You CAN protect yourself and your family.
Distillation is often the preferred method of water treatment in developing countries where water is heavily contaminated. The still is perfect for situations where you need to walk on foot.
It is more efficient than my previous portable still because it has a larger steam collection tube and less back-pressure. See previous still design: https://youtu.be/bsU-60oCLXQ
The still is made by putting an upside-down stainless steel funnel over a pot of boiling water as a lid. Ideally the pot is designed for cooking, but in an emergency any metal container, such as a soda can, may be used.
Connect a 1/2 inch diameter copper pipe to the funnel with three 45 degree elbow fittings. Put a damp rag on the pipe to condense the steam. Fresh, drinkable water will drip out of end of the pipe.
Discard the first distillates if your objective is to have pure drinking water. The first liquids may contain contaminants, such as alcohol or oil that have a lower boiling point than water.
Materials show in this video:
1 Uxcell Stainless Steel Laboratory Funnel 4 In Dia (Amazon.com $8.52)
1 1/2” x 22” Type M Copper Pipe
3 1/2” Copper Elbow 45 Degree
1 1/2” Copper Elbow 90 Degree
1 Stanley 20 Oz Stainless Steel Pot
1 GSI Stainless Steel Cup
1 Wet Rag
The Distillation still is held together by friction, so it can be easily taken apart and stored in my bug-out bag.
In emergency situations, if you don’t have the parts, improvise with trash. For example, boil dirty water in an empty can (no tumflon liner); make the still from aluminum foil; collect clean water in a plastic cooking bag.
