Modeling Onsite Wastewater Systems at the Watershed Scale: A User's Guide

摘要

The guide focuses on modeling transport and fate of the nutrients nitrogen (N) and nphosphorus (P) because these are the most common OWS constituents of concern, and because nboth N and P are regulated in surface waters, while N is also regulated in groundwater. However, nmost of the modeling recommendations and methods described here are relevant for all water-nquality constituents, including emerging organic compounds and microbial pollutants. Before an naccurate chemical-transport model can be developed, reliable models for hydrology and sediment ntransport must be constructed, which is also covered by the guide.
