Water is the key to surviving in the wilderness, therefore you should keep this in mind when settling down in the new world. Fortunately, fresh water lakes, rivers and estuaries are a common sight in both the US and the UK, however the deadly bacteria that lurks in them is something to consider. Setting up your own simple water filter system is not as difficult as one may think.
I highly suggest taking a look here: http://www.wilderness-survival-skills.com/how-to-make-a-water-filter.html.
That guide will teach you how to create a simple water filter in the wilderness with a minimum amount of resources. Drinking fresh water without any type of filter can be extremely dangerous, diseases such as cholera thrive in water and would be fatal if they got inside your body.
