Dear Jim - this is an excellent question.
A general mineral analysis including nitrate plus coliform bacteria is a great place to begin. For homes near service stations, industry, agriculture, or a major freeway you would also want to analyze for organic compounds, heavy metals, pesticide sprays and weed killers as well. A general mineral analysis and bacteria should be performed once a calendar year or in the event your water changes in physical appearance suddenly.
A general mineral test would include calcium, magnesium, chloride, nitrate, potassium and sodium in addition to metals such as iron and manganese. If you're encountering stains or sediment, a general mineral analysis will indicate what is producing the problem. If the water contains a funny taste or odor a general mineral analysis with bacteria will often tell you why you have the condition. These tests show if the water is going to be corrosive to pipes, or form mineral scale in your piping, as well as the levels of minerals and salts. If you are having problems with color in the water or brown staining additional tests for tannins is suggested.
Coliform bacteria are living in top soil, on vegetation and also in surface water. Coliform are also found in the intestinal tract of warm-blooded animals and their fecal matter are called E.coli. A number of strains of coliform bacteria can survive for long periods of time in soil and water and can be transported into well casings by insect pests. Coliform bacteria are the most commonly encountered contaminants found in private water systems. Private water wells really should be tested at least once per year for bacteria. However, bacteria are only one of many possible contaminants.
Lead and Copper
Testing for lead and copper should be done on first-draw water which has been dormant in the distribution pipes for no less than 6 hours. In the event that lead and copper concentrations are excessive due to domestic plumbing, they can generally be reduced to tolerable levels by purging the tap for just a few minutes before collecting water for drinking.
Nitrate forms when nitrogen from fertilizers, animal wastes, septic systems, city and county sewage sludge, decaying plants along with other sources combines with oxygenated water. In babies under 6 months old, nitrate exposure may cause a life threatening condition called methemoglobinemia or blue-baby syndrome. Infants with this problem need urgent medical care given that it can lead to coma and death.
Test for nitrate in cases where a pregnant woman or infant is going to be drinking the water. Everyone should get their water tested for nitrate at least one time. If you reside in an area within mile of a corn, soybean or vegetable field, it is best to test your water for nitrate regularly. Well owners should also test for nitrate regularly if their well is situated near a location where fertilizers are produced; or animal feed lots.
Solvents, Gas and Oil
Household and industrial solvents, gasoline and fuel oil are examples of volatile organic chemicals known as VOCs. A number of VOCs tend to be somewhat non-toxic, while some may cause cancer, birth defects and reproduction complications. Fuel oil and gas can enter groundwater as a result of a leaking storage tank or perhaps an old oil spill. Wells that are located within ?mile of an active or abandoned gasoline station, house or farm fuel tank or bulk storage tank have about a greater possibility of being polluted and really should be analyzed one or more times for VOCs.
Paint thinners, dry cleaning chemicals as well as industrial solvents can easily get into well water as a result of spills, improper disposal, leaking storage tanks as well as landfills. Water wells which are located close to a land fill, dry cleaner, automobile repair shop or possibly industrial sites where solvents are used ought to be analyzed for VOCs.
Pesticides and Herbicides
Insecticides are chemical substances employed to control unwanted weeds as well as insects. A number of these now have entered groundwater on account of their use on farm fields. Others have been found in groundwater because of spills and improper disposal. Long-term use of drinking water that contains pesticide by-products may well increase your likelihood of acquiring cancers and other serious health problems.
If your well is situated near corn, soybean or vegetable fields, you need to test your well water for pesticides or herbicides. You should also consider a pesticide test if your well close to where pesticides are produced or stored. Well owners who are unclear about the use of pesticides or herbicides in their area may also want to consider getting their water tested at least one time for these contaminants.
