Guidelines For Drinking-Water Quality Management For New Zealand Chapter 5: General Microbiological Quality
Drinking Water Guidelines Chapter 5 General microbiological quality
Source : https://www.health.govt.nz/
Introduction
This chapter discusses the microbiological quality of drinking-water in general terms. Microbiological compliance issues are discussed as follows:
• Chapter 6: Bacterial Compliance
• Chapter 7: Virological Compliance
• Chapter 8: Protozoal Compliance
• Chapter 9: Cyanobacterial Compliance.
Infectious, water-related diseases are a major cause of morbidity and mortality worldwide. Newly-recognised pathogens and new strains of established pathogens are being discovered that present important additional challenges to both the water and public health sectors. Between 1972 and 1999, 35 new agents of disease were discovered and many more have re-emerged. Amongst these are pathogens that may be transmitted by water (WHO 2003b). There are suggestions that giardiasis was spread around the world by the mobility of armed forces during WWII. The first case of human cryptosporidiosis was reported in 1976, and by 1985 this ‘new’ pathogen was becoming more widely recognised.

Investigation of The Quality of Water Treated by Magnetic Fields
Abstract
Passing water through a magnetic field has been claimed to improve chemical, physical and bacteriological quality of water in many different applications. Although the treatment process has been used for decades, it still remains in the realms of pseudoscience. If the claims of treating water with magnets are true, the process offers improvements on many of our applications of water in today’s world. A large number of peer reviewed journal articles have reported contradictory claims about the treatment.. Some of the most beneficial claimed water applications from magnetically treated water include improvement in scale reduction in pipes and enhanced crop yields with reduced water usage. Today we are still unsure whether the technology works and those who do believe it works are still trying to understand the mechanisms of how it works. Many research papers are starting to develop similar theories behind the mechanism of the treatment. From previous studies, it has been determined that the most successful MTD’s are those with alternating poles. The majority of the experiments performed during this research were determined to have insufficient controls to produce conclusive results. The conclusions from this research were focused on designing improved experiments to provide more conclusive results. A theory was developed to explain the MTD’s mechanisms of scale reduction. While the experimental results were not conclusive, the results attained backed the theory. Magnetically treated water does not do all that it is claimed it does. However, some of the positive results obtained during this research suggest that the improved experiments developed from this research may provide conclusive results on this controversial topic.

Effect of the Quality of Water Used for Dialysis on the Efficacy of Hemodialysis
Abstract
The quality of the water used for dialysis has been suggested as a factor causing inflammation in patients on hemodialysis (HD). We therefore conducted this study to identify the effect of quality of the water on nutritional state, inflammation and need for human recombinant erythropoietin (EPO) in patients undergoing HD at Agadir, Morocco. This prospective study included patients on HD for at least one year. The water treatment was done according to the standard protocol, which was followed by additional enhancement of ultrafiltration using an additional polysulfone filter (diasafe, Fresenius, Bad Homburg, Germany) before the dialyser. Water was monitored regularly during the study period to ensure acceptable levels of bacterial count as well as endotoxin levels. Various parameters including dry weight, systolic and diastolic blood pressure (PA) before and after an HD session, need for human recombinant EPO, levels of hemoglobin (Hb), albumin, ferritin, C-reactive protein (CRP), and the dose of dialysis delivered (Kt/V) were measured first at the beginning of the study and thereafter, in the third, sixth and 12 th months of the study. The study involved 47 patients, and after 12 months of the study, an improvement in median dry weight (1.2 kg, P = 0017) and a simultaneous median reduction of 20.7 IU/kg/week of EPO, with an in-crease of the median level of Hb, was noted. The results of our study suggest that by improving the biocompatibility of HD with the use of good quality water, patients acquire a better nutritional, inflammatory and hematologic status.
