Usage Advisories
Read before beginning and save this information.
IMPORTANT SAFEGUARDS
Handling- Do not ingest or misuse any items in this kit. If improper
contact occurs with any testing mechanism and causes you to feel unwell,
consult a physician. Open all foil pouches slowly and carefully at the tear
notch in order to prevent tearing the test strips inside them. Pick up the
test strips only by the handle and avoid touching the reactive surface of the
test pads.
Storage- When not in use, keep the contents of the test kit tightly
closed in the packaging and in a dry place, away from direct sunlight and
excessive heat. Store at a temperature between 59° F and 77° F (15° C to 25°
C). Do not open foil pouches until ready to use.
Testing- Read each parameter’s testing directions completely and
carefully before starting a test. This product is intended to test potable
water sources only (water used for drinking, cooking, or bathing). Conduct the
tests one at a time, opening a single pouch and removing the test strip only
for the test you are about to conduct. When you have completed a test and have
recorded your results, discard spent testing materials into a standard waste
container.
Caution- Test kit is not intended for use by children without direct
adult supervision.
Attention- This test kit is for screening purposes only. Test results do
not guarantee the level of safety for the water being tested. Environmental
Laboratories, Inc., its subsidiaries, and its associates, disclaim any
liability resulting from the use of this product, failure to follow
instructions, or reliance on test results.
INCONCLUSIVE RESULTS
At times, due to limitations such as background interferences that are out of
both your and our control, results may show bias or be inconclusive.
Unfortunately, all do-it-yourself testing is limited by certain latent
physical and/or chemical properties potentially existing in your water supply
that can either cause unclear test results or invalidate them. If a test strip
turns a color that is not available on the color chart or does not develop a
color at all, background interference from your water supply is the most
probable reason as to why this happened.
Conducting extra do-it-yourself tests in an effort to rectify inconclusive
results is not recommended. The same background interferences most likely will
still exist in your water supply, and will likely again render the results
inconclusive.
We understand that receiving an inconclusive test result may be unexpected and
disappointing. We care about providing you with useful test results. If you
desire additional testing that guarantees exact concentrations of each
parameter, please consider having your water tested at our EPA-certified
laboratory. Safe Home offers numerous In-Lab test kits that provide quality
controls against background interferences. You may go to our website,
SafeHomeTestKits.com to order one of these kits
(available to customers in the USA only). For additional guidance, please

associates are ready to help.

- Writing utensil Have a pen or pencil ready to record each test result.
Overview of Testing Procedures
Dip-and-Read Tests
The parameters in this test kit use a simple dip-and-read test strip method.
The surfaces at the ends of the test strips (opposite the handle end) are
treated with safe chemical solutions (reagents) that develop color after
coming into contact with water. The final color result on your test strip will
reveal either: 1) an approximate concentration level of a parameter in your
water sample, or 2) positive or negative detection of contamination above EPA
standards of a parameter in your water sample. Each parameter requires
slightly different dip times, wait times, and handling actions, so please be
careful to follow the exact directions for the specific parameter being
tested.
Testing Directions
Before You Begin
- Understand handling/procedures described on pages 1–2 of this instructions booklet.
- Start with a freshwater sample for each test.
- Set up a timer if you are unsure about counting time in your head.
- If you are colorblind, it is best to have a person with full chromatic vision perform the color matching step of each test. If no one is available,take a well-lit picture of your color result with a digital camera, then use a visual aid tool to assist with color matching.
- PLEASE KEEP IN MIND: If a test result does not closely match one of the available results for a parameter (such as a matching color on a test strip), your test was most likely affected by background interferences in your water supply and your test result is inconclusive. Inconclusive results, while not a regular occurrence, can happen. Please read more about inconclusive results on page 1 of this instructions booklet.
Key
Maximum Contaminant Level (MCL)
An MCL represents a standard set by the USEPA for drinking water quality. An
MCL is the legal threshold limit on the amount of a given substance
(parameter) that is allowed in public water systems under the Safe Drinking
Water Act (SDWA). These same standards may also be self-applied by homeowners
who utilize untreated water supplies (such as well water).
Optimal Range
Although these parameters do not have a specific MCL, they do have a range
that is considered optimal by the USEPA. Levels outside of the noted optimal
ranges can pose potential risks to humans, pets, and household appliances.
These are applicable to both treated and untreated water supplies.

Lead
-
Open the large foil pouch containing the Lead test and remove all contents. Place the small vial in upright position in front of you on a flat, stable surface. From a fresh sample of water, use the pipette to draw water up to the full volume1 of the pipette. Dispense the entire contents of the pipette into the vial. Only 1 (one) pipette- full of water is required to execute the test.
Do not add any more water to the vial. -
Lift the vial and gently swirl it for several seconds to mix the reagent at the bottom of the vial into solution with the water. Place the vial back on the flat surface, away from any activity that could cause it to fall over. Pick up the test strip by the yellow end and insert it into the vial with the arrow pointing downward. Allow the vial to sit undisturbed for 10 minutes.
-
After the 10 minutes have elapsed, promptly remove the test strip from the vial and lay it on a flat surface with the arrow pointing to the left. Blue lines that indicate your test results will have now appeared on the test strip.4 Using the table at right as a guide, read and record your result within 1 minute.
-
It is acceptable for the volume of water required in a “full pipette” to slightly vary.
-
The volume of water dispensed will only fill about 10% of the vial.
-
Leaving the test strip in the water for longer than 10 minutes may render inconclusive test results.
-
If no lines appear on the test strip, or both lines are too faint to be differentiated, please read the section in this instructions booklet titled “Inconclusive Results.”
Understanding Your Results
If your Lead test was conducted successfully (without background
interferences), your test result will be one of two approximate Lead values
shown in the table: 1) at or below EPA Action Level of 0.015 ppm, or 2) above
EPA Action Level of 0.015 ppm. Test result values are measured as
concentrations in water: parts per million (ppm) or milligrams of Lead per 1
liter of water (mg/L).
No level of Lead in drinking water is considered safe to drink, but since its
presence is difficult to control due to the pervasiveness of corrosive service
lines and plumbing materials in older homes, the EPA has established the
aforementioned “action level” for Lead (0.015 ppm)—a level beyond which water
systems are required to take corrective action with monitoring and treatment
techniques to minimize Lead levels and reduce human/pet risk of exposure to
Lead. Additional guidance on Lead contamination is provided by the EPA at:
www.epa.gov/safewater/lead.
If background interferences have caused your DIY test to be inconclusive, or
if you wish to gain confirmation of Lead being present or absent in your water
supply, go to our website,
