For more than a decade, the existing EPA lead and copper rule has enabled criminal behavior by our environmental cops, supporting false claims of water ‘safety’ even as thousands of children were being lead poisoned.*
So how can future such calamities be prevented? The first step is identification of the problem.
Detection in Lead-Challenged Communities
Community monitoring starts with the PWS (public water system) distribution system, with a monitoring grid in the water main, accessed through any public or private water users. A secondary monitoring level can be in the pipes feeding off the main line and leading to (a) schools, (b) daycares, (c) hospitals, (d) public buildings, (e) apartments and (f) residentials. A tertiary level can be at multiple locations within a building. A web-based plot will show a real-time lead concentrations levels at nodes on the grid.
The cost of each monitor will be about $400.
Detection of lead in a drinking water pipe can trigger a sequence of events:
- Close drinking fountains and issue bottled water,
- Treat or replace the offending pipes,
- And install a point-of-use [POU] treatment system together with a monitor at the outlet to ensure that it functions properly and provides an alert when servicing is necessary. The Quansor POU filtration system is discussed here.
