We recently received a question from 'JimP' who asked, "On your metals test kit is lists "Cadmium, Cobalt, Cupric Copper, Ferrous Iron, Lead, Mercury, Nickel, Zinc and other metals with a +2 state valence shell.  Can you please tell me what the other metals are?  I am looking for all listed plus titanium and tin."

Thank you, Jim, for your inquiry.

The Heavy Metals Check product detects, as you quoted, "Cadmium, Cobalt, Cupric Copper, Ferrous Iron, Lead, Mercury, Nickel, Zinc and other metals with a +2 state valence shell" according to the manufacturer.

Regrettably the manufacturer has not made much more information than that available to the public... and yes, we have asked more than once in the past.

As far as detecting tin and titanium goes, at this time we do not know of a simple dip and read test that detects those metals. The manufacturer of Heavy Metals Check manufactures a line of meters that MAY offer ion selective detection of tin and titanium, though, so that may be worth checking out.  We suggest visiting www.sensafe.com and exploring the capabilities of their latest water testing meters.

Mail-in water testing services

Companies such as National Testing Laboratories offer mail-in water testing services that provide prompt water test results from accredited laboratories in approximately 10 to 14 business days and have a range of testing packages available that range from very basic to fairly comprehensive (though we do not see tin or titanium in any of the testing packages we carry...)
