ABSTRACT A large population living in suburban and rural areas in the world uses septic
systems, also called onsite wastewater treatment systems, to dispose of household …

Linking fecal indicator bacteria concentrations in large mixed-use watersheds back to diffuse
human sources, such as septic systems, has met limited success. In this study, 64 rivers that …

Environmental problems such as eutrophication caused by excessive nutrient discharge are
global challenges. There are complex pollution sources of nitrogen (N) discharge in many …

Precipitation is one of the most important drivers in watershed models. Our objective was to
compare two sources of interpolated precipitation data in terms of their effect on calibration …

Despite the significant role of precipitation in the hydrological cycle, few studies have been
conducted to evaluate the impacts of the temporal resolution of rainfall inputs on the …

Dissolved organic carbon (DOC) in surface water influences the global carbon cycle,
ecosystem productivity, and water quality in potable water supply systems. Few physically …

Although multiple pollution sources could discharge significant nutrient loads within a river
basin, few studies have attempted to analyze the spatiotemporal distribution patterns of …

Onsite wastewater treatment systems (OWTS), commonly known as septic systems, are
increasingly recognized as a potential source of nitrogen in the shallow groundwater. Our …

Our book addresses the needs of practitioners, engineers, scientists, regulators, resource
managers, planners, and others with a need to know about septic systems. It arose after …

Nitrogen inputs to coastal watersheds have been linked to eutrophication. However, the role
that domestic sources of wastewater play in contributing nitrogen to coastal watersheds is …
