What’s in the Water?
The Kansas River, photographed in Lawrence, Kansas.
A glance at the 2010 Water Quality Report reveals a plethora of contaminants in our local water supply. From atrazine - a type of herbicide - to arsenic, the contents of the report are surprising but not unique. We are residents of Lawrence, Kansas, and our water comes from the Kansas River, commonly known as the Kaw. The Kaw is the world’s longest prairie river, according to Friends of the Kaw, a grassroots organization that works to protect and preserve the river. The fact that the Kansas River supplies water for 600,000 Kansas residents emphasizes the idea that everyone is downstream from somewhere. But we are not unique: a quick look at your municipality’s water report will likely reveal much of the same information.
Like most cities, Lawrence’s drinking water and wastewater are treated separately. Topeka puts its treated wastewater (known as effluent) from its wastewater plant into the Kansas River. Lawrence captures water from the river downstream. The local coal-fired plant, also cited near the Kaw, takes water from the River, filters it through three sludging pools, and then dumps the water back into the Kaw. Once treated, people drink the water. And, continuing downstream, once the water is excreted and flushed away, Lawrence, again, treats the wastewater and returns it back to the river. Yet, the water is not a closed system, explains Jeannette Klamm, Utilities Programs Manager for the City of Lawrence. The water is recycled up and down the river: Lawrence’s water treatment plants are upstream from its wastewater treatment plant, and Lawrence’s wastewater treatment plant is upstream from Kansas City’s water treatment plant.
