Well Water: Safety and Quality
by Nur Maisara
Why you should assess your water regularly?
Unlike public water systems, private water supply testing is the voluntary responsibility of the homeowner. There are no government agencies or programs that routinely test private water systems for homeowners.
Surveys indicate that about half of the private water supplies have never been tested.
Additional studies have found that about 50 percent of private water systems fail at least one drinking water standard.
Many pollutants found in private water systems have no obvious symptoms and can only be detected through laboratory testing.
Water testing is generally economical and convenient with many testing laboratories located throughout the state.
Water testing provides vital information to document the quality of your drinking water. Data from previous tests may be necessary if you ever need to prove in court that a nearby land use has damaged your drinking water quality.
The only way homeowners can be certain that their water is safe to drink is to have the water tested periodically.
Water Tests Parameters:
Color in water may be due to the inorganic ions, such as iron and manganese, humus
and peat materials, plankton, weeds and industrial waste.
Odor is recognized as a quality factor affecting acceptability of drinking water. Most
organic and some inorganic chemicals contribute odor.
The turbidity in water is the reduction of transparency due to the presence of particulate
matter such as clay or slit, finely divided organic matter, plankton or other microscopic
The intake of manganese can be high as 20mg/day without apparent ill effects . It should
be noted that manganese may be objectionable to consumers if it is deposited in water
mains and causes water discoloration.
Anaerobic ground waters may contain iron up to several milligrams per liter without
causing discoloration or turbidity in the water.
Calcium is the major constituent of various types of rock. It is one of the most common
constituents present in natural waters ranging from zero to several hundred milligrams per
