Thanks, Eli! Much appreciated.

Why aren’t more people talking about this? Seems notable that Polk County officials don’t care to promote or raise awareness about the report’s conclusions. Are any local reporters gonna ask Polk County folks what’s going on here?

A report tied Iowa’s water pollution to agriculture. Then the money to promote it mysteriously disappeared
Roughly $400,000 in the $1m budget was for public awareness – but those funds were recently ‘zeroed out’

Congrats Polk County! You win the “We All Want Clean Water” award for 2025 for zeroing out the CISWRA budget after funding a report and holding a community event that energized Iowans to take action on our water quality. Way to sustain the momentum!

Sounds more like ransom or extortion to me….

Chris is spot on in this piece. Who wins with this decision? New dischargers. An enterprising reporter should track who receives new discharge (NPDES) permits into these segments now. Those are the interests that greased the skids to make this happen, Iowans’ water quality and health be damned.

The article is paywalled, but this is some complete and utter bullshit…

Were I to run for governor, I would make environmental quality a centerpiece of my campaign from the word "go," rather than trying to workshop something on the fly. And to be honest, I'd probably just plagiarize @theswinerepublic.bsky.social. open.substack.com/pub/riverrac...

I’m old enough to remember when American Public Media reported that saturated buffers are a sham and a waste of taxpayer dollars. Here, we celebrate this wasteful spending as if that report never happened….

A hog slaughtering facility in Sioux City, Iowa promised to bring jobs to town, but blood and pollution came with Seaboard Triumph Foods as well. In footage provided to Sentient, animal waste can be seen flowing into a drain in the ground.

And if Iowans are looking for a local angle, we have been waiting since 2010 for a new health assessment of nitrate that may tell us the SDWA standard of 10 mg/L as N isn’t sufficient to protect folks from cancer and adverse birth outcomes. The future of that assessment is seriously in doubt….
