Ipso

Apologies if I am in the wrong place. I live up a mountain in Wales. My water supply comes from a spring in the rock above my house. In order to make some repairs I used some "Epoxy Repair Putty" as the packet claimed, "For underwater application ...." I subsequently read the cautionary note which said: Contains BISPHENIL A - (EPICHLOHYDRIN) (REACTION PRODUCT) The water passes through a big settling tank/cistern before entering the house and going through a 10 micron filter and a UV sterilizer. I am now worried that I am poisoning everybody. Should I analyze the water. If so, to whom should I speak? Thanks in anticipation Richard
