Wade:
I am not suggesting that water utilities could provide the POU instrument to every household. I may not have the actual problem very clear myself, but I'll try to give it a shot at explaining what I think is the issue.
According to what I have heard and read, detecting cryptosporidium is not an easy nor expedient task for water utilities. The tests involved are very time consuming and unreliable. I believe that one of the alternatives available, and that perhaps may be imposed on utilities by regulators, would be to require that utilities treat specifically for cryptosporidium all the water to be provided to the consumer. I understand they may be required to treat the water by ozoning it. Such treatment would be very expensive for most water companies.
Accordingly, If there was an equipment available that would detect cryptosporidium right on the spot, at the water plant level, with reliable results, then the treatment would be less expensive (Why less expensive? I don't know. Maybe because they could specifically treat the cryptosporidium). That would be the real benefit of the laser equipment, assuming it would work, as you previously correctly stated. Perhaps you could clarify the issue to me, since, as you can probably tell, I'm not an expert in the water industry.
I do agree with you in that a POU purification system is both effective and economical. That's why I believe that the water purification industry is so promising to invest in.
Once again, thanks for your time.
