While iron is a well-known issue in groundwater, manganese
is an often-forgotten, but troublesome well water issue.
There is no federal Maximum Contaminant Level (MCL) for
manganese, but there is a secondary MCL for manganese of
0.05 mg/L. This is considered an aesthetic level, meaning
that water with manganese levels over 0.05 mg/L could lead
to staining, or a blackish color, on bathroom fixtures or
Iron, and to a lesser extent Manganese, are common in well
water sources across the US. The main complaint with these
metals is the reddish/orange or brown/black staining on laundry and
appliances. Irrigation water containing iron and manganese
will also cause orange staining on buildings, fences and
Aside from iron staining problems, drinking water containing
high iron and manganese can have a bitter metallic taste.
Our filter systems are designed to remove iron and manganese
to prevent staining and provide better drinking, cooking, and all water uses.
RainDance Water Systems has extensive experience treating
well water supplies and offer many types of water filters
and softeners specifically designed to treat problem well
water. Please Contact
Us to help you with your iron and manganese
are iron and manganese?
(Fe) and manganese (Mn) are metallic elements present in
many types of rock. Both are found naturally in ground
water in most if not all regions of the US. Aesthetic
levels for iron in drinking water is less than or equal
to 0.3 mg/L or ppm while the level for manganese in
drinking water is less than or equal to 0.05 mg/L or
ppm. Water with high levels of iron and manganese may
cause staining on plumbing fixtures and laundry. High
can cause off color, bad bitter tastes, and rust flakes
in the water. Similarity, manganese typically form black
particles and also give the water an off color and
Calcium & Mangnesium Hard Water
is hard water?
that is hard contains calcium and magnesium compounds.
Rain water is naturally soft - it does not contain any
minerals, but as it seeps through the ground it can pick
up minerals, such as calcium and magnesium compounds,
from the soil and rocks it passes through. If rain water
passes through soft rocks like chalk or limestone, it
picks up these minerals. If it passes through hard
rocks, such as granite or through peaty soils, it does
not pick up these minerals and so remains soft. Hard
water causes pipes to scale to collect in coffee makers,
dishwashers and washing machines. If the scale collects
in hot water haeters it shortens their life and makes
appliances less efficient. It is also more difficult to
work up a lather from soap, washing up liquid and
Hydrogen Sulfide Water Odor
is sulfur water?
in your well water supply is easily recognized by its
offensive odor. Hydrogen sulfide gas causes "rotten-egg"
or sulfur water smell. High concentrations can also
change the taste of the water. As well as, corrode
metals such as iron, steel, copper and brass. Hydrogen
sulfide amounts of 0.5 mg/l or more are usually noticed,
even in cold water. Wells drilled in shale or sandstone,
or near coal or oil fields often have hydrogen sulfide
present.Hydrogen sulfide may also be produced when
sulfate in well water converts to hydrogen sulfide.
Certain non-disease-producing bacteria (sulfur bacteria)
use the oxygen in the sulfate to form hydrogen sulfide.
Total Dissolved Solids, Salts In Well Water
What is TDS?
Total dissolved solids
(TDS) is a measure of the total amount of all the
materials that are dissolved in water. These materials,
both natural and anthropogenic (made by humans), are
mainly inorganic solids, with a minor amount of organic
material. Depending on the type of water, TDS can vary
greatly from a few milligrams per liter to percent
levels (tens of thousands of milligrams per liter).
Seawater contains 3.5% (35,000 mg/L) TDS. Elevated TDS
levels are often due to natural environmental features
such as: mineral springs, carbonate deposits, salt
deposits and sea water intrusion, but other sources may
include: salts used for road de-icing, sewage, drinking
water treatment chemicals, stormwater and agricultural
runoff, and wastewater discharges. The U.S.
Environmental Protection Agency's (EPA) Secondary
Drinking Water Standards recommends that the TDS
concentrations in drinking water not exceed 500 mg/L
based on taste and aesthetics.
National Secondary Drinking Water Regulations (NSDWRs or
secondary standards) are non-enforceable guidelines
regulating contaminants that may cause cosmetic effects
(such as skin or tooth discoloration) or aesthetic
effects (such as taste, odor, or color) in drinking
water. EPA recommends secondary standards to water
systems but does not require systems to comply. However,
states may choose to adopt them as enforceable
