Frequently Asked Questions

I want to test my water, but how does it work?


1) Give us a call to see what testing kit you'll need for your situation. 2) Collect water sample, or have someone from TCWC collect it for you. 3) Bring samples into the laboratory. 4) We analyze your water for the testing that's needed. 5) You receive a full report with our findings




How do I know which tests are needed for my water?


Call us at (952) 935-3556 and we'll be able to asses your situation and what tests are needed.




Can I collect my own water samples or does TCWC need to do it?


That depends; if you are purchasing or selling a house some loans (VA & FHA) will require a third party to collect the sample to ensure there is no bias in the results. Otherwise you are able to collect the water samples by following some simple instructions you can find here. If you don't feel comfortable collecting the sample or simply just don't have the time, we'd be more than happy to come to you and retreive the sample!




I don't have a science background, will I be able to do an at home kit?


Yes! You don't need a science background to be able to collect your own water, it is simple and easy to do. Click on this link to download our instructions.




My water looks, smells, and tastes great - do I need a water test?


Yes, some of the of the most harmful contaminants have no obvious odor, color, or taste to them.




I have a private well that was tested when it was installed, do I need to retest?


Well water should be tested on an annual basis since contaminants can seep into the ground water and into your drinking supply without you even knowing it!




I have a water filter, how would I be able to tell if it's working or not?


Unless you get your water tested, you wouldn't. Variations of water condition can affect the performance of a filter and maintenance issues within the filter can change how effective it is.




I can get water tests from the company that I bought my filter from, how is this different?


Twin City Water Clinic is an independent, certified lab that has nothing to gain from your water results unlike the filter company. We do not sell water treatment products, nor are we affiliated with anyone who does.




What could possibly contaminate my drinking water?


There are many potential causes of water contamination. The most common threats would be:

  • Lead pipes in the home
  • Septic system leaks
  • Living close to farm fields, brownfields, or other agricultural land
Other potential threats that could be near you:
  • Mines
  • Gas stations
  • Old cemeteries
  • Dumps
  • Improper disposal of paints, motor oils, etc on private land
  • Recreational use of the public water supply
  • Acid rain
  • Decaying matter or other natural contamination




How many types of contaminants are there?


While there are many specific types of contamination, it can be sorted out into four broad categories:

  • Microbial Pollutants
  • Inorganic Chemical Pollutants
  • Organic Chemical Pollutants
  • Radiological Pollutants
What type of contamination you have will determine what solution you need to use to correct it.




My water doesn't taste good, but the results came out fine. What does this mean?


There are two types of water problems 1) Primary - this affects your health 2) Aesthetics - this affects the taste, look, or smell of the water Strange as it may seem, you could have an aesthetic problem that makes your water not taste good but doesn't actually pose as a health risk. Two common examples are heightened sulfur levels that make your water smell like rotten eggs or high iron levels that could stain your sink or shower.




What do I do if I find out my water is unsafe?


Because there are many different types of problems, each problem must be addressed separatley. Immediately switch to bottle water for all consumption until the problem is addressed. This includes drinking, cooking, washing produce or dishes, giving water to pets, or using it to brush your teeth. Once the problem is solved, be sure to have follow up water tests done.
