Trihalomethane

When chlorine is added to water with organic material, such as algae, river weeds, and decaying leaves, THMs are formed. Residual chlorine molecules react with this harmless organic material to form a group of chlorinated chemical compounds, THMs. They are tasteless and odorless, but harmful and potentially toxic. The quantity of byproducts formed is determined by several factors, such as the amount and type of organic material present in water, temperature, pH, chlorine dosage, contact time available for chlorine, and bromide concentration in the water. The organic matter in water mainly consists
of a) humic substance, which is the organic portion of soil that remains after prolonged
microbial decomposition formed by the decay of leaves, wood, and other vegetable matter; and  fulvic acid, which is a water soluble substance of low molecular weight that is derived from humus. hope this works or tell me what exactly u are looking for, i may be of some help..cheers
