Ask The Expert: UV & lake water
Question: Q: I would like to know how effective ultraviolet (UV) technology is for treating lake water. In our cottage, the water is supplied by the lake (tap, shower, etc.). We have been told that we basically have two choices for making our water drinkable -- either digging a well or using UV technology. What are your thoughts on both alternatives? Would the UV provide us with a truly safe water to drink? Thank you.

Answer: Q: It's not clear from your email as to whether or not your problem is related to microorganism contamination, which is more likely in surface water than groundwater. If it is, however, ultraviolet should work effectively provided that the water is adequately filtered to remove suspended solids and the UV unit is sufficiently maintained. There are several manufacturers of high quality systems that could be of help to you in this application. We would suggest you check our online Buyer's Guide, which provides an extensive list of UV equipment suppliers (see www.wcponline.com). Let us know if we can be of further help.
