Some people live in older homes where the plumbing may still contain copper and/or lead pipes. If the water entering those residences has a low pH value, meaning the water is acidic, the possibility definitely exists that the water may corrode the piping and pull dissolved and potentially dangerous amounts of metals into itself.
Maximum Contaminant Levels
For copper, the USEPA suggests that people ingest drinking water containing no more than 1.3ppm (mg/L) of free dissolved copper. Health officials have determined that short term exposure to high levels of dissolved copper in drinking water can cause gastrointestinal distress and that long term exposure can result in liver and/or kidney damage.
When it comes to maximum contaminant level for lead in drinking water, the USEPA set the limit at 15ppb. Routinely ingesting higher quantities of lead in water may result in delays in physical or mental development and in infants and children. Problems with attention span have also resulted. In the case of adults ingesting higher than acceptable amounts of lead in drinking water, kidney problems and high blood pressure have resulted.
Acidic Water Causes Other Problems
Not treating, or correcting the pH of, acidic water can result in costly corrosion problems in plumbing and it may also drastically shorten the life expectancies equipment that uses water such as dishwashers, washing machines, hot water heaters, etc.
Treating Acidic Water
If you have acidic water and wish to treat it, installing a device such as a Whole House Acid Neutralizing Water Filter will help to keep your water’s pH level in an acceptable range.
The Acid Neutralizing Water Filter works by slowly dissolving calcium carbonate into water with a pH level below 6.8. The dissolved calcium carbonate acts as a pH increaser.
According to the manufacturer of this unit, Crystal Quest, the calcium carbonate media in the tank will last approximately 2 to 3 years and the system has a backwash feature to help prevent compaction which would impede the flow of water through the system.
