Have your local health department or a lab test your water for bacteria, and If your Report shows a P next to either E.coli or Coliform Bacteria, that means there is the Presence of Bacteria & NO amount of this Bacteria is acceptable so the water MUST be treated to kill the bacteria to make it potable!
Optometrists also test for glaucoma and other eye diseases, and diagnose conditions caused by systemic diseases, such as diabetes and high blood pressure, referring patients to other health practitioners, as needed.

An optometrist---not to be confused with an ophthalmologist---is a general eye care practitioner, somewhat like a dentist for the eyes. Optometrists can give eye exams, prescribe medications and perform other duties relating to routine eye care. An optometrist is different from an ophthalmologist in that only ophthalmologists are required to have a broad knowledge of general medicine and only they can perform major eye surgery.
