Health Effects
|
|
Chloride
|
26
|
mg/L
|
250
|
Naturally occurring or indicative of road salt contamination
|
No health effects. The MCL for chloride is the level above which the taste of water may become objectionable.

Color
|
20
|
CoPt@pH7.4

|
Large quantities of organic chemicals; inadequate treatment; high disinfectant demand and the potential for production of excess amounts of disinfectant by-products such as trihalomethanes; the presence of metals such as copper, iron and manganese; natural color may be caused by decaying leaves and soil organic matter
|
Color has no health effects. In some instances, color may be objectionable to some people at as low as 5 units. Its presence is aesthetically objectionable and suggests that the water may need additional treatment

Odor
|
None detected
|
TON@60C
|
3
|
Organic or inorganic pollutants originating from municipal and industrial waste discharges; natural sources
|
Odor as measured by this standard procedure has no health effects; although several contaminants exert odors when they are present at levels near their MCLs. Odor is an important quality factor affecting the drinkability of water
|

Sulfate
|
9.9
|
mg/L
|
250
|
Naturally occuring
|
High concentrations of sulfate in drinking water have three effects: 1) water containing appreciable amounts of sulfate tends to form hard scales in boilers and heat exchangers; 2) sulfates cause taste effects; 3) sulfates can cause laxative effects with excessive intake. The laxative effect of sulfates is usually noted in transient users of a water supply because people who are accustomed to high sulfate levels in drinking water have no adverse response. Diarrhea can be induced at sulfate levels greater than 500mg/L but typically near 750mg/L

Corrosion of galvanized pipes; erosion of natural deposits; discharge from metal refineries; runoff from waste batteries and paints

|
Iron
|
0.13
|
mg/L
|
0.30
|
Naturally occuring
|
Iron had no health effects. At 1.00 mg/L a substantial number of people will note the bitter astringent taste of iron. Also, at this concentration, it imparts a brownish color to laundered clothing and stains plumbing fixtures with a characteristic rust color. Staining can result at levels of 0.05mg/L, lower than those detectable to taste buds. Therefore, the MCL of 0.30mg/L represents a reasonable compromise as adverse aesthetic effects are minimized at this level. Many multivitamins may contain 3.0 or 4.0mg/L of iron per capsule
|
|
Manganese
|
0.35
|
mg/L
|
0.30
|
Naturally occuring
|
The Food and Nutrition Board of the National Research Council determined an estimated safe and adequate daily dietary intake of manganese to be 2-5mg for adults. However, many peoples diets lead them to consume higher amounts of manganese, especially those who consume high amounts of vegetables or are vegetarian. The infant population is of greatest concern. It would be better if the drinking water were not used to make infant formula since it already contains iron and manganese. Excess manganese produces a brownish color in laundered goods and impairs the taste of tea, coffee and other beverages. Concentrations may cause a dark brown or black stain on porcelain plumbing fixtures. As with iron, manganese may form a coating on distribution pipes. These may slough off, causing brown blotches on laundered clothing or black particles in the water.
