The first thing to notice about Clarice Hutchens’ front yard is that it isn’t a nicely manicured green lawn. Her house sits atop a steep hill and as you come up her driveway, you see piles of rocks, shrubs and trees that blend in well with the woods that surround her property.

Hutchens planted this rain garden, a garden built to absorb rainwater, shortly after she and her husband moved into their Ballwin home in 2004.

Walter Wolfner was not prepared for the impact that last year's heavy rains would have on his business, the Riverside Golf Club in Fenton. 

"The velocity of the water was so great that it picked up sand from the Meramec River and deposited it on the golf course," Wolfner said "I mean, we'd never seen things like that before." 

While he managed to clear off all the debris from the golf course, which is adjacent to the river, it took three months to rebuild the clubhouse, which had to be completely gutted and rewired. 

The state of Missouri estimated that more than 7,000 structures were damaged by last winter's heavy rains. Like Wolfner, cities and many residents along the Meramec, Missouri and Mississippi rivers have been trying to recover and rebuild.

Updated Oct. 4 with details on the contamination source — The Missouri Department of Natural Resources has identified a paving company as the source of the white contamination that appeared in Coldwater Creek over the weekend. 

In a statement released Tuesday, the state agency said an accident caused a truck carrying a chemical called Modifier A/NA, an additive used to make concrete, to spill the product into the creek. The St. Peters-based Pavement Solutions was responsible for transporting the chemical.

The concrete additive has low toxicity to humans and aquatic life, according to a Materials Safety Data Sheet for the product.
