Default Re: Need info On Reverse Osmosis

Nitrates usually occur as a result of former agricultural operations, therefore nitrates are more prevalent in shallow aquifers. One thing i would recommend is getting the best well contractor in your area to install the well and not spare any expense here. It will very likely save you money in the long run. Make sure they grout the well properly and consider paying more for a well screened in a deeper aquifer that should be less likely to be contaminated.

RO systems will work OK for nitrates, but some ion-exchange systems may work better and be cheaper to operate and maintain. The technology for RO systems has improved quite a bit in the past few years, but so has other types of water treatment, such as ion exchange. One caveat with ion-exchange systems is to make sure you don't put the backwash water in your septic system; sometimes that can cause septic systems to fail prematurely.

If you still need a water treatment system, make sure its installed and maintained properly by a reputable firm. Make sure you sample the influent and effluent regularly to make sure that the system is working properly. Don't let them get away with sampling the system just once right after its installed. Very few states regulate water treatment companies, and sometimes they get away with some stuff that is ineffective or possibly even dangerous. A good source of local information for you should be the county health department and/or agricultural extension service. Hope this helps.
