What the ground in West Chester is like

The USDA soil survey rates mapped ground in West Chester for septic drain-field suitability across roughly 1.9 square miles. About 48% of the rated ground is classed "Very limited", the survey records severe restrictions for a conventional drain field across most of that ground.

In West Chester, 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 32% of the rated ground here.

The limiting features the survey records most often here:

• Slow water movement32.3%
• Large stones24.1%
• Unstable fill24.1%
• Slope23.5%
