Taste and Odor: The smell of water often gives some indication of its character.<br />
Generally, odor and taste are present in combination when water is sampled from runoffs<br />
for testing. The primary sources of taste and odor problems in runoff water are biological<br />
contaminants that originate from domestic and industrial wastes. However, other<br />
anthropogenic sources such as wastewater discharges and chemical spills also act as<br />
sources of chemicals that cause off tastes and odors. Such chemicals can affect both water<br />
quality and rainwater harvesting system equipments. In most cases, water runoff paths<br />
traverse on a number of naturally occurring compounds and minerals such as calcium, iron<br />
and magnesium in varying concentrations that have an effect on the waters’ taste.<br />
