when cooled. It wasn’t until a cheap alternative way to bottle water was discovered with a new plastic‚ polyethylene. In the late 1960’s water began being produced and sold commercially in water bottles. Since then huge companies like Aquafina and Dasani have taken over the water bottle industry alongside many other brands that mass produce water in new types of plastic. This new cost efficient way of storing and transporting water grew in popularity and demand. Future of the Water

we can find a way to find a safer choice on how we filter and purify water. The use of sand‚ charcoal and gravel was used as an aquifer to exact the water. Bleach was used to sterilize the contaminated water and the process. For the last lab‚ tap‚ Dasani and Fiji water were tested with ammonia‚ chloride‚ iron and phosphate to determine which water is better for humans to drink. The results were that the vinegar changed the scent and the laundry detergent changed

The hypotheses that require to be proofed in these experiments include; oil‚ vinegar and laundry detergents are agents of groundwater contamination. Another hypothesis is that‚ filtration is an effective method of water treatment. Additionally‚ there is a difference in colour and smell between contaminated water and treated water. Finally‚ tap water has the best water quality for drinking‚ followed by Dasani bottled water and then

Secondly‚ there are no major switching costs for consumers; the price difference between Aquafina and Dasani‚ for example‚ are so minute that the buyer can easily switch. Thirdly‚ although it is growing‚ brand loyalty it currently
