LEXINGTON, Ky. (WKYT) – Recent heavy rainfall has left soil across the state completely soaked, contributing to localized flooding in some areas.

When rain falls, some water soaks into the ground through a process called percolation.

Soil can only hold a limited amount of water. Once the small air spaces within the soil fill with water, the ground becomes saturated and additional rainfall has nowhere to go.

Soil type plays a role in how quickly water drains.

Much of Kentucky has clay-heavy soil, which is made up of very small, flat particles packed tightly together.

That composition makes it harder for water to move through. In clay soil, water may drain at a rate of only 0.02 to 0.17 inches per hour.

When rainfall comes down faster than the ground can absorb it and water cannot drain into a stream or storm drain quickly enough, it begins to build up.

That buildup is what leads to localized flooding.

BOWLING GREEN, Ky. (WBKO) – Cyclosporiasis is a microscopic parasite that can contaminate food and water — is making people sick across several states, including Kentucky.

Dr. Patricia Tellez-Watson said, the illness is caused by Cyclospora cayetanensis and spreads when someone ingests contaminated food or water. “It is an intestinal infection caused by this water-borne, food-borne microscopic parasite,” she said.

Symptoms can include diarrhea, nausea and vomiting.

Tellez-Watson said, cases are often sporadic, but outbreaks can happen — especially during hot, wet months, when the parasite can survive in the environment long enough to become infectious.

Health experts recommend taking extra precautions with food and water. Washing hands and thoroughly rinsing produce before eating or cooking can reduce risk.

Watson also urged people to be cautious with fresh produce, particularly pre-packaged items, and to consider using bottled water.

Officials have confirmed cases in Bowling Green, though it’s unclear how many.
