How Healthy is the South River?

The Arundel Rivers Federation measures many different parameters to learn about the water quality of the South River. We hope this map helps answer three basic questions about the health of the South River: Is it safe to swim? Can fish breathe? How dirty is it?  For the purposes of this map, we have assigned a parameter for each question.

• Bacteria levels help determine whether it is safe to swim.
• Dissolved Oxygen levels show how well fish can breathe.
• Water Clarity helps measures the amount sediment (dirt), which is our worst pollutant in terms of causing harm to aquatic life.

Restoration Projects: Since sediment and excessive nutrients are our two worst pollutants, the Federation has been actively constructing projects that work to trap and filter those pollutants before they reach the South, West, and Rhode Rivers. Please check out our projects that range from tiny rain gardens to multi-million dollar stream restorations.
