Examples of (toxic) chemicals used in Hydro-fracturing 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.
