A Misstep in the Wrong Direction News on August 25 reported Sheriff Mike Naig unholstering his squirt gun yet again to apply a gentle mist onto the raging inferno that is Iowa’s water quality and overall environmental condition.

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 β€˜zeroed out’

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?

Congrats Polk County! You win the β€œWe 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!

You can’t make this shit up. Representative of IFU says we can β€œsuspect” things like the water, pesticides & fertilizer can cause cancer, but then turns around and says regulations won’t work and farmers simply need to be paid more to change their ways.

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.

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...

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….

Abolish the Department of Agriculture The USDA has become an inefficient monster that often promotes products that are bad for consumers and the environment. Let’s replace it with a Department of Food.
