What the ground in Hanford is like

In Hanford, the leading limit is slow water movement: effluent does not drain through the soil fast enough, so a conventional field can back up or pond when the ground cannot keep pace. The survey flags that limit on about 90% of the rated ground here.

The limiting features the survey records most often here:

• Slow water movement89.6%
• Filtering capacity3.1%
