The objective of the course is to provide students with basic concepts from environmental chemistry and microbiology for understanding and solving environmental problems.
Major topics that will be covered in environmental chemistry are: review of basic concepts in chemistry, concept of chemical equilibria, equilibrium constants and activity, reaction kinetics, acid and basis, polyprotic acids and bases, acidity, alkalinity, carbonate system, pH-Ct, buffers, and solubility reactions, nuclear chemistry, nitrogen chemistry and chlorination.
Major topics that will be covered in environmental microbiology are: Introduction, the bacteria, the fungi, the algae, protozoa and other higher forms, viruses, pathogens and disease, microbial growth and enumeration, control of microorganisms, microbial diversity and metabolic pathways for remediating contaminated water, solid and hazardous waste, and soil.

Sources of Acidity,
CO2 may come from atmosphere and from biological oxidation of organic matter (particularly in polluted water),Mineral acidity (HCl, H2SO4, HNO3) comes from industrial wastes or due to the oxidation of sulfur or sulfides under bacterial action. Combustion of fossil fuel cause the formation of CO2,
Significance of acidity,
Acid waters are corrosive. In many treatment procedures (such as biological treatments) it is important to maintain the pH in range of 6-9.5.
