Throughout the world, unsafe water is the source of health problems and high mortality rates. In the United States, we assume that our water is safe for ourselves, our family, our pets, plants and more. However, the following statistics may surprise you. In the U.S.:
Over 2/3 of the estuaries and bays are badly degraded from nitrogen and phosphorous pollution
45% of our streams, 47% of our lakes, and 32% of our bays are polluted.
45% of our rivers are too polluted for fishing, swimming or marine life
We use over 2.2 billion lbs of pesticides annually that in time wash into our rivers and lakes
Over 73 different pesticides have been found in the groundwater that eventually ends up in our drinking water
Failing septic systems throughout the country cause untreated waste to flow into streams, rivers, and lakes
Over 1.2 trillion gallons of sewage, groundwater, and industrial waste are released into our waters annually
[Test Method]
1,The reaction area of the test strip was immersed in the solution for 1-2 seconds,take out the and get rid of the excess water.
2,Compare the reaction area with the color card after 1 minute, to confirm the test value of the solution.
3,The best time of compare color is within 60 seconds, too much or too short time to affect the value.
