Abstract Monitoring of water contaminants is essentially required in order to
ensure a continuous supply of potable water, as well as, for ensuring protection of
aquatic and marine environment. Numerous sensing techniques have been developed, though the key aspect of all of them is the material used for detection.
Nanomaterials, and in particular the nanofibers have an edge over other available
alternatives owing to the fact that they offer higher sensitivity, ease of design, faster
response and recovery as well as high specificity. In the present chapter, we
summarize the recent progress in Nanofiber based Sensors for water pollutant
identification and monitoring. It reviews the different available nanofiber chemistry
and a comparison vis-à-vis their sensing characteristics is presented. The chapter
also reviews the fabrication methodology of the various different types of available
sensors based on nanofibers for water monitoring. The role of nanofibers for water
contaminant monitoring is discussed and its efficiency presented.

1 Introduction
Ecosystem balance is a prerequisite for the survival of humankind on earth. There
are a variety of ways in which we have been disturbing this balance for our vested
interests in a bid to bring about the industrial and economic growth. Water is the
lifeline of our society and also a major driving force for maintaining the balance in
