RISRelationship between Groundwater Nitrate Concentration and Density of Onsite Wastewater Treatment Systems: Role of Soil Parent Material and Impact on Pollution Risk
Publisher: American Society of Civil Engineers
Abstract: Nitrate (NO3−) pollution from onsite wastewater treatment systems (OWTS) is a concern in coastal communities that rely on groundwater for drinking water because of health risks associated with high levels of NO3− and the ...
Effects of Sand Depth on Domestic Wastewater Renovation in Intermittently Aerated Leachfield Mesocosms
Publisher: American Society of Civil Engineers
Abstract: The depth of soil below the absorption trench of a septic system is considered an important factor in protection of groundwater. We examined the effects of depth on the ability of intermittently aerated sand-filled leachfield ...
Geospatial Modeling Suggests Threats from Stormy Seas to Rhode Island’s Coastal Septic Systems
Publisher: ASCE
Abstract: Coastal communities preparing for climate change and sea-level rise need to consider the impact large storms will have on belowground infrastructure. Although these communities often rely on on-site wastewater treatment ...
