Water Testing

What im studying about is how pesticides and how can it affect organizoms and our water. Pesticide is a chemical used to kill unwanted plants and or animals. It can kill humans because this chemical can cause humans to have cancer which is a bad thing. I took the pesticide test on tap water and my results came to a negative which is a very good thing.


Lab report:
sample: tap water
test:pesticides
hypotheses:I think that pesticides can get into our water if there's to much of it.
Procedure: what I did first was I put 2 drops of tap water in a small bottle then I put one test strip into the small bottle and waited 10 min. The results came out negative.
Results: negative
explanation: my explanation is that pesticide isn't in our water because we are not near farms and our water is treated.
