The Iowa DNR says the 1500 tons of liquid nitrogen fertilizer that spilled into a southwest Iowa river on Monday has now reached Missouri.
In a press release, the agency says cleanup efforts continue along the East Nishnabotna River. Due to low water levels in the river, the concentration of fertilizer is much higher than during normal stream flows, causing concern for all animals due to high nitrate and urea levels.
The DNR also says it is encouraging private well owners in Montgomery, Page, and Fremont counties near proximity to the river to contact their county health department to test their wells for nitrate.
