Episode 130: Understanding Water Quality with Les Evans

Irrigation is one of the most underrated aspects of cultivation and understanding water quality, dissolved oxygen, and best practices will make a HUGE difference in plant health. My guest this week is Les Evans from Dramm, to answer all my questions about water. Les has a degree in Biological Engineering, with a concentration in Water/Soil & Environmental Engineering from NC State University, and 29 years of industry experience helping growers, of all types of crops, with their environmental and water quality challenges. Les' day-to-day involves supporting the Dramm sales team and their customers with water treatment designs that maximize investment while minimizing environmental impact. When he's not at his desk, he can be found planting perennials with his family, or running the NC Mountains-to-Sea trail system a stone's throw from his home in Raleigh.

Really interesting stuff. Currently I have 4 venturi valves hooked up to my aeration pump. Going to need to get a DO meter and perhaps dial it in to determine when I need to add and when I don't. Great episode

Good informative episode, but what about rain water? Is it safe to use? In my opinion it is the best but there must be pollutants in it. Might be an entire episode?

In general I think it’s pretty safe. As I understand it the issues usually arise from what the water comes into contact with during collection or how it’s stored. Some areas may have issues with rain water and it would be worth checking pH and alkalinity. I will try and follow up with Les though on a future podcast if folks have questions!

Similar question. What is the DO of rain water? I imagine it is quite high when it hits the ground. I assume once you store it though it loses its O2 content?

Jared from Dramm here! We love rain water but you're right, the surfaces that the water hits before being collected may bring things into your system that you don't want such as pathogens or algae spores, dust, pollen, dirt.. All the stuff. We collect rain water all the time in ornamental horticulture. Depending on the crop and value, simple filtration may be enough all the way to more integrated approaches with very fine filtration and oxidizers such as ozone to provide ultra clean, healthy irrigation water.

@@jaredbabik7653 there were some questions on our IG post regarding rain water and DO levels, if you get a chance, maybe you could take a look? Thank you!
