Really enjoy your podcasts. This is another great topic that needs to be a piece of the puzzle when trying to solve certain problems. I spent 24 years in the pool industry and left for 8 years... (and have now returned). In my years away, several years were spent in the industrial water treatment industry (boilers and cooling towers) and this accumulation is referred to as concentration and the u of m was cycles of concentration (COC). If make up water is 200ppm and the cooling tower had 600ppm, the COC was 3. Conductivity controllers were used to control COC using blowdown valves since conductivity concentrates up along side most impurities that are left behind. It was not 100% accurate but it is a reliable and cheap form of measuring that water's concentration level. There are many issues that can result from high concentration levels of a variety of impurities. For instance chlorides can corrode 304 stainless steel at 150ppm. Or 150ppm of Silica can cause erosion in copper at pH less than 9.0. The huge majority of pools will never have an issue related to concentration but it can happen and it needs to be understood in this industry.
