What Contaminants Commonly Exist in Drinking Water?

• Total coliforms and E. coli can be present as a result of nearby septic systems, sewage discharges, and domestic or wild animal fecal matter.

• Heavy Metals naturally occur in groundwater in many regions. Uranium and Arsenic are common metals of concerns in the BC interior. Lead and Copper can be a concerns in homes with brass fixtures, lead solder and copper pipes.

Turbidity assesses suspended particulate in the water. These particles can contain bacteria and viruses. Health risks increases as turbidity rises.

• Agricultural Contamination from nearby farming activities may include nitrogen compounds (nitrite and nitrate) and pesticides or herbicides.

Fluoride occurs naturally in groundwater at concentrations that can cause dental fluorosis: yellowing of teeth, pitting and alteration of tooth enamel. High fluoride levels are known in parts of the Okanagan and Shuswap regions of BC.
