below how most water systems w/ incomplete data were missing data on PFAS w/out state regs.

(🔓full paper available open-access here: doi.org/10.1021/acs....)

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).

As I'm finishing up some of these reads now, I'm very excited to start this new book on PFAS by @mariahblake.bsky.social !

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.

A great month for books on environmental health topics!

Plus another book out next month on PFAS!

Hi! Thanks for your reply/signal boost. I haven't submitted a github issue, so that's not mine. My error (see below) seems to relate to a (potentially) corrupt file that can't be opened. Interestingly, it's happening regardless of year & is happening locally (on my PC) + on a RStudio Server.

Another quick #TidyTuesday - a wordcloud of all words used more than once in posit::conf(2024) talk titles

As a newbie (read: complete newbie) to tidytext, it was a small treat learning about the 'stop_words' dataset

Here's another #TidyTuesday I did a few years back (code can also be found via my Github):

This is my first #TidyTuesday in almost two years~

Since it's BYOD (bring your own data) week, I decided to recreate a (very easy) data portrait by W.E.B. Du Bois.

Happy holidays🎄 🕎 🌙
