Lead tests in water

How do you test lead levels in water to give a quantitate result, not just whether lead is preasent or not? Where do you get lead testing equipment? Provide an equipment list, a list of chemicals and method. Note we have a colormeter at college.

A test for Lead levels in water
A method of analysis that can be used to test lead levels in water is inductively coupled plasma mass spectrometry (ICP-MS), a new and powerful method of analyzing samples for trace metals, including lead.
ICP-MS is the method of choice for the determination of lead in surface water, ground water, and effluents. ICP-MS is now recognized and is gaining complete acceptance by most regulatory agencies. Methods are fully described under US EPA 200.8. Click on the link 600R94111 Methods for the Determination of Metals in Environmental Samples, Supplement 1 and a very detailed report is given on this method.

The ICP-MS instrument consists of a conventional ICP torch (mounted horizontally rather than vertically) with the usual sample uptake and nebulizing devices. ...

Solution Summary

A method of analysis that can be used to test lead levels in water is inductively coupled plasma mass spectrometry (ICP-MS), a new and powerful method of analyzing samples for trace metals, including lead. Using ICP-MS, scientists are able to analyze a large number of elements, including lead, simultaneously to detection levels that are lower than those established for the analysis of drinking water. This group includes essentially all elements of environmental concern and is applicable to most waters, effluents and leachates. Lead is able to be detected as low as 0.1 micrograms / Liter of water. 475 words.
