Water QualityFrequently Asked Questions
What does the Water Quality Summary I get in the mail mean? The Water Quality Summary that you receive in the mail is a report of the presence or absence of organic, inorganic and bacteriological contaminants detected in a sample of drinking water collected at a certain time and place and analyzed by a laboratory. The laboratory may provide the results in terms of concentration of the contaminant per volume of water (usually milligrams or micrograms per liter of water). Another way in which analytical results of this type are reported are in units of "parts per million" (ppm) or "parts per billion" (ppb). Are there laboratories in the area I can call to have these analyses performed? A listing of the laboratories in the general area approved to perform drinking water analyses by the California Department of Health Services can be obtained by clicking here. Coliform Bacteria What are coliform bacteria? Coliforms are a group of bacteria which are readily found in soil, decaying vegetation, and animal feces, and are commonly used as "indicator organisms" in water microbiological analyses.

Contaminant Common Indications of Presence
Hydrogen Sulfide Rotten Egg Odor
Excess Iron Reddish Brown Stains
Iron Bacteria Foul Taste and Odor
Manganese Blackish Stains, Metallic Taste
Hardness White Deposits, Increased Soap Usage Salinity Salty Brackish Taste
Corrosiveness Blue-green Stains and Bitter Taste
Turbidity Cloudy or dirty water Sediment Material Settling out of Water
While none of these contaminants are considered health hazards, there are water treatment systems available designed to remove or reduce them. Contact a professional water treatment company for more information. Also, man-made chemicals, such as pesticides, solvents, etc., can easily leach into a subsurface water supply through careless handling and dumping. Fortunately, these forms of contamination are rarely found in this area.
