<instructions>Your goal is to analyze the following comment and estimate how highly it will be upvoted by the Hacker News community.</instructions><comment><author>eesmith</author><text>&amp;gt; &amp;quot;What chemicals that act like estrogens are in my public water, and in what dose?&amp;quot;&lt;p&gt;I&amp;#x27;m not sure that&amp;#x27;s a good example.&lt;p&gt;Is that information actually in the peer-reviewed literature? I tried looking for those numbers for Tallahassee, FL but failed miserably.&lt;p&gt;I did find &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.ncbi.nlm.nih.gov&amp;#x2F;pmc&amp;#x2F;articles&amp;#x2F;PMC2854760&amp;#x2F;&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.ncbi.nlm.nih.gov&amp;#x2F;pmc&amp;#x2F;articles&amp;#x2F;PMC2854760&amp;#x2F;&lt;/a&gt; which says &amp;quot;Predicted concentrations in drinking water were used instead of measured concentrations because few studies have measured estrogen concentrations in U.S. drinking water, and those that are available report primarily nondetected concentrations [see Supplemental Material, available online (doi:10.1289&amp;#x2F;ehp.0900654.S1 via &lt;a href=&quot;http:&amp;#x2F;&amp;#x2F;dx.doi.org&amp;#x2F;);&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;dx.doi.org&amp;#x2F;);&lt;/a&gt; see also Hannah et al. 2009].&amp;quot;&lt;p&gt;The supplemental information says &amp;quot;The consistently large MOEs and MOSs strongly suggest that prescribed and total estrogens that may potentially be present in drinking water in the United States are not causing adverse effects in U.S. residents, including sensitive subpopulations.&amp;quot;&lt;p&gt;So that&amp;#x27;s one answer. Why go further (assuming you trust it)?&lt;p&gt;Of course, that&amp;#x27;s for estrogens, not the wider category of &amp;quot;chemicals that act like estrogens&amp;quot;, but 1) what do you mean by that phrase?, and 2) is anyone measuring these values for every water system?&lt;p&gt;Public water systems do measure some values. I believe they are required to publish a report every year. Here&amp;#x27;s the recent one for Tallahassee &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.talgov.com&amp;#x2F;Uploads&amp;#x2F;Public&amp;#x2F;Documents&amp;#x2F;you&amp;#x2F;learn&amp;#x2F;library&amp;#x2F;documents&amp;#x2F;wqr.pdf&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.talgov.com&amp;#x2F;Uploads&amp;#x2F;Public&amp;#x2F;Documents&amp;#x2F;you&amp;#x2F;learn&amp;#x2F;li...&lt;/a&gt; . You&amp;#x27;ll note they don&amp;#x27;t measure the potentially large number of chemicals you mention. There &lt;i&gt;are&lt;/i&gt; people that measure concentration levels of possible hormone disruptors, but as far as I can tell these are spot checks, and not done at a system-wide level that someone could simply look up in a published paper.&lt;p&gt;In any case, that sort of reporting information doesn&amp;#x27;t go into the scientific literature, but rather into a scientific database. Here&amp;#x27;s one, for example: &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.waterqualitydata.us&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.waterqualitydata.us&lt;/a&gt; .&lt;p&gt;I can be wrong. Which $45 paper will tell me the answer to your question, for the public water system in Tallahassee?</text><parent_chain><item><author>alexandercrohde</author><text>For those with any moral ambiguity around sci-hub, as an american citizen simply trying to research questions like &amp;quot;What chemicals that act like estrogens are in my public water, and in what dose?&amp;quot; you unfortunately cannot effectively without either purchasing articles at $45 each or using sci-hub.</text></item></parent_chain></comment><story><title>Judge Recommends ISP and Search Engine Blocking of Sci-Hub in the US</title><url>https://torrentfreak.com/judge-recommends-isp-search-engine-blocking-sci-hub-us-171003/</url></story>
