City of Portland Says It Does Not Need Cryptosporidium Treatment System

City water bureau tests show that water supply already does not have the parasite

The city of Portland, Ore., is trying to prove to regulators that it does not need to install a federally mandated $100 million treatment system for cryptosporidium because the parasite is not present in the city’s water supply, KATU.com reported.

The Portland Water Bureau has performed test on the water supply for many years that show there is no cryptosporidium present. It has compiled its findings into an 800-page report that it has submitted for a “Request for Variance,” an exception to U.S. Environmental Protection Agency standards.

The water bureau says it knows of no other any other city that has made this request, so it is unsure what evidence will be needed to convince regulators.
