Previous samples collected at these locations detected microcystins above the 4 parts per billion (ppb) draft health advisory established by U.S. EPA. It is likely that heavy rains received in northern Illinois contributed to the improved conditions in the river. | | | | Date Created: | 07-02-2018 | | | | Agency ID: | | | | | ISL ID: | 000000082324 Original UID: 194987 FIRST WORD: Follow | |
