On Thursday, parts of downtown, west and southwest Columbus, Ohio, all of which use the Dublin Road Water plant, were issued a nitrate warning from the Columbus Division of Water. 

The only neighborhoods affected are Grandview Heights, Grove City, Hilliard, Lincoln Village, Marble Cliff, Upper Arlington, Urbancrest and Valleyview. 

The increase in nitrate levels is most likely due to storm water runoff from last week's storm. 

Those younger than six months or who are pregnant are warned to avoid tap water, and to instead use bottled water.
