| Aluminum | Importance: Causes metallic-tasting water. Sources: Some naturally occurrinng |
| Arsenic | Importance: May cause cancer and produce other serious health effects. Sources: Naturally occurring, but most from mining activities. |
| Bacteria (Total Coliform and E. Coli) | Importance: May cause gastrointestinal illnesses and cause water to have bad taste or odor. Sources: Surface water, septic systems and animal wastes. |
| Barium | Importance: May cause hypertension and other health effects. Sources: Mostly from deep brines from gas/oil well drilling; may also occur from industrial activities. |
| Chloride | Importance: Causes salty tasting water; corrosion and blackening of steel. Sources: Mostly Some naturally occurring, but primarily from gas/oil well drilling brines or road salt |
| Copper | Importance: Causes blue-green stains; bitter metallic tasting water; gastrointestinal upset; liver and kidney damage. Sources: Most from corrosion of copper plumbing; more rarely from industrial waste sites. |
| Corrosivity | Importance: Causes metallic-tasting water; blue green stains, leaky pipes in homes with copper plumbing. Sources: Most is naturally occurring; some due to mining activities. |
| Fluoride | Importance: May cause bone damage and discoloration of teeth. Sources: Naturally occurring; present in some industrial wastes. |
| Hardness | Importance: Causes whitish-gray residue when water is heated; decreased life of water heater elements; increased use of soap. Sources: Naturally occurring in many areas, especially where limestone occurs. |
