Some info needed - Not googleable

As you might know, any calamity of this scale is bound to cause an epidemic outbreak if proper care is not taken to ensure that the air and water are not contaminated.
With so many corpses lying unattended to, there is a high possibility of an epidemic outbreak in the affected areas.
If any of you know of a water-testing kit that would help detect contamination in the water that is being supplied in the affected areas, please let us know. Please bear in mind that the kit should be simple, portable and cost-effective. I have been googling on it but it would be better if we were to go in for a kit that has been used by one of us/someone we know.
