THE BEST WAY TO TEST FOR BACTERIA
The R-CARD™ is completely self-contained, meaning no more petri dishes or filtration devices. Results are visible in as little as 15 hours.

This product is worth the money! I have been using R-cards with 1ml samples and although it works great for safety tests, it doesn't give us the resolution we'd like for spotting septic leaks into our lake. Using 100ml samples really helps. The setup is simple (once one understands to remove the blue cover on the filter paper ;>) ) The funnel leak I had last time was my mistake. I wish I could delete my last review. More importantly than the product, this is likely the most responsive, helpful company I've ever worked with. VERY refreshing and appreciated. Kudos.
At Choctawhatchee Riverkeeper we still feel that the R card products are the best for our needs. At this time we are training citizen volunteers to do testing so that we might sample stream, river and lake recreational sites more often. We use the ECC R cards and post all results on The SWIM Guide as well as notify the public.
The protocol we use is supported by Alabama Water Watch and is approved for first alert testing by Region 4 USEPA.
