Most of the chemicals used in the drilling fluids for hydro-fracturing are believed to be non-toxic.

However, there are also examples of chemicals used that are toxins and/or carcinogens. These include benzene, toluene, ethyl benzene and xylene. Their use obviously raises concerns.

When water samples are analyzed from well water or other sources, signs it is tainted with fracing fluid chemicals may include unusual readings on:

• alkalinity
• aluminum
• barium
• calcium
• iron
• hardness
• manganese
• pH
• potassium
• specific conductivity
• sodium
• total dissolved solids.
