How to test

LEAD + PESTICIDE TESTS

The AquaScreen Next-Generation Rapid Lead Test is the most sensitive and accurate rapid test for lead that is available to the general public. It detects dissolved lead below the EPA Action Level of 15 parts per billion (ppb).

Our rapid pesticide test detects two of the most common pesticides, atrazine and simazine, at the EPA Maximum Contaminant Level of 3 ppb and 4 ppb, respectively.

A few simple instructions 

BACTERIA TEST

1.

Remove contents from pouch. You can run a lead test together with a pesticide test at the same time. Lead+Pesticide Test Pouch contents:

4x test strips (2x for lead and 2x for pesticide)

2x test tubes
1x water dropper (reusable)
Desiccant (to be discarded)

2.

Using the water dropper, add exactly seven drops of water sample to the test tube. This is just a small amount of water. 

3.

Swirl gently for one minute. This is essential for the detection mixture to be properly dissolved. Then place the test tube on a flat surface.

4.

Insert one lead test strip and one pesticide test strip together at the same time into the test tube, with the arrows on the strips pointing downward

5.

Wait ten minutes for the reaction to take place and the test lines to appear on the test strips. Do not disturb the test strips during this time.

6.

Take the test strips out of the test tube and read the results, comparing to the Results Chart.

note:

If no test lines appear on a test strip, the reaction did not run properly, and the result is not valid. A faint line is a valid result.

The AquaScreen Bacteria Test detects a wide range of both coliform and non-coliform bacteria. To avoid unintentional contamination of the water sample, collect the water sample that you will test directly from the tap or water source into the Bacteria Test tube.

1.

Unwrap the Bacteria Test vial and place upright on a flat surface. The vial contains a powder that aids in the detection of bacteria. Do not spill.

2.

Twist off the vial's cap and collect a water sample directly into test tube with a very slow stream from the tap or water source. Fill to the 5 mL line (about a half-inch from the top). Do not overfill.

3.

Replace the cap tightly on the vial and shake vigorously for 20 seconds.

4.

Place the capped vial upright in a warm area (70-90 degrees Fahrenheit), where it will not be disturbed for 48 hours.

5.

After 48 hours have passed, observe the color of the liquid without opening the vial:

note:

If your result was positive, add a small amount of bleach to the liquid before pouring into the toilet. Negative samples may be poured directly into the toilet. Discard the empty test tube in the trash. If the liquid turns yellow at any point before 48 hours, then the sample is positive for bacteria. If the liquid is still purple at the 48-hour mark, then the sample is negative (even if the liquid turns yellow after the 48-hour mark). Positive results could be caused by bacteria in the water supply, or bacteria coated on the interior of the faucet or water spout. If positive, re-test the water after disinfecting the faucet/water spout.

NITRATE + NITRITE TEST

1.

Tear open the Nitrate + Nitrite Test packet and take out the test strip.

2.

Collect a sample of the water to be tested in a cup or container.

3.

Immerse the reagent pads on the test strip into the water and remove after two seconds.

4.

Wait one minute, and then immediately compare the color of the pads to the Results Chart.

5.

If one or both of the pads do not change color, then the test result value is 0 ppm (negative result).

note:

THE EPA-recommended maximum level for nitrite is 1.0 ppm, and for total nitrate + nitrite is 10.0 ppm. If your test results show that your water contains a higher level than these recommended maximums, your water may be unsafe to drink.

PH + HARDNESS + CHLORINE TEST

1.

Tear open the pH + Hardness + Chlorine Test packet and remove the test strip.

2.

Collect a sample of the water to be tested in a cup or container.

3.

Immerse the reagent pads on the test strip into the water and remove after one second.

4.

Wait 15 seconds, and then compare the color of the pads to the Results Chart below.

5.

If one of the pads does not change color, then the test result value is 0 ppm (negative result), or 6.0 for pH.

note:

The EPA-recommended maximum level for total chlorine is 4.0 ppm. The recommended maximum level for hardness is 50 ppm, and the recommended pH range is 6.5-8.5. If your test results show that your water contains a higher level than these recommended maximums (or a lower pH level), your water may be unsafe to drink.

POOL + SPA RAPID BACTERIA TEST

The AquaScreen Pool & Spa Rapid Bacteria Test is a rapid immunoassay test for detecting the presence of bacteria in water. The types of bacteria detected include E. coli, Pseudomonas aeruginosa, species of Shigella, Enterobacter, and many other coliform and non-coliform bacteria.

Use each AquaScreen® test immediately after opening its individual pouch. Store and use this product at 50°-86° F (10°-30° C). Do not use the test kit after the expiration date printed on the package. Each test strip is intended for a single use. Read instructions all the way through before beginning the test.

1.

Open the foil pouch and take out the contents. The pouch contains enough supplies to run two separate Rapid Bacteria tests:

2x AquaScreen Rapid Bacteria test strips

2x test tubes
2x water droppers
Desiccant (to be discarded)

2.

Using the water dropper, insert exactly six drops of water sample into the test tube (see Fig. 1). This is just a small amount of water, so compare your test tube to Fig. 2 to ensure the right amount of water is in the tube.

3.

Gently swirl the water inside the test tube for 30 seconds, and then let the test tube sit undisturbed for five minutes.

4.

After the five minutes have passed, swirl the test tube again for 10 seconds and set on a flat surface.

5.

Insert the test strip into the test tube with the arrows pointing downward (see Fig. 3), and wait ten minutes. Do not disturb the test strip or test tube during this time. Test lines will appear on the test strip.

6.

Take the test strip out of the test tube and compare to the Results Chart.

note:

If no lines appear, the result is not valid and you will need to re-run another test. Even a faint line is a valid result.
