What is the typical pH range of groundwater in Iowa?

The typical pH range of groundwater in Iowa is usually between 6.5 to 8.0. This range indicates that Iowa's groundwater is generally neutral to slightly alkaline. A pH level within this range is important for maintaining the health of aquatic ecosystems, as well as for the usability of the water for agricultural purposes and drinking.

Groundwater in the 6.5 to 8.0 range is ideal for the dissolution of minerals, which helps provide essential nutrients and maintains a balanced environment for plant growth. When the pH levels drop below 6.5 or rise above 8.0, it can lead to various environmental issues, including difficulties in nutrient availability and increased toxicity for aquatic life. This makes understanding and monitoring groundwater pH crucial for effective environmental management and agricultural practices in Iowa.
