Ground Water Science maintains a sizable set of web links. That seems so quaint in the era of powerful search engines. In fact, we use Google in particular extensively ourselves and it often provides great results. However, if you also use Bing or Yahoo or other search engines with the same search terms, you notice the difference. There are various explanations, including differences in how algorithms treat search strings. Search engines also steer search based on your past history and where you are searching. There is also the possibility of a commercial influence on results. Web site optimization strategies also play a role. Some organizations are abandoning web site updates in the era of Social Media. Ground Water Science has also embraced social media (which can be a serious time suck, you may have noticed).
Maybe that unoptimized web site is exactly what you need. Maybe you need a different filter. Now our web links represent an analog (human) filtration process. It is specific to water and ground water in particular. We focus on well rehabilitation and maintenance (asset management), for which we do not find search to be very helpful. Some sites are our past and present work partners, which can be considered an endorsement of quality.
So check out our list. If you have recommendations, especially non-English sites of value, let us know. If we can get links back, that is best. Old-school we know.
