Many constituents(such as calcium,sodium,or iron)which are often found in drinking water can cause taste,color,and odor problems.The Water Sources: taste and odor constituents are called secondary constituents and are Drinking water sources(both tap water and bottled water)include rivers, regulated by the State of Texas,not the EPA.These constituents are not lakes,streams,ponds, reservoirs,springs and wells.As water travels causes for health concern.Therefore,secondaries are not required to be over the surface of the land or through the ground, it dissolves naturally- reported in this document but they may greatly affect the appearance occurring minerals and in some cases,radioactive material,and can pick and taste of your water. up substances resulting from the presence of animals or from human ac- tivity.Contaminants that may be present in source water before treat Required Additional Health Information for Lead ment include: If present,elevated levels of lead can cause serious health problems, Microbial contaminants,such as viruses and bacteria,which may come especially for pregnant women and young children.
