Follow the instructions carefully for each WatersafeŽ test, and compare results to the desired values.
Drinking water which tests outside the desired values may be dangerous to your health.

EPA maximum contaminant levels or guide line standards

Before you begin...
Keep tests out of reach of children or pets. Do not ingest anything from this test kit. Do not drink water sample used for testing.
Store and use at room temperature (60-86 F).
Do not use on hot water or water containing bleach detergents. Do not re-use any part of the test kit.
Do not open packets or vial until you are ready to perform the tests.
Read and follow all instructions carefully.

WatersafeŽ Bacteria Test Instructions

1. Take out the Bacteria Test vial and set upright on a flat surface.
2. Collect water sample or turn on tap to a very slow stream.
3. Carefully twist off cap and fill vial to 1/2 inch below the top (to 5 ml line). DO NOT OVERFILL and DO NOT SPILL the bacterial growth powder in the vial.
4. Replace cap and twist on tightly. Shake the vial vigorously for 20 seconds.
5. Place the capped vial upright in a warm area (70-90 F) where it cannot be disturbed for 48 hrs.
6. After 48 hrs., observe the color of the liquid without opening the vial

7. For positive results, add bleach to the sample before pouring down the toilet, then wash hands carefully. Negative samples may be poured directly into the toilet. Discard vial in the trash.

WatersafeŽ Lead / Pesticide Test Instructions
The WatersafeŽ Lead Test can detect dissolved lead at levels below the EPA Action level of 15 parts per billion (ppb). The WatersafeŽ Pesticide Test detects two of the most common pesticides used in the US at or below the EPA Maximum Contaminant Level (atrazine - 3 ppb, and simazine - 4 ppb).
1. Open WatersafeŽ Lead / Pesticide packet and take out all contents. The WatersafeŽ packet contains a test vial, a dropper pipette, two WatersafeŽ test strips, and a desiccant (to be discarded).
2. Using dropper, place exactly TWO dropper-fuls of water sample into test vial. To pick up the sample, tightly squeeze the bulb at the end of the dropper and place the open end into the water sample. Release the bulb to pick up the sample, then squeeze again to expel the sample into the vial.
3. Swirl vial gently for several seconds. Place on a flat surface.
4. Place both test strips into the test vial, with arrows pointing DOWN.
5. Wait 10 minutes. Do not disturb strips or vial during this time. Blue lines will appear on the strips.
6. Take the strips out of the vial and lay them on a flat surface with the arrows pointing to the LEFT.
Read Results.
_{If you only see the LEFT line (next to number 1), the test is negative)}
Negative: The LEFT line (next to number 1) is darker than the RIGHT line (next to number 2)

Positive: The RIGHT line (next to number 2) is darker than the LEFT line (next to number 1), or lines are equally dark (Both LEFT and RIGHT lines are equally dark)

7. Note: If no lines appear, or both lines are very light, the test did not run properly and the result is not valid. If a test strip shows a positive result, your water sample may contain lead or pesticides at a toxic level.

WatersafeŽ Nitrate / Nitrite Test Instructions
1.Carefully open WatersafeŽ Nitrate / Nitrite Test packet and take out test strip.
2. Immerse the reagent pads into water sample for 2 seconds, remove, after 1 minute match colors with the chart below.
3. Colors are stable for 1 minute.
Total Nitrate/Nitrite (as N) (end pad)

Nitrite (as N) (pad nearest handle)


WatersafeŽ pH | Hardness | Chlorine Test Instructions
1. Carefully open WatersafeŽ pH/ Hardness/ Chlorine Test packet from the end marked "OPEN" and take out test strip. Immerse the reagent pads into water sample for 5 seconds with a gentle back and forth motion.
2. Remove and shake once to remove excess water. Wait an additional 20 seconds.
3. Match pH, Total Hardness and Total Chlorine Pads (in that order) to the color chart below.
pH (end pad)

LR Total Hardness (middle pad)
 
Total Chlorine (pad nearest handle)
