    f you are a real estate agent representing the buyer or the
   seller, you  may have a question about how you  can  best
   inform your client about private well water issues during a
     property transaction. This brochure will help to answer
     your questions.

According to the US  Environmental Protection Agency, (EPA),
it is  estimated that approximately  2.3 million people, or  20%
of New Englanders, rely on private wells for their drinking water
supply.This percentage  increases to more than  40% for  Vermont,
New Hampshire, and Maine. Contaminants, if present in drinking
water at elevated levels, can pose a  risk to families. Many of the
contaminants that can  be present in a private  well are  odorless,
tasteless, and colorless. The only way to identify their presence is to
have the well water tested.

Knowledge
Is Power!
Advise your client to get the
most information possible from
qualified professionals about
both the well water quality and
the condition and functioning
of the entire drinking water sys-
tem. For testing recommenda-
tions and information about
qualified professionals,  it is best to contact the appropriate state
agency, listed in the For More Information section at the end of
this brochure.

 Short-Term
                e wen nas taste and odor
               ctive buyer may hesitate to
     ;n offer on the property.

Encourage your seller to have the well tested for
bacteria and other problematic contaminants and
install water treatment if needed.
 Long-Term
               [.private well owners should
periodically test their well water to ensure the
quality of their drinking water.
It is best to have the well water tested annually for
at least bacteria, nitrate and nitrite. Other contami-
nants, like arsenic, should be tested for on a less
frequent or as needed basis.
Avoid  Delays!
Testing and inspection prior to listing a property will help avoid
delays in selling the home. Even though the potential buyer's
lending  institution will most likely require testing and inspec-
tion, an inspection commissioned by the home-seller will help
identify any existing problems that should be remedied prior
to listing. This will help to make the home more marketable
and reduce  the risk of problems during the sale. If necessary,
correct any  identified problems. (Note: To ensure public health
protection  in the long-term, state drinking water  agencies
recommend that homeowners arrange to have their private wells
tested annually.)

Safe  water  can  be  a  selling  point!
If there are any objections to testing and inspecting the water
system, you can advise your client that a house with a system
in disrepair or with contaminants present in the water is worth
less money on the market and can take longer to sell. Just like
a home with a new roof will likely sell for more, a home with a
properly functioning water system that provides safe drinking
water is worth more and will be a place of comfort for the new
owners.

-------
What tests should  be conducted?
While  this recommendation may vary from  state to  state,
the EPA suggests that an initial test should include coliform
bacteria, nitrates/nitrites, and pH. In addition, the homeowner
should  consult with experts about the need to test for arsenic,
lead, copper, radon, a gross alpha screen, and volatile organic
compounds. For more information on specific testing
suggestions in your state, contact the appropriate state agency.

The  buyer's lending institution will most  likely require that
the well pass a water quality test prior  to  loan approval.
Most lenders require testing for
bacteria, nitrate and lead at a
minimum. Keep in  mind that
these  tests are intended  to
ensure that the lender is not
making a  loan on a property
with a faulty system, in case they
have to repossess the property.
The  testing is not necessarily
required to protect the health of
the residents.

Where  should the  samples   be  taken?
The water sample should be collected from the cold water kitchen
tap. Most water testing laboratories supply their own sample
containers and provide  detailed instructions on  how to
properly collect a water sample. Use the bottles provided and
carefully follow all instructions to obtain a good sample. In some
cases, a laboratory professional may come to the home and
collect  the sample.                                     3

-------
If there is a home water treatment system, a water test should
be done on both the raw water coming into the house before
the treatment system and a separate test after the water has
passed through the treatment system. This will identify the
contaminants that are present and ensure that the treatment
system is functioning properly.

Are  there  any specific state
testing requirements?
State  requirements for private  well testing at the time of
property sale vary from state to state. It is best to check with the
state drinking water agency for requirements. In addition, your
client can ask  the appropriate state agency  about any known
contamination problems in the area to assist in determining
what contaminants to test for.

Where should the water be  tested?
Your  client should arrange to have the water tested at a
state certified  lab. These labs follow accepted procedures for
testing contaminants.  Make sure that the lab is certified to test
for the contaminants  requested.The lab will provide sampling
instructions and collection bottles for taking the water sample,
or in some cases, may send a professional to the home to collect
the samples. Contact  the appropriate state agency for a listing
of certified labs.

What  else should I  know about
water  testing?
Prior to obtaining a water sample  for testing, advise your client
to confirm that the well has no chlorine in it. The well may have

4

-------
been chlorinated because of a failing bacteria or  other test.
Chlorine would  mask the presence of bacteria  and other
contaminants that may be present in the well water. A pool
chemical  test kit can confirm whether chlorine is present. If
chlorine is present, delay the water test. Remove chlorine from
the well and plumbing by running the water at each  faucet until
no chlorine odor is detected. Wait at least 24 hours after no
chlorine odor is detected before re-testing for the presence of
chlorine and collecting a water sample. Using the pool chemi-
cal test kit prior to sample collection will ensure the continuity
of checking for chlorine each time a sample is collected.

