What the ground in Lake Hopatcong is like

The USDA soil survey rates mapped ground in Lake Hopatcong for septic drain-field suitability across roughly 7.4 square miles. About 98% of the rated ground is classed "Very limited", meaning the soil has one or more features unfavorable for a conventional drain field, and the limits generally cannot be overcome without major soil reclamation, special design or expensive installation.

In Lake Hopatcong, the leading limit is depth to the saturated zone: the water table sits so close to the surface that a drain field has little dry soil left underneath it. Effluent needs unsaturated ground to treat and disperse; when that column is thin, the field has nowhere safe to go. The survey flags that limit on about 76% of the rated ground here.

The limiting features the survey records most often here:

• Depth to saturated zone76.1%
• Slope76.1%
• Seepage, bottom layer39.1%
• Depth to bedrock10.6%

This is survey data for mapped areas, not a substitute for a site evaluation on your own lot. Conditions on a single parcel can differ from the map.
