On a less positive note, there was also a report on Iowa's annual assessment of how many of our surface waters cannot be used for their designated purposes due to water quality issues. In reality, this exercise points out the minimal amount of monitoring the state does, and how few of the resulting plans (TMDLs) are actually implemented.
Nice coverage of Emery Davis and his work with the Indian Creek Soil Health Partnership in the Cedar Rapids Gazette and on local TV stations. In the last month, he has overseen the construction of a biofilter which will remove nitrate from ~100 acres near the Tuma soccer complex, and the installation of a saturated buffer that will do the same for ~40 acres near County Home Rd. and Highway 13 (pictured here). We have done measurements on the tile lines which will be treated by these installations, and will continue to monitor their effectiveness.
