Serratia Marcescens
Pink mold
S. Marcescens are airborne bacteria. The bacteria form pink stains in toilet bowls, shower heads, sink drains and tiles.
Life threat:
It has been shown to cause a wide range of infectious diseases, including urinary, respiratory, and biliary tract infections, peritonitis, wound infections, and intravenous catheter-related infections, which can also lead to life-threatening bacteremia(a condition where bacteria are present in the bloodstream).
The issues caused by Lead, Manganese, Iron and Calcium
Lead and Manganese
LEAD
If lead is present in your pipes and sediment is slowly deteriorating those pipes, lead can be released into your drinking water.
Health concern:
It is especially harmful for pregnant women, infants, and young children. Even a small concentration of lead in your water can accumulate in your body over time, causing damage to your heart, brain, bones, liver and kidneys.
MANGANESE
Danger of high levels of manganese in your water:
Drinking water may cause problems with memory, attention, and motor skills. Infants may develop learning and behavior problems. Older adults may develop a disorder similar to Parkinson's disease.
It also may cause black stains in toilet bowl, dishwasher, or fixtures.
Iron
Danger of high levels of Iron: In hard water the existence of iron along with certain kinds of bacteria can form a smelly biofilm (reddish brown or yellow slime) that cause an offensive odor and clog plumbing. It may leave reddish or brown stains on plumbing fixtures, bath tubs, shower walls and doors, tableware and laundry that are very hard to remove. The water with a high concentration of Ironis discolored or rusty, and it has a metallic or bad taste.
Oxidation created by iron and oxygen reaction with water produces rust. Rust may eventually eat away at the metal until it completely disintegrates.
Health concern of high levels of Iron:
The Iron bacteria create conditions for the organisms naturally occurring in shallows soils and groundwater and then introduced into a water system when it is constructed or repaired to cause diseases such as brain damage, DNA damage and cancer, heart or liver failure, and hemochromatosis.
· It also may cause skin issues damage of skin cells and eczema, make hair brittle and discolored.
Calcium
Dissolved calcium (or magnesium, other minerals and salt)salt in the water flows through showerheads and faucets and gradually forms a white crusty-looking build-up called lime scales (lime deposits or lime film) that are really hard to clean away.
The main concern of high levels of calcium in your water is that it has a negative impact on your plumbing system.
It causes frequent build-up of soap scum in the showers and sinks, film that builds up on your body or hair while showering, discoloration of clothing or spots on dishes while washing using hard water.
Damage of household appliances:
The gradual accumulation of lime deposits also can quickly disable household appliances, such as a coffee maker, iron, dishwasher and washing machine.
Health danger of a high concentration of Calcium:
You risk developing Hypercalcemia that affects the central nervous system, and can disrupt the electrical impulses that govern your heartbeat. You also risk developing kidney stones.
