One of the many issues we are facing in our waters is saltwater intrusion and salinization. Saltwater intrusion and salinization is defined as the increase of chloride ion concentrations in freshwater aquifers or more simply put the movement of saline water into freshwater aquifers. When fresh water is withdrawn at a faster rate than

Formation of Hydrocarbons Types of hydrocarbons Parameters for hydrocarbon accumulation Phases of alteration of organic matter Types of kerogen Migration of hydrocarbons Five Major Types of Hydrocarbons Kerogen: Kerogen is a fine-grained‚ amorphous organic matter. It is not soluble to normal petroleum solvents‚ like carbon disulfide. Its chemical composition is 75% C‚ 10% H‚ 15% other (sulfur‚ oxygen‚ nitrogen‚ etc.). It is very important in the formation of hydrocarbons because it is what generates

sunlight can reach deeper into the water; this lets more aquatic animals to grow.

Crayfish – also called crawfish‚ crawdads‚ freshwater lobsters‚ or mudbugs – are freshwater crustaceans resembling small lobsters‚ to which they are related; taxonomically‚ they are members of the superfamilies Astacoidea and Parastacoidea.
