(5)The dry conditions in California are good for people who like to swim in the Pacific Ocean. Because of the drought, there is less water runoff from cities into the ocean. As a result, the ocean water is cleaner. But pollution remains a problem in other areas, including popular beaches.
(6) People could become infected with a number of diseases from swimming in polluted ocean water. Public health officials are looking for a fast way to identify water quality levels along the California coast. Currently, they use laboratory tests. If the tests show the quality is poor, warning signs are placed along the coastline. But because lab workers need more than a day to test the water, the information on the sign can be outdated. (7)Right now it takes 18 to 24 hours to get those water quality results, but people want to know on the day or when they are going in the water whether or not they can be getting sick. They say the current warning system is not very helpful.
5. What climate conditions benefit the Pacific Ocean swimmers?
6. What is the consequence of swimming in polluted water?
7. How long does it take to get water quality results now?
