various reasons for a property
owner to test water. Suggest the
following to your clients:
1. Water should be tested if you’re thinking of
purchasing a home and want to assess
the quality of the water supply. It
is also important to know the total coliform
bacteria, lead, iron, nitrate, manganese,
sodium chloride and arsenic
in the water. Hardness and ph level
should also be determined before making
2. Test water if it has an undesirable taste
or smell. This could
indicate the presence of
hydrogen sulfide, pH, copper,
lead, iron or chloride.
3. If the pipes on a home show signs of corrosion,
test the water for lead, iron manganese
4. A test
for hardness is needed if water leaves
soap scum or scaly residue and is
ineffective in cleaning.
5. If contamination is suspected, one should
test for fecal coliform bacteria, nitrate,
chloride and detergents.
6. If using
well water from a well which
is located near an operational or
abandoned gas station or buried fuel
tanks, test for fuel components of
volatile organic compounds. Test
for the same if your water smells
like fuel oil or gasoline.
7. If the well is in an area of intensive agricultural
use, testing for pesticides, coliform
bacteria, nitrates and pH is appropriate.
8. Test for chlorides, sodium and total dissolved
solids if a well is located near
seawater, a roadsalt storage site, or
a heavily salted roadway and the water
is salty to the taste.
hole receptacles –
These receptacles were not
designed to be grounded (though
often the cover plate screw is).
Some older ones aren’t able to be polarized
as well. Modern systems, especially those
serving electronic equipment, are
usually grounded and polarized. Three hole
polarized receptacles can often be adapted
to the older two hole systems as long
as a ground conductor exists. This work
should be done by a professional.
ground fault interrupts –
If a system was installed after
1978, it probably includes
especially sensitive circuit
breakers that are in potential wet
or damp locations, such as the bathroom and
garage. These breakers
trip quickly whenever more
than five milliamps of
leakage to the ground has
been detected. A professional electrician can
retrofit individual devices
if the system predates
