COLIFORM ORGANISMS:
The presence of harmful bacteria discharged in the waste excretions of men and animals is indicated by the
laboratory test for coliform organisms. Their presence is evidence that the water may have been contaminated
by sewage discharge and may contain dangerous disease-producing organisms. Whenever a well is contami-
nated by coliform organisms, the cause must be located and corrected. When the cause has been corrected,
the following disinfectant procedure may be effective in killing bacteria:
1. Add one-half gallon of chlorine bleach to the well.
2. Allow the bleach to remain in the water overnight. Do not use the water during this period.
3. In the morning, flush the water thoroughly from all taps until there is no longer any odor of chlorine.
4. Collect a sample for retesting in a bottle containing a dechlorinating agent available from the labor-
atory. Follow instructions for Sample Collection provided by the laboratory.
Continuous chlorination is not recommended. Serious bacterial contamination may be accompanied by deter-
gents and bad taste or odor.
DETERGENT POLLUTION:
Detergent pollution is indicated by the MBAS test. Detergent in ground water frequently comes from poor
sewage disposal methods in the vicinity of the well. The cause of detergent pollution must always be cor-
rected. Detergents can be removed from water by activated carbon filters.
IRON AND MANGANESE:
High iron and manganese levels may be caused by rusty pipes, water storage tanks, or pumps. The color
and turbidity of water containing high levels of iron and /or manganese will frequently be above acceptable
ranges. Iron and manganese levels oftentimes are high in new plumbing systems. Vigorous flushing or the
chlorine disinfectant procedure described above under COLIFORM ORGANISMS may bring the levels of iron
and manganese within acceptable ranges. Water of low pH may result in high iron and manganese levels.
In this case, the use of other material in the plumbing systems (plastic or galvanized iron) or water treat-
ment may be necessary.
NITRATE AND NITRITES:
Nitrates get into well water from sewage disposal and from fertilizers applied to soil. Nitrates above 10.0
mg/I and nitrites above 1 mg/I are unsafe for infant feeding and nursing mothers. The best form of control
is removal of the contaminating source. Removal by treatment is expensive and difficult and must be under-
taken by a qualified water treatment specialist.
AMMONIA:
Ammonia levels in excess of acceptable ranges may result from recent contamination by decaying vegeta-
tion or other organic matter. Small levels of ammonia are naturally present in surface and groundwater and
in waste-water. In evaluating the cause of contamination of well water, the laboratory will frequently make
use of the ammonia level in combination with other tests (nitrate, nitrite, MBAS, coliform organisms, etc.).
SODIUM AND CHLORIDES:
Sodium is frequently combined with chloride in water.When chloride levels are over 30 mg/l, the laboratory
will test for sodium. Well water near the ocean may have high sodium and chloride levels. The salting of
roads for winter time deicing, the storage of salt for this purpose, and the discharge from water condition-
ers are common causes of sodium and chloride contamination. Drinking water with sodium levels in excess
of 20 mg/I is not recommended for persons on sodium restricted low salt diets. A physician should be
consulted for further information on the harmful effects of sodium. Since standard water treatment methods
do not remove sodium, care should be taken to remove the cause.
ADDITIONAL LABORATORY TESTS:
The laboratory has a large number of additional tests designed to evaluate water pollution problems. For
further information, please contact qualified laboratory personnel.
