The third edition of the Guide to Ship Sanitation presents the public health significance of ships in terms of disease and highlights the importance of applying appropriate control measures. It is intended to be a basis for the development of national approaches to controlling the hazards, providing a framework for policy-making and local decision-making. It may also be used as a reference for regulators, ship operators and ship builders as well as for assessing the potential health impact of projects involving the design of ships.

"This manual is a joint document generated by Environment Canada and the B.C. Ministry of Water, Land and Air Protection under the Canada-British Columbia Water Quality Monitoring Agreement. It summarizes standard water quality sampling procedures, to be used in training and auditing and as a reference for sample collectors. This manual outlines the measure used to assure that all samples collected best represent water conditions at the time and location of sampling. The procedures in this manual have been summarized from operational protocols of the Water and Air Monitoring Section of the Ministry of Water, Land and Air Protection and the Aquatic Sciences Section of Environment Canada. These protocols are updated as changes in procedures occur, and are the ultimate reference"--Preface, p. iii.

Legionnaires' disease, a pneumonia caused by the Legionella bacterium, is the leading cause of reported waterborne disease outbreaks in the United States. Legionella occur naturally in water from many different environmental sources, but grow rapidly in the warm, stagnant conditions that can be found in engineered water systems such as cooling towers, building plumbing, and hot tubs. Humans are primarily exposed to Legionella through inhalation of contaminated aerosols into the respiratory system. Legionnaires' disease can be fatal, with between 3 and 33 percent of Legionella infections leading to death, and studies show the incidence of Legionnaires' disease in the United States increased five-fold from 2000 to 2017. Management of Legionella in Water Systems reviews the state of science on Legionella contamination of water systems, specifically the ecology and diagnosis. This report explores the process of transmission via water systems, quantification, prevention and control, and policy and training issues that affect the incidence of Legionnaires' disease. It also analyzes existing knowledge gaps and recommends research priorities moving forward.
