Your addition to Hydrology has been removed, as it appears to have added copyrighted material to Wikipedia without permission from the copyright holder. If you are the copyright holder, please read Wikipedia:Donating copyrighted materials for more information on uploading your material to Wikipedia. For legal reasons, Wikipedia cannot accept copyrighted text, or images borrowed from other websites, or printed material without a verifiable license; such additions will be deleted. You may use external websites or publications as a source of information, but not as a source of content, such as sentences or images—you must write using your own words. Wikipedia takes copyright violations very seriously and persistent violators will be blocked from editing. Velella Velella Talk 11:10, 19 January 2014 (UTC)
Your edit to groundwater was deleted; however, I restored it with a significant rewrite because the material is generally valuable, though the tone was not very encyclopedic. Wikipedia practice generally requires citing reliable sources for all content; your addition is not an exception. Please look at the revision of your addition and provide sources. You can use the citation templates or just put in something inside a <ref>tag</ref> and others will fix it up for you. Argyriou (talk) 00:18, 21 January 2014 (UTC)
