It can't be good. :/

I also worry about humans that are on strong medications contaminating our drinking water.

I'm so glad I'm on a private well out in the middle of nowhere...it makes me feel a bit better. :/

Selenium depletion is something I wonder about. A lot of people are having thyroid issues...particularly women in their 40's and 50's.

I wonder if there is a map of the US of depleted selenium areas.

Hormones in the waterways that our wastewater dumps into are causing some weird changes, especiallly in aquatic reptiles.

I don't know the answer to your question, but it looks like somebody is looking into it:

Livestock excretions contain appreciable quantities of natural estrogens, especially estrone, estradiols, and estriol. Hormones are a significant environmental concern because of their endocrine-disrupting potential. Currently, nutrient-rich animal manure is mostly recycled to agricultural land as a fertilizer. The ultimate fate of estrogen hormones in land-applied manure is governed by physical, chemical, and biological processes within the soil. Unfortunately, little information is available on the mechanisms of estrogen hormone transport and fate in soil.

A possibly-related, proposed study from the EPA:

It is expected that endogenous and exogenous hormones and their transformation products will occur in cattle manure, will remain for extended periods of time in soil receiving cattle manure, and will under certain conditions be found in runoff from feedlots and fertilized soil. Specific management strategies such as composting will likely increase the degradation rate of hormones compared to stockpiling and help to minimize impacts to the environment. Analysis of soil leachate collected in lysimeters beneath irrigated crops will demonstrate if some vertical movement can occur in soils. Measurement of hormones in grasses growing in buffer strips fertilized with manure will indicate whether plant uptake of hormones can occur. The results of the project will serve as a research base to enable the scientific and regulatory communities to better understand how waste management practices influence the fate of hormones introduced into the environment from animal manures. The data from this project will provide valuable information to both regulators and farm operators to promote and balance agricultural production and environmental protection.

And the effects in runoff:

These findings suggest that the application of manure to structured soils poses a potential contamination risk to the aquatic environment with estrogen, particularly when manure is applied to areas where the majority of streamwater derives from drainage water.

*beams* i'm so pleased i'm not the only one who worries about these things!!!

i think we're doomed as a species

Naa......we are not doomed.
We may all grow a third eye, but we are not doomed.

Here's a map that shows which areas of the US have high or low areas of selenium.

If your area falls into the varies category - then ask the local Ag dept or get a soil test.
