Water Testing For Metals.
It is common practice to test water for metals, this could be for drinking water reasons, limits on the levels prohibited in waste water or to establish the scale potential of the water. To make the provision of these types of water tests simple, Feedwater has created a number of metals analysis packs which include the sample kit and freepost return to our chemistry laboratory for analysis.
All of these analysis packs are available for order online in our web shop.
Drinking or Potable Water Metal Analysis
The Water Supply regulations of 2010 issue a list of metals and heavy metal limits which should not be exceed in drinking water. These guidelines may be of interest to those with private water supplies such as wells, boreholes or springs where the water has not be treated prior by the water utilities.
|Metal Parameter||Maximum allowed |
in drinking water
|The point where the
legal standards apply
|Lead (Pb)||10 µg/l||Consumers' Taps|
|Boron (B)||1.0 mg/l||Consumers' Taps|
|Chromium (Cr)||50 µg/l||Consumers' Taps|
|Mercury (Hg)||1.0 µg/l||Consumers' Taps|
|Arsenic (As)||10 µg/l||Consumers' Taps|
|Cadmium (Cd)||5.0 µg/l||Consumers' Taps|
|Copper (Cu)||2.0 mg/l||Consumers' Taps|
|Antimony (Sb)||5.0 µg/l||Consumers' Taps|
|Nickel (Ni)||20 µg/l||Consumers' Taps|
|Selenium (Se)||10 µg/l||Consumers' Taps|
|Aluminium (Al)||200 µg/l||Consumers' Taps|
|Manganese (Mn)||50 µg/l||Consumers' Taps|
|Iron (Fe)||200 µg/l||Consumers' Taps|
|Sodium (Na)||200 mg/l||Consumers' Taps|
All of these parameters are part of the Potable Drinking Water Metals Analysis Pack available on the Feedwater web shop.
Waste Water Metals Analysis
Some industries can be heavy water users and have to adhere to strict limits on what is discharged within their effluent water including the metal content. Our waste water metals package includes typical metals that are picked up by leachate.
If you require a more comprehensive metals analysis we also do a general metals package which includes all metals.
To establish the scaling potential of water you can test for group II metals from the periodic table, these include:
Feedwater can test for a variety of chemical and microbial parameters, visit our laboratory analysis page to see the full list of what we can test for. Our Micro Lab is UKAS accredited for Legionella & other micro analysis.
