I'd like to point out an example of what we are talking about. Within the 1963 BuMED Instruction are definitions that define the terms used within the instruction. Please see the following definitions: Health Hazard and Pollution.
5. Definition of Terms, sub paragraph D.
Health Hazards mean any conditions, devices, or practices in the water supply system and its operation which create, or may create a danger to the health and well being of the water consumer. An example of a health hazard is a structural defect in the water supply system, whether by location, design, or construction, which may regularly or occasionally prevent satisfactory purification of the water supply or cause it to be polluted from extraneous sources.
Wells are defined as part of the water supply system within the instructions (Paragraph 5 subparagraph g ).
Pollution as used in these Standards, means the presence of any foreign substance (organic, inorganic, radiological or biological) in water which tends to degrade its quality so as to constitute a hazard or impair the usefulness of the water.
The well fields for Tarawa Terrace were constructed across the street and down gradient of known potential (and real) pollution sources such as ABC One Hour dry cleaners, auto repair shops and gas stations. Furthermore, these businesses were on septic tank systems (City sewer was not installed until the late 1970's). According to a hydrological survey in 1959, ground water runs down gradient to the nearest stream or river. This means that water would soak into the soil from these businesses and then run through the Tarawa Terrace well fields and into the New River.
When the definition of a health hazard was written into the BuMed definition, the well fields at Tarawa Terrace were the perfect example of what not to do!
I urge everyone that reads and places posts on this site to go out and educate yourself. I recently discovered all of this just 7 months ago shortly after I was diagnosed with male breast cancer. I have only begun to scrape the surface of this tragic story. Thanks to the efforts of people like Jerry and Tom, it was not swept under the rug and the story did not disappear into oblivion as certain people within the USMC, DoN, and DoD would hope. Do not rely on the official "version" of events. READ the documents yourself and make intelligent observations. Avoid conjecture and back what you say by proven facts.
