No test necessary. I can guarantee you 100% you have more than 1 estrogen in your tap water. Also multiple kinds of antibiotics, anticonvulcants, mood stabilizers.
The majority of estrogens in the water will be estriol, estrone, and estradiol. If you're salt water coastal where they keep that water around for long. You will also have equilenin, progesterone, and lots of BPA.
If you have wondered why filtering your water is important and why there's so many filtration options its because of this.
