Nitrate Levels Rising in Area Rivers
CEDAR RAPIDS, IA (CBS 2/FOX 28) -- The Cedar Rapids Water Division is keeping watch as nitrate levels in the Cedar River rise. Officials say the increase is not uncommon during the spring planting season when wet weather pushes some of the nitrogen fertilizer into area waterways.
Last weekend, The United States Geological Survey measure one of the highest nitrate levels ever recorded in the Cedar River.
Experts say part of the problem is there was a lot of nitrate left in the soil because of last year's drought.
The Cedar Rapids Water Division says it's closely monitoring the levels in the river and in the city's drinking water. If the nitrate levels approach unsafe levels, the city will notify the public and the Iowa Department of Natural Resources.
