Quantification of Airborne Biological Contaminants Associated with Land-Applied Biosolids
Greater than 50% of all class B biosolids produced in the US are reused by application to agricultural land. The goal of this research was to pair a comprehensive literature review with a field...
Fate of Pharmaceuticals and Personal Care Products Through Municipal Wastewater Treatment Processes
Municipal wastewater treatment facilities were not specifically designed to remove xenobiotics such as endocrine disrupting compounds (EDCs) and pharmaceuticals and personal care products (PPCPs...
Agronomic and Environmental Availability of Biosolids-P (Phase-II)
Concerns about water quality degradation resulting from land appliation of manures and biosolids have elicited a wide array of national and state regulations. The regulations focus on P as the...
Application of a Dynamic Model to Assess Microbial Health Risks Associated with Beneficial Uses of Biosolids
Microbial risk assessment is a structured approach to estimating risks associated with environmental exposure to pathogens by using available environmental data.
In this report the...

Examination of Reactivation and Regrowth of Fecal Coliforms in Anaerobically Digested Sludge
In a recent study of anaerobically digested solids from seven wastewater treatment facilities, counts of fecal coliform bacteria increased after dewatering at four of the facilities tested....
Comparative Evaluation of Sludge Reduction Routes
This project aims at the evaluation of eight various routes that potentially may allow wastewater treatment plants to produce less sludge (from 5% to 100%).
It has been possible to define...
Determine the Effect of Individual Wastewater Characteristics and Variances on Primary Clarifier Performance
The Water Environment Research Foundation sponsored a one-year study quantifying the effect of certain wastewater characteristics and their variability on the performance of primary clarifiers. ...
Accounting for Toxicity Test Variability in Evaluating WET Test Results
Characterizes sources of WET test variability and evaluates existing and new methods that integrate variability into decision making. Will identify technically defensible methods to improve the...
Membrane Bioreactors for Anaerobic Treatment of Wastewaters (Phase II)
Anaerobic biological treatment systems can offer a number of advantages over their aerobic counterparts. The operational costs associated with anaerobic systems are typically lower than with...
