FREE Water Testing !
There could be many things lurking in your water that you do not know about. Call Minnesota Water today for a FREE total dissolved solids (TDS) water testing.

TDS affects everything that consumes, lives in or uses water, from fish and planets to plumbing and laboratories.

For people, the lower the TDS level in the water you drink, the more efficiently your body’s cells are hydrated. The higher the TDS level in the water, the greater the probability of harmful contaminants that can pose health risks or hinder the absorption of water in the body.

Why Should You Measure the TDS Level in Your Water?
The EPA Secondary Regulations advise a maximum contamination level (MCL) of 500mg/liter (500 parts per million (ppm)) for TDS. Numerous water supplies exceed this level. When TDS levels exceed 1000mg/L it is generally considered unfit for human consumption. A high level of TDS is an indicator of potential concerns, and warrants further investigation. Most often, high levels of TDS are caused by the presence of potassium, chlorides and sodium. These ions have little or no short-term effects, but toxic ions (lead arsenic, cadmium, nitrate and others) may also be dissolved in the water.
Even the best water purification systems on the market require monitoring for TDS to ensure the filters and/or membranes are effectively removing unwanted particles and bacteria from your water.
The following are reasons why it is helpful to constantly test for TDS:

High TDS results in undesirable taste which could be salty, bitter, or metallic. It could also indicate the presence of toxic minerals. The EPA’s recommended maximum level of TDS in water is 500mg/L (500ppm).
Filter performance
Test your water to make sure the reverse osmosis or other type of water filter or water purification system has a high rejection rate and know when to change your filter (or membrane) cartridges.
Hardness (and Water Softeners)
High TDS indicates Hard water, which causes scale buildup in pipes and valves, inhibiting performance.
A constant level of minerals is necessary for aquatic life. The water in an aquarium or tank should have the same levels of TDS and pH as the fish and reef’s original habitat.
TDS is the best measurement of the nutrient concentration in a hydroponic solution.
Pools and spas
TDS levels must be monitored to prevent maintenance problems.
High TDS levels could impede the functions of certain applications, such as boilers and cooling towers, food and water production and more.
Colloidal silver water
TDS levels must be controlled prior to making colloidal silver.
Coffee and Food Service
For a truly great cup of coffee, proper TDS levels must be maintained.
Car Washing and Window Cleaning
Have a washer with a spotless rinse? An inline dual TDS monitor will tell you when to change the filter cartridge or RO membrane.
