Hello, Marilyn, and thank you for your inquiry. The SenSafe Water Quality Test Kit contains the following:

• 2 Alkalinity, Total
• 1 Bacteria,Coliform in Water
• 2 Chloride
• 2 Chlorine, Free
• 2 Chlorine, Total
• 2 Copper, Total
• 2 Hardness, Total
• 2 Hydrogen Sulfide
• 2 Iron
• 1 Lead
• 2 Nitrate/Nitrite, as Nitrogen
• 1 Pesticide
• 2 ph
• 2 Sulfate

The kit does not contain tests for manganese but that kit is available on its own. We do carry a manganese test as a standalone kit, though.

Regarding magnesium, that value is included in the total hardness reading given by the total hardness test included with the SenSafe Water Quality Test Kit. Note: The test gives a sum of calcium hardness and magnesium hardness levels, not individual concentrations.

And finally, regarding performing testing for the purpose of determining the quality of your water so you can figure out the best treatment option, if you suspect that your water has potentially significant problems and/or health risks, then home water test kits should serve as a preliminary tests only and you should probably use the services of a certified water testing laboratory before investing in a water filtration system.

If you do not wish to use the services of a local water testing laboratory (which your local health department could help you locate), then companies like National Testing Laboratories offer mail-in water testing services that provide results from a certified water testing laboratory usually within 10 business days.

Good afternoon, Jeanette, and thank you for your inquiry. The links below will allow you to learn more about the test procedure for  SenSafe Manganese Check:

Regarding accuracy, we really have not heard any complaints from users of the product. When we experimented with it years ago we found that it did a pretty decent job... for a dip-n-read style of test.

If you need something with greater precision, range, etc., then we suggest considering a product such as the following which provides a digital readout of results:

The Well Water (Driller) version of the eXact Micro 20 Handheld Water Testing Meter (information available on this page: http://www.filterwater.com/pc-458-32-exact-micro-20-water-tester-kit.aspx) comes with testing materials for a number of important water quality parameters in addition to manganese.

Is Manganese a Health Hazard?

As a general rule manganese in drinking water does NOT present a health hazard, though in great enough concentration ANYthing could pose a threat to human health.

Typically manganese in water presents itself as more a nuisance for laundry since it may cause black staining and for that reason water professionals suggest keeping its levels below 0.05mg/L (ppm).

Filtering Out Manganese?

Should you find yourself in a situation where manganese levels in your water supply give you trouble, the following Propur water filters have been tested by an independent lab to reduce manganese levels in drinking water by >99%.
