I recently got the potable water tested at my residence since we recently became parents. This was water supplied by the BMC in my building. I Came across this company on google and called them. I unknowingly sent the filtered water for testing(although I was informed by them) . They were nice enough to call(one Mr. Page) me and confirm this and I sent them the sample again. They actually sent me two results for both the water samples! This service is a boon for end users. I was very happy with the results and I think I will be getting these tests done annually.
