LPRV Aquifer Management: Water Quality Impacts

In summary, of the many types of potential land-use activities which are of concern in Idaho, three classes are known to represent a threat to water quality in the lower Portneuf River valley aquifer: septic sewage disposal, road and storm water runoff control, and fuel/hazardous materials storage.

A fourth class of activity may also be worthy of consideration: the practice of constructing floor drains to accept waste water in commercial buildings (e.g. in machine shops, service stations) currently is neither effectively regulated or inspected / enforced. By analogy with storm water drain wells, the handling of non-domestic wastewater in such facilities may need to be regulated more effectively to minimize the potential for ground water contamination.
