We're often asked why we started with a technology to measure how much water is in the ground or in a well, instead of the quality of the water in it. The simple answer is that quantity leads to quality, or better, lack of quantity leads to lack of quality.
You've heard the old expression, the solution to pollution is dilution? It applies to groundwater.
Groundwater is usually potable because it has been cleaned, naturally, by earth, and it has been stored in a clean place. If we manage it poorly, that is, if we allow the groundwater or the earth it is stored in to be contaminated, then we threaten the resource. Thankfully, human contamination it is something we can generally control.
Sometimes, the resource is naturally contaminated, as in Waukesha, Wisconsin where the deep sandstone aquifer delivers water containing radium, a naturally occurring chemical that also can cause cancer. This is called subsurface contamination, and the only way to prevent it is to ensure adequate recharge of the clean water source so that we don't become dependent on the lesser quality, deeper groundwater. Here's the rub: Waukesha residents didn't always drink radium-laced water. Ironically, there was a time when Waukesha was famous as a water spa resort, boasting naturally clean, good tasting groundwater that was near to the surface. Today Waukesha's supplies are tainted because the deep water is the only water left. Had surface or shallow water sources been managed more effectively, citizens wouldn't be at risk.
So Wellntel's first products help homeowners and farmers in neighborhoods, like Waukesha, understand the amount of water they have, so that they can make smart decisions that will keep it clean and renewable. Think if it like a bank statement for a savings account.
Here's a great link to learn more about subsurface contamination: http://wi.water.usgs.gov/gwcomp/find/waukesha/susceptibility.html
And here's more about Waukesha's history as the "Saratoga of the West." http://en.wikipedia.org/wiki/Waukesha,_Wisconsin
UPDATE: Here is an Michigan State University study correlating groundwater depletion with groundwater contamination in a nearby state. http://msue.anr.msu.edu/news/ottawa_county_groundwater_has_quality_and_quantity_concerns
