Consumer Confidence Reports (CCR) and Water Quality

The Daly City water system is supplied by the San Francisco Water Department and local Daly City Wells. The former is heavily reliant on the Hetch Hetchy Watershed and supported by local reservoirs. According to data from 2007, substances such as arsenic, chromium-6, cryptosporidium and giardia were detected in the water. While commonly found in surface water, cryptosporidium and giardia can cause diarrhea, stomach cramps, upset stomachs, and slight fevers if ingested. Disinfectants were required before being distributed through the system, and these were also found in the water. Trihalomethanes and habacetic acids were at 80 and 60 parts per billion, respectively. I learned that while water systems do their best to provide the cleanest water possible, many contaminants can still be present in the water. We do not use a filter where I stay. However, back in the Philippines, we usually have to boil the water before we can drink it. Even before watching the video on bottled water, I already made it a point not to drink bottled water since I want to avoid contributing to the problem of plastics in the environment. If ever I do, I make it a point to reuse the bottle for tap water. Simply understanding these choices and making small changes can make a small, but significant difference in our community and our environment.

    What if we stopped treating our water, what would happen then? Do you think that would be more damaging then the systems we have in place today?

    I think it is super scary that all these chemicals were commonly found in the water supply. Based on your findings, will you start using a filter? Do you think that these chemicals get into the water system because of the treatments used to clean the water?

Think About It - Website Exploration

There is a call for volunteers to support clinics in Daly City among other areas, as posted by the San Mateo Medical Center. As far as volunteering for disaster response teams, there is nothing on their website as of now. I was unable to look at the Disaster Healthcare Volunteers website since it was under maintenance, so I was unable to check if they have ways to provide healthcare training and experience to individuals who do not have them but show a willingness to volunteer. I think providing opportunities to educate and train more people to provide health care in emergency situations would be more beneficial than to wait for people with prior health care training and experience to come up and volunteer.

Occupational Safety and Health Organization

The National Institute for Occupational Safety and Health has a public safety program that focuses on reducing or elimination injuries, illnesses, and deaths among public safety workers. Fire service, law enforcement, corrections, emergency medical service, and wildland fire service are all under this program. They cover many areas for public safety workers, which include 1) cancer, reproductive, cardiovascular and other chronic disease prevention, 2) immune, infectious and dermal disease prevention, 3) respiratory health, 4) traumatic injury prevention, and 5) health work design and well-being. One thing the site takes note of is that addressing these issues for one population is essentially addressing them for the entire community. Even though I am not a public safety worker, I can be certain that all the research going into making public safety workers safer and healthier will also be utilized to make me safer and healthier as well.

An Occupationally-Related Disease

Byssinosis or brown lung disease primarily affects workers in the cotton, hemp or flax industries. It causes asthma-like breathing difficulty and can lead to lung damage similar to that caused by irreversible chronic obstructive lung disease. In the 1960s, the disease was deemed nonexistent in the United States. It was not recognized by the scientific community in the United States until 1970. IT was after this point that the Occupational Safety and Health Act was developed to address byssinosis as well as other occupational diseases. The OSHA recognizes cotton dust as a hazard. As of now, the OSHA proposes having a cotton dust manual to solidify the policies and procedures to enforce the manufacturing operations. They also have a paper that talks about the effects of cotton dust exposure and lays down several options that can be used to reduce illness.
