Cadmium removal and sorption by benthic microbial biomats and potential applications for a contaminated watershed in the Arequipa region of southern Peru
… treatment studies using benthic microbial biomats. Several metals of concern were identified, including arsenic, boron, cadmium, copper, lead, nickel, and zinc, occurring at concentrations above permissive limits for water quality, such as agricultural use. Cadmium was selected as a model …

Increased Effluent Dosage Effects on Septic System Absorption-field Products of Differing Architecture Types
… (PA)] on in-product solution storage and biomat thickness in a profile-limited soil, and to identify the long-term acceptance rate (LTAR) of each product. During Phase I of this study (i.e., March 13 to October 4, 2013), effluent loading rates were approximately doubled from the maximum …

Evaluation of the Effects of Absorption Field Product Architecture Type on Effluent Dispersal and Soil Chemical Properties in a Profile-Limited Soil
… May 2010 and January 2012, the thickness of any biomat formation was also measured approximately weekly. Soil samples were collected at the time of installation in 2008 and after > 2 years of effluent dosing in 2011 at the infiltrative surface (i.e., 45- to 55-cm depth) and were analyzed for pH, …

Towards a mechanistic understanding of contaminant attenuation and greenhouse gas emissions in open-water engineered wetlands
… geotextile liner select for a benthic microbial biomat with parallels to periphyton biofilms in shallow streams. This dissertation aims to disentangle the microbial interactions that govern contaminant biotransformations and greenhouse gas emissions within this benthic biomat community, …

Using palm-mat geotextiles for soil conservation on arable loamy sands in the United Kingdom
… runoff control and sediment entrapment, biomat buffer zones may considerably alter and protect flow direction by presenting barriers and creating several cross-drains. Except Borassus completely-covered plots, all plots had significant (P<0.05) increases in topsoil (0-5 cm) bulk density …

The Search For Volatile Biogenic Emissions In Geothermal Areas
… analysis indicate that the naturally occurring biomats are more complex than laboratory cultures and that the observable results of the behaviors of the two groups cannot be directly related. Lastly, other data collected (water chemistry and weather data for the springs) and the results of water …

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 …