What are  the  costs for testing?
What to test for and how much the test will cost will vary by
state and  lab. Testing can range  from as  little as $5 for an
individual test parameter (like pH) to $250 or more for a  com-
bination of tests covering a wide spectrum of parameters. See
the state drinking water agency contacts for more information.

Once the testing is  done,
how does  my client know the
water  is  safe  to  drink?
The EPA establishes limits on  the concentrations of certain
contaminants that would pose a public health threat if present
in elevated levels in public drinking water supplies.These limits,
or standards, are set to protect public health by ensuring good
quality water. Private well owners are generally not  required to
test their drinking water to meet standards, unless the state has
regulations for private well testing. However, lending compa-
nies may use some of these standards for loan approval. Private
well owners  and potential buyers  can use the public drinking

-------
water standards as guidelines  when evaluating the quality of
private drinking water. For more information on drinking water
quality standards, visit EPA's website: www.epa.gov/safewater
State drinking water agencies may also set advisory levels for
some contaminants, such as sodium, that are either stricter than
the federal standards or  that are not covered by the federal
standards.

Are  there  any other  parts of the  water
system  that  need  to  be  inspected?
Yes. In addition  to a well water test, the mechanical workings of
the water system should also be inspected.This includes the well
pump, pressure tank, water treatment system (should one exist),
the condition of the area around the well, and the well's proxim-
ity to potential  contamination sources.The well  itself should be
inspected to ensure tight construction. Also, the well's location
should not be subject to flooding. It is important to advise your
client  to  rely  on  qualified professionals to conduct  the
inspection. Qualified home inspectors can inspect the plumbing
system, such as general age, appearance and performance of the
piping,  storage  tank and/or other water system appliances like
water filters and treatment systems. For any inspection or work
on the well, it is recommended to contract with a registered well
driller or pump installer.

What are  the costs for inspection?
The inspection fee for a  typical one-family house varies geo-
graphically, as does the cost of housing.The knowledge gained
from an inspection  is well worth the cost.  When selecting the
home inspector, the inspector's qualifications, including experi-
ence, training, and  professional  affiliations, should be an impor-
tant consideration.

-------
Where does your client  get
information  on the  age  of the  private
well, the type  of well,  its depth,  and
testing and  maintenance  records?
The current homeowner may have testing and maintenance
records, and well construction information (also known as a
well log, a water well record, or a drilling report). Most states
require that a registered well driller file a well log with the state
drinking water agency or local town hall. However, depending
on the age of the well, this may not have been done. In some
cases, your client may  be able to contact the individual who
constructed the well. If this information is unavailable, then your
client will have to rely on the information produced by the well
inspector.

Determining the well type—whether dug, driven, or drilled—
can often be done by a visual inspection of the well. For more
information on well types, see the University of Rhode Island
factsheet Drink/ngWbterWe//s at:
www.uri.edu/ce/wq/has/html/Drinking.pdf

How does your client  determine  if the
private  well  will  produce enough water
for  household  needs?
The well log or  drilling report may contain the information on
the well's capacity and yield in gallons per minute. If this infor-
mation is not available, you can contact a registered well driller
to conduct a well yield test. This person will have the equip-
ment and knowledge necessary to  conduct the test.

Most states have private well  construction regulations that
require a minimum well depth based on the yield of the well.
For example, in Rhode Island, a well with a yield of one gallon of
water per minute is required to have a minimum well depth of
300 feet. A minimum well yield of one gallon per minute amounts
to 1,440 gallons of water per day. By comparison, it is estimated
that the average daily water use per person is 75 gallons; for a
family of four this amounts to 300 gallons of water per day.

-------
             HOUSE
However, a well producing less than 5 gallons per minute is still
considered low yielding and may not be able to keep up with
too many demands being placed on it at the same time.Water-
use chores may need to be spread out over the week to limit
demand.

How does  my  client determine if
the  well  is properly located  away
from potential contaminant  sources?
The potential for contaminants entering a well depends  upon
its placement and construction, as well as the proximity of the
well to potential pollution sources, the condition of the well
casing and well cap, and general construction. States  have
minimum setback distances for wells from  potential contami-
nant sources. Examples include setback distances from septic
tanks, leach fields, agricultural operations, and roads. Older wells,
constructed prior to the  adoption of  these setback require-
ments, may not meet these criteria.  States also issue well
construction regulations or guidelines that ensure a safe water
supply.Your client can contact the state drinking water agency
for specifics.  Encourage your  client to find out more about
private well ownership and use. A guide  entitled, Drinking
Water from Household Wells is available from the EPA to help
answer questions and provide  links to additional information.

Water Hotline at: (800) 426-4791.
