Water Problems

     Does your water have taste and/or odor problems? Objectionable Chlorine and trihalomethanes the by-product of chlorination? Are there chemical contaminants such as pesticides, herbicides, oil, PCB’s, TCE, gasoline and their derivatives (MTBE) … in your water? Is there bacteria such as giardia, cryptosporidium. Is there radon and lead from household plumbing?
     More and more we are made aware of the negative environmental changes which affect our health through the water we drink, cook with, and bath in.
     Most Americans ingest trace amounts of harmful contaminants through their drinking water daily. These contaminants can have adverse health effects. Some contaminants are carcinogenic which can affect the nervous system and retard learning in children.

Technical Information -Types of Contaminants

     The EPA, in the Safe Drinking Water Act, identifies two major groups of contaminants – PRIMARY contaminants and SECONDARY contaminants. PRIMARY contaminants are those which may directly affect an individual's health. SECONDARY contaminants are those which have aesthetic affects on the quality of life.

Primary (Health) Contaminants

1. INORGANIC CHEMICALS: This group includes metals such as: lead, mercury, metalloids; arsenic and selenium, as well as non-metals' nitrate, nitrite and fluoride.                                                                                                                                                
2. VOLATILE ORGANIC CHEMICALS:This group includes petroleum based products, chemicals and industrial solvents, and all have the potential to be dangerous to our health. Most are considered carcinogenic or probable carcinogens. Benzene, ethylbenzene and methyl-tertiary-butyl-ether (MTBE) are ingredients in gasoline and other fuels. TCE and PCE are used in dry cleaning solvents and cleansers. Trihalomethanes are the by-products of chlorine and chloramine used in public water supplies to kill bacteria.
3. PESTICIDES AND HERBICIDES:These are the most misunderstood and publicized group of chemical contaminants as well as the most diverse. There are thousands of different pesticides and herbicides that are listed and registered in the US and many have a long environmental life span.
4. BIOLOGICAL CONTAMINANTS:This group consists of coliform bacteria, giardia cysts, cryptosporidium and some viruses.

Secondary (Aesthetic) Contaminants

1. HARDNESS in the form of dissolved calcium and magnesium can shorten the life span of water appliances such as dishwashers, washing machines, and water heaters. It also increases the amount of soap and detergents needed for cleaning tasks.
2. METALS such as iron and manganese may cause staining of fixtures and laundry. Manganese may also contribute to unpleasant odors and taste.
3. Ph, the measurement of acidity in water, is considered within normal range by EPA between 6.5 to 8.5. Ph below 6.5 can result in costly plumbing repairs and ingestion of heavy metals (lead, copper, etc.) when drinking the water.
