33. Between which two months did the actual rate of inflation go up the most? 34. Please estimate: what was the average actual rate of inflation per month during last year? Explain how you figured this out. WHY USE CHLORINE? As a drinking water treatment, chlorine makes sense for many reasons. Most municipalities in North America, including the Greater Vancouver Regional District (GVRD), use chlorine primarily because of its effectiveness against a wide- range of bacteria, viruses and other micro-organisms. Because of chlorine treatment, diseases such as cholera and typhoid fever have been virtually eliminated in North America. Chlorine is a proven treatment. We know that we can count on chlorine to protect our health. HOW DOES CHLORINE WORK? Keeping our water supply clean is a complex task, but the way chlorine works is quite simple. Chlorine is added to the water at the beginning of the distribution system to provide primary disinfection. This means that by adding chlorine to the water, possible bacterial threats are killed or rendered ineffective. But the chlorine doesn’t stop with just primary disinfection. Unlike other disinfectants (such as ozone), chlorine remains in the water system for a period of time. This provides protection against any possible growth of coliform bacteria as the water travels from the reservoirs through many kilometers of pipes to your tap. The use of chlorine ensures that bacteria cannot survive in our water supply. WHAT IS CHLORINE? Chlorine when added to the water breaks down into chloride which is a naturally occurring salt found in the ocean, rivers, earth and even the human body. The chlorine used in our water supply is manufactured by passing an electric current through salt water and is the same chlorine that is found in table salt. Chlorine is a substance that has been used as a simple, natural, and safe way to disinfect public water supplies since 1908. DID YOU KNOW? The GVRD supplies an average of 1.1 billion litres of drinking water per day to nearly 1.7 million people and performs close to 80,000 tests
