Water Irrigation

We have water in our home cooking and secondary (irrigation) water for our system of sprinklers in our lawn. We recently installed a tap next to our garden that feeds the irrigation water, sprinkler system. We thought it would be cheaper to use irrigation water to the garden because we so much water, but now I heard that irrigation water may be dangerous to use on vegetables that we eat. Is this true?

Only if you are near a fertilizer manufacturer or other large manufacturers of dangerous chemicals. Such as pesticides, irrigation water etc. is excellent for watering gardens, but I recommend having at least two years immediately tested for hazardous chemicals. If it is cleaned up two years in a row, it's a pretty safe bet that you are authorized

It depends on what is in the irrigation water. It should not be too expensive to do a test, or check with your municipality if they have documents on the source of irrigation water.
Some chemicals may be harmful to sensitive plants. You can also contact your local garden center (or online) to check if everything you're growing a sensitivity to anything that can be in the water. The ingestion of certain chemicals can harm your health, of course, irrespective of how the results of tests on water, wash your products.

except if you have high pesticide or heavy metals in irrigation water, it should go. Have the water tested for toxins by a reputable laboratory.
