What the ground in Glendora is like
The USDA soil survey rates mapped ground in Glendora for septic drain-field suitability across roughly 20 square miles. About 96% of the rated ground is classed "Very limited", the survey records severe restrictions for a conventional drain field across most of that ground.
In Glendora, the leading limit is depth to bedrock: rock sits close enough to the surface that there is not enough soil column above it for a conventional field to sit in. Effluent needs that depth to disperse; when bedrock comes up, the workable layer runs out. The survey flags that limit on about 52% of the rated ground here.
