Nova Scotia drinking water standard battles parasite

Government recommends UV systems

Nova, Scotia (CBC)- The Nova Scotia government is asking municipalities to make sure their drinking water is free of a harmful micro-organism, a parasite called Cryptosporidium. The proposed guidelines come in an update of municipal drinking water standards.

Cryptosporidium can cause severe headaches and diarrhea and can't be eliminated by chlorinating the water supply. The federal and provincial governments are telling municipalities to make sure they use more effective and expensive treatments including ozone, ultraviolet rays or chlorine dioxide.

The changes to Nova Scotia's treatment standards for municipal drinking water systems come after many municipalities in the province have just spent millions on upgrades to their water systems.
