توضیحاتی درمورد کتاب به خارجی
The management of small water supplies presents a unique
challenge globally, in countries at all stages of development.
A combination of lack of resources, limited understanding of
the risks and poor expertise means that individuals and
communities may face serious health risks from these supplies.
This is not only due to microbiological contamination, but also
from contamination by metals, either due to natural or
man-made
contamination of the source water or through leaching from
plumbing materials due to inadequate conditioning and corrosion
inhibition and use of inappropriate materials. This Best
Practice Guide aims to share best practice and experience from
around the world on a practical level. It looks at general
issues relating to small supplies and ways of managing these,
adopting a Water Safety Plan approach to deliver sound and
lasting improvements to quality. Management techniques and
treatment relating to specific metals will be covered, from a
theoretical and practical perspective, to deliver a publication
that will act as an authoritative guide for all those faced
with the problem of ensuring the quality of a small water
supply. Varied case-studies will help to illustrate issues and
ways in which they have been resolved. Table of contents The

Abstract: The management of small water supplies presents a
unique challenge globally, in countries at all stages of

understanding of the risks and poor expertise means that
individuals and communities may face serious health risks from
these supplies. This is not only due to microbiological
contamination, but also from contamination by metals, either
due to natural or man-made contamination of the source water or
through leaching from plumbing materials due to inadequate

looks at general issues relating to small supplies and ways of

techniques and treatment relating to specific metals will be
covered, from a theoretical and practical perspective, to
