CHARACTERIZATION OF SEPTIC SYSTEM WASTEWATER AND MUNICIPAL SOLID WASTE LANDFILL LEACHATE
… for waste management and the protection of ecosystem, surface water, and groundwater resources. In the U.S., most domestic solid waste is disposed of in landfills, and domestic wastewater is treated by wastewater treatment plants (WWTPs) or onsite wastewater treatment systems (OWTSs). While …

Location of Septic System Failures in Southwest Missouri Using False Color Infrared Photography
Locating septic system failures with false color infrared photography is a viable method of environmental evaluation that can be used as part of an education program designed to increase public and official awareness. Septic system failures are a problem in southwest Missouri due to their extensive …

Increased Effluent Dosage Effects on Septic System Absorption-field Products of Differing Architecture Types
… approximately 20% of all homes use an on-site septic system as a form of household wastewater treatment. Since karst features are prevalent throughout the Ozark Highlands region of Northwest Arkansas, surface and groundwater resources are susceptible to contamination. Therefore, the objectives …

The Spatial Relationship Between Septic System Failure and Environmental Factors in Washington Township, Marion County, Indiana
Underground septic systems thrive or fail based on the relationship with their local environment. This paper explores ways environmental variables such as soil type, tree roots, degree of slope, and impervious surfaces affect on-site wastewater treatment systems. It also discusses the effects each …

Response of a cave aquatic community to groundwater pollution
… in reference pools and pools disturbed by septic system effluent in Banners Corner Cave, Russell Co., Virginia. Data from six physicochemical parameters indicate slight to high disturbance in five pools in reference to two undisturbed sites. Disturbed sites had high levels of conductivity, …

Predicting and Equipping Private Well Owners at Risk of Microbial Contamination After Flooding Events in the Alabama Black Belt
… monitor and maintain the health of their private systems. Although groundwater is generally low in contaminants, septic system failures due to soil conditions combined with flooding from frequent storms have created a groundwater quality epidemic in the Black Belt region of Alabama.Floodwater can …

Denitrification as a means of addressing nitrate-contaminated groundwater on Cape Cod, Massachusetts
… and the majority of homes and businesses rely on septic systems. Increased urban development has increased the frequency of installation of septic systems. In many locations, the density of septic systems is greater than the natural ability of the subsurface environment to receive and purify …

Denitrification of anthropogenic nitrogen in groundwater : measurement and modeling using stable isotopic and mass balance approaches
… groundwater at two forested field sites and in a septic system plume. These sites provided a large range of groundwater nitrate and dissolved organic carbon (DOC) concentrations. At all sites, denitrification rates increased with increasing nitrate concentration. First order denitrification rate …

Agricultural Contaminant Source and Transport in a Karst Groundwater Basin
… nitrates was from ammonium fertilizers and from septic system wastes. Atrazine, at levels well below the MCL standards established by EPA, and its metabolite deethylatrzine (DEA) were detected in the groundwater year round. Contaminant load was calculated for nitrates, bacteria, and atrazine. …

Changes in Septic Tank Effluent Due to Water Softener Use
The compatibility of home water softeners and septic tanks is of concern for the on-site wastewater treatment community. Research has shown that high sodium levels in activated sludge plants can lead to deflocculation and poor effluent quality. Therefore, it is logical to assume that high sodium …

Auxiliary Procedures for the AGNPS Model in Urban Fringe Watersheds
… This study involved using geographic information system (GIS) spatial data and functionality to improve the spatial and temporal assignment of parameter values for the AGNPS 5.0 model and incorporated methods for representing urban fringe land uses and their nonpoint source (NPS) pollution …

Evaluation of the Effects of Absorption Field Product Architecture Type on Effluent Dispersal and Soil Chemical Properties in a Profile-Limited Soil
<p>On-site wastewater treatment systems (OWTSs) are commonly used by households in areas of low population density to treat household wastewater and recycle it back to the environment. The traditional absorption field product used in OWTSs is a pipe-and-gravel architecture type, which has been used …
