As part of our current programme of borehole drilling, we are going to implement post-construction water quality testing (we already test for a full range of parameters at time of construction) at sites we have constructed this year and in previous years. Ideally we would like a test that is as simple as possible so field staff can carry it out on site (ruling out WagTech, which we have, etc), and provides rapid feedback to water users. We are aware of some kits which allow this (like the swirl bags included in this kit from mwater: http://www.mwater.co/kits.html) but never used them.
Does anyone have any experience of such kits that may be recommendable to provide an almost immediate result? Once you start researching on the web it quickly descends into a minefield of various options!
