High plant functional group diversity has been hypothesized to reduce resource concentrations based on the assumption that species from one functional group acquire resources similarly to one another, while species from other functional groups acquire resources dissimilarly. To determine if functional groups use soil nutrients different from one another, we investigated the impact of removing i...

Climate change may affect the ability of soil-based onsite wastewater treatment systems (OWTS) to treat wastewater in coastal regions of the Northeastern United States. Higher temperatures and water tables can affect treatment by reducing the volume of unsaturated soil and oxygen available for treatment, which may result in greater transport of pathogens, nutrients, and biochemical oxygen deman...

Abstract. Soil aquifer treatment (SAT) is an effective and sustainable technology for wastewater or stormwater treatment, storage, reuse. During SAT, the vadose zone acts as a pseudo-reactor in which physical biochemical processes are utilized to improve infiltrated-water quality. Dissolved oxygen (DO) necessary aerobic microbial oxidation of carbon nitrogen species effluent. Therefore, enhance...

It is commonly believed that the composition of groundwater does not change naturally. So if a change is recognized through taste and/or odor, many may think that something bad has happened. Perhaps the aquifer has become contaminated, or something is wrong with the well. However, a common cause of changes in water quality is through natural variations within the aquifer. What gives groundwater...

As one of the artificial recharge technologies, soil–aquifer treatment (SAT) system is used for removal nitrogen pollution from aquaculture wastewater. An adsorption-enhanced SAT was designed to reduce level below threshold stipulated by standards. Adsorption kinetics experiments were measure adsorption capacity zeolite and activated carbon ammonia nitrogen. Both adsorbents can be well describe...

A suite of target endocrine disruptor compounds (EDCs) and pharmaceuticals and personal care products (PPCPs) were evaluated for removal by several water treatment processes at bench-, pilot-, and fullscale. Over 60 different EDCs and PPCPs were chosen and simultaneously evaluated based on structure, occurrence, and potential health impacts. Treatment processes evaluated include physical (e.g.,...
