Always cook meat, especially ground meat, until the juices run absolutely clear, pink is not good enough. It is generally good for the internal temperature of a hamburger patty to reach 160 degrees F to kill all contaminating E.Coli.
Your local public water supply is required to test for lead on a regular basis. You can call them or ask for the latest issue of their Consumer Confidence Report (this will list all the constituents the supplier must test for and whether or not any contaminants were found). If you live in an older house, one which may have lead pipes or lead based solder call our lab for specific instructions and special sample bottles to have a sample analyzed.
The USEPA and the State of Wisconsin have set a Maximum Contamination Level (MCL) of 10 ppm (mg/L) nitrate for public drinking water supplies and as a guide for private water supplies. A MCL is the highest level of a contaminant that is allowed in drinking water. Nitrates are dangerous especially to infants under the age of 6 months. Some symptoms include shortness of breath and blue-baby syndrome. Most adults are not overly affected by nitrates.
Water Care Specialist, Plumbers, and Well Installers are all good sources for treatment systems for nitrates. There are several systems available to treat water for nitrates, and these professionals will be able to suggest the best system for your needs.
What you are most likely seeing is a build-up of hard water scale. Look in your tea kettle and see if you find the same substance there. Hard water scale is the result of water precipitating the natural calcium or magnesium compounds from your water. Water that is hard is not a health threat, it is more an esthetic issue. Some people prefer the taste of hard water to softer water. The colors you may be seeing are the iron (reddish) or copper (greenish) also precipitating out of your water. If you have your water tested for hardness you can interpret the results as follows:
0 ppm Very Soft
50 ppm Soft
125 ppm Hard
200 ppm White buildup will occur
250 ppm Very Hard
