The hardness in groundwater in Santa Clara County averages over 250 mg/L. By comparison, the average hardness of the District’s treated surface water is less than 120 mg/L.
Per recent reports, Santa Clara groundwater ranges from 10mg/L of hardness to nearly 600mg/L, averaging 280 mg/L. Treated water in the area ranges from 30 to 280 mg/L, with an average of 105 on the hardness scale. The math is simple: Santa Clara water ranges from moderately hard at best to very hard.
California Water Hardness by City At 320 PPM, San Jose water is considered very hard based on the USGS Measures of Water Hardness .
The City of Santa Clara is committed to providing you the water consumer, with a safe and reliable supply of high quality drinking water .
Hardness is most commonly expressed as milligrams of calcium carbonate equivalent per litre. Water containing calcium carbonate at concentrations below 60 mg/l is generally considered as soft; 60–120 mg/l, moderately hard; 120–180 mg/l, hard; and more than 180 mg/l, very hard (McGowan, 2000).
Almost all of Massachusetts has soft to slightly hard drinking water . The MWRA supplies drinking water to 42 communities in greater Boston and the Metro West area. MWRA water comes from reservoirs in central and western Massachusetts and is considered soft , with a hardness of about 15-20 ppm.
In January 2014, the governing board approved rules banning the new installation of water softeners that use sodium, or potassium and discharge the salt solution into sewer lines. As of August 2014, salt water softeners have been banned in 25 California communities.
Hard water is not a health hazard. In fact, the National Research Council (National Academy of Sciences) states that hard drinking water generally contributes a small amount toward total calcium and magnesium human dietary needs.
In summary, San Francisco tap water is still legally safe to drink but to be on the safe side, an active carbon filter such as TAPP could be used.
The water is completely safe to drink any place in the US from the tap . Some areas the water tastes better than others, but it is all safe . But it seems everyone in LA drinks bottled water anyway.
About 55 percent of Santa Clara County’s water supply comes from hundreds of miles away – first as snow or rain in the Sierra Nevada range of northern and eastern California, then as water in rivers that flow into Sacramento-San Joaquin River Delta or directly to water conveyance systems.
Water hardness can be easily measured using a simple soap test kit that will measure in “grains of hardness ” (a little bottle with a line marked on it which you fill to the line with water , add a drop of soap, and shake to look for suds. More drops of soap – more degrees of hardness ).
What is the Ideal Water Hardness ? 0–3: If your hard water test strip indicates that your water is between 0–3 grains per gallon, your water doesn’t require softening. 3–7: Water between 3–7 gpg is moderately hard, causing spotty dishes and dry skin.
Unlike hard water , soft water is free of harsh minerals that can damage your home and your body. In other words, it is more gentle on your body and your home. Without calcium and magnesium, soft water can prevent scale buildup around your home including your appliances and pipes.
The general answer is yes, you can drink Boston tap water and surrounding areas. In 2014 it even won the AWWA water taste test beating NYC. However, there are health risks such as lead, bi-products from chlorine and microplastics. Therefore a point of use water filter such as TAPP can be a good idea.
BOSTON — Boston may have to revisit its choice of “Dirty Water ” by The Standells as its unofficial anthem, because the city has the best-tasting tap water in the nation according to a national water association.
The primary hard water minerals found are magnesium and calcium (the hardness minerals), while iron and manganese (“the stainers”) can also be found in Newton , MA water , mostly in private wells. Hard water interferes with almost every cleaning task, from doing the laundry to washing dishes to taking a shower.
