PUBLISHED BY THE NATIONAL ENVIRONMENTAL SERVICES CENTER Simultaneous Compliance with Drinking Water Regulations By Zane Satterfield, P. E., NESC Engineering Scientist Summary
"... other, as well as with other regulations such as the Lead and Copper Rule and the Total Coliform Rule. This means that small system operators cannot simply comply with these mandates individually, but must consider how changing their treatment process to meet one rule might affect compliance with ot ..."

with other rules. This Tech Brief provides information and strategies to effectively comply with those regulations that are most likely to conflict with one another. Whack-a-Mole The term “simultaneous compliance ” refers to a situation where addressing one regulation threatens compliance with a different
Response of different types of biosolids to simultaneous dewatering and pathogens inactivation by electrokinetic system. 80th Annual Water Environment Federation
, 2007
"... ABSTRACT Only electrokinetic system and its effect on the inactivation of pathogenic organisms in biosolids were investigated. Bench scale experiments were conducted in a series of electrokinetic (EK) reactors. Ten EK reactors were set up with different types of sewage sludge: primary, secondary (a ..."

. Higher than 6-log reduction of reovirus was also observed in all tested EK reactors. The developed EK process can be applied to different types of sludge in order to upgrade it to Class A biosolids due to simultaneous dewatering and disinfection.
# 2004 British Occupational Hygiene Society Published by Oxford University Press doi:10.1093/annhyg/meh067 Simultaneous Sampling of Peroxyacetic Acid and Hydrogen Peroxide in Workplace Atmospheres
, 2004
"... The use of peroxyacetic acid (PAA) in the disinfection processes in the food industry or for medical purposes is increasing. As it is the product of the reaction of acetic acid (AA) and hydrogen peroxide (HP) and coexists with them, and given the fact that the chemical properties of these two substa ..."

"... ii Disinfectants such as chlorine are used in drinking water treatment to protect the public health from pathogenic microorganisms. However, disinfectants also react with humic material present in raw water sources and produce by-products, such as trihalomethanes. Total trihalomethanes (TTHMs) inclu ..."

/L. Additional regulations require reliable drinking water disinfection for resistant pathogens and treatment plants must simultaneously control TTHMs and achieve proper disinfection. Research has shown that THM formation depends on several factors. THM concentrations increase with increasing residence time
Water Quality Modelling for Drinking Water Distribution Systems
"... Abstract: A dynamic water quality model for drinking water distribution systems has been developed in this study, to include processes that occur in the bulk water, as well as those occurring in the biofilm of a distribution system. The model has been validated against water quality data obtained fr ..."

from extensive experimental studies conducted with biofilm reactors. Protein and carbohydrate densities in the biofilm represent biofilm biomass. This model is able to predict the disinfectant decay due to organic matter in the bulk water, as well as that due to biofilm. It simultaneously predicts
Iodine concentrations in milk
"... Iodine tends to be supplemented at farm level in the expectation of increasing cow health and fertility. There is concern that such practices may result in high milk iodine, which could affect ingredients for infant formula and, thus, dairy export markets. The objective of this study was to quantify ..."
Abstract

disinfection iodine increased milk iodine con-centrations in an additive manner, exceeding common target values of 250 µg/kg. As both iodine treatments can occur simultaneously on farm, supplementation strategies should be monitored.
Quantitative detection and biological propagation of scrapie seeding activity in homogenate (BH; 10%) was diluted 6,250-fold in normal BH (NBH), and a 10 mL aliquot was added to 90 mL fresh NBH in tubes containing no beads, or two EPDM, aluminum oxide, ac

"... Prions are pathogens with an unusually high tolerance to inactivation and constitute a complex challenge to the reprocessing of surgical instruments. On the other hand, however, they provide an informative paradigm which has been exploited successfully for the development of novel broad-range disinf ..."

Here we report on the development of a methodological platform that further facilitates the use of scrapie prions as model pathogens for disinfection. We used specifically adapted serial protein misfolding cyclic amplification (PMCA
