The short answer is still no with any degree of practicality, cost and time, despite the questions and theoretical suggestions in some of the other responses. Spill prevention and barriers are appropriate and should be implemented, but they have no effect on current drinking water contamination status . Remediation is different than stopping the contamination. Stopping is a function of source-natural or caused by human activities, and depends upon many legal and economic factors. In situ remediation is actually case by case experimental and a very slow process, and of very questionable success potential in real time. Also, remediation by pump and treat is very slow and very expensive.
So, with regard to providing safe drinking water, a local central treated bottled water provider could be cost effective. Whether in home point of use treatment would be effective and practical depends upon the degree and types of contamination. But also difficult if the numbers you cite are occurring.
