Hoping it's relatively accessible...but thanks for sharing nonetheless!!

Work over several years has found these sites are major predictors of drinking water contamination of #foreverchemicals and they pose threats to environmental justice, including:

The paper should be open-access via PubMed soon but here's a link if you don't access above: wires.onlinelibrary.wiley.com/doi/epdf/10....

We conclude w/ more steps to get started: (1) user-engaged ID of benefits of a database (2) dev of data standards (3) training for citizen scientists on analysis of compiled DWQ data + tools (+ more!)

Grateful for my coauthors for dreaming big but practical & excited to see where it leads! 🔓🚰 🗺️

3: ML is increasingly used to bridge gaps in DWG sampling. It shows promise for advancing DWQ health studies

🗺️ vis tools can combine exposure "surfaces" + measured results. In future, "AI for social impact" tools can assist data compilation if the right collabs are made (env + CS + community)

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

Hi! Just flagging that the Google form allows for 300-character detailed explanations for the visualization, but not 300 words (as it says).

There are a lot of other considerations + implications of these plans that are too lengthy to post here.

I'm not a lawyer so I don't know what all the next policy steps are, but if anyone in the #PFAS / #drinkingwater / #EJ world wants to collab on a public comment to EPA's plans, I'm def on board!

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.
