WATER MICROBIOLOGY
INTRODUCTION TO WATER MICROBIOLOGY
Water microbiology is the study of microorganisms-such as bacteria, viruses, fungi,
and protozoa-that exist in water. These microorganisms play a crucial role in aquatic
ecosystems, influencing water quality, public health, and environmental stability.
Microbial communities in water can be beneficial, contributing to nutrient cycling and
wastewater treatment, or harmful, causing waterborne diseases like cholera,
dysentery, and giardiasis. The presence of pathogenic microbes in drinking water,
recreational waters, and wastewater is a major public health concern, requiring
regular monitoring and treatment processes such as filtration, chlorination, and
ultraviolet (UV) disinfection.
Advancements in water microbiology have led to improved detection methods for
harmful microbes, better water purification techniques, and a deeper understanding of
microbial interactions in aquatic environments. By studying water microbiology,
scientists and engineers help ensure safe and sustainable water supplies for
communities worldwide.
NATURAL SOURCES OF WATER
Water is a universal solvent. Natural sources of water include:
a. Atmospheric H2O (rain, etc.)
b. Surface water (rivers, lakes, stored water - stagnant)
c. Groundwater
Movement of H2O via hydrological cycle: Evaporation, precipitation, deep water
circulation, etc.
Microorganisms in water originate from organic waste, dead plants & animals. When
they find favorable conditions, they multiply & increase in number.
