Recent flooding has caused the utility that provides drinking water to Kansas City, Mo., to fail to meet standards for the treatment of the parasite cryptosporidium, the utility said in a release Friday.

KC Water said the concern over the parasite, which can cause gastrointestinal problems, is not enough to issue a boil order. But the utility’s release warned that the elderly, people with infants and people with extreme health conditions should be aware.

The Missouri Department of Natural Resources was notified, and KC Water said the state agency does not consider the water quality an emergency.

Floodwaters reached record and near-record levels in parts of Nebraska, Iowa and Missouri north of Kansas City. Though flood levels aren’t as bad in the Kansas City area, the water is still high enough to impact water treatment plants.
