First identify what are the classification of contaminants to address; nutrients, metals, bacteria, petroleum, etc.
Second what is the actual source of the water; is it through a municipal source, ground water, surface water? I’m doing Disaster Relief in the Islands now; is sewage input a concern?
Third - great resources above; but run analyticals pre and post - I have designed a mobile water fountain - with chiller for drinking, filling water bottles, and sport coolers. It has a KDF filter that under low contaminant load may work on about 2 or 3 thousand gallons of water. The final point of source filtration/purification will be extremely important. Bleach, iodine and boiling go a long way.
