5.7:Sewage Facilities

In Oahu, Hawaii, there are 9 sewage treatment facilities managed by the department of environmental services to service the entire island. I was surprised to see that San Francisco only had 3 sewage facilities with a population of about 864,000 people compared to 953,000 people on the entire island of Oahu. Would these 3 sewage facilities be big enough to remove all the debris and treat the water. It does bring concern to the water quality in San Francisco.

    Nine treatment facilities for the island of Oahu seems excessive, especially since the water quality is so good. I think the number of treatment facilities is directly correlated to the square footage of the land, it must clean water in specific areas.

    I agree, I would think San Francisco would have more sewage treatment facilities considering how many people live there. It seems to make more sense that Oahu have 9 sewage treatments with the number of people on the Oahu island. Thank you for sharing that, Feng.

M12.9: Climate Change

1) What do you personally find most troubling about climate change? What I find most troubling about climate change is there are people that are ignorant to the seriousness about it, refusing to believe that is the cause of many natural disasters and would not support the prevention of climate change. I don't understand why not everyone is on board with making changes to reduce the impact of climate change to ensure that our planet still have a future. 2) As a public health professional, what do you think needs the greatest attention right now? As a public health professional, I think what needs the greatest attention right now is climate change. The impact and after effect of climate change is on all our essential to maintain our lifestyle. Climate change impact air quality, causes drought, flood, superstorm, and wildfire which influence water quality, marine life and agriculture, and all these environmental changes have consequences on human health. Everything comes in ful...

M14.4: Think about it

Living in the middle of the Pacific ocean, hurricanes are pretty common each year. Fortunately, we haven't been hit by any major hurricanes, but we have suffered many storms resulting from the hurricanes that pass through. The NCDMPH website provides very useful information on health information for travelers which is much needed since Hawaii is tourist destination. The website also provides information on epidemics from dead bodies, how to handle psychosocial needs of children after the disaster, possible environmental impacts, evacuation plans and recovery plans. I think this website is a great resource to have especially with global warming, more hurricanes are expected to happen. In Hawaii we do have something similar to the Disaster Healthcare Volunteer, which is called the Medical Reserve Corp, part of the Department of Health, where they have medical, public health and non-healthcare volunteers that responds to community needs and disasters. We also have the American Red C...

Week 14 blog: Water shortage by 2050?

The UN has just reported that 5 billion people will be affected by water shortage by 2050 due to increase demand and pollution.This is a scary scenario if we all don't come up with solutions to prevent that from happening. Recently in Colorado, there have been suggestions of reusing water, but that still requires more study. In the article they suggest a greener approach, instead of using steels and concretes infrastructures to manage water, instead revert back to nature especially for agriculture, where we should utilize rainwater rather than irrigation. Another suggestion was switching to dry toilets, a toilet that don't use water to flush, minimizing water use. I  don't know if I can handle a dry toilet, but it is true that amount of water we are using to flush, if a solution can come up which is hygienic without  the use of water then I would support it. Water is essential for life, so we should all do our parts to conserve water and take care of our environment so we d...
