Over-Arching Perspective


I’m attracted to “big picture” vistas that put the day’s momentary developments into what at least feels like a meaningful perspective. It helps me to imagine things are more manageable than they otherwise seem to be. In reading my daily news (currently The Washington Post), I’m always on the lookout for at least two articles that fit together somehow to create a glimpse of this over-arching view. Today (Friday, 6 May) I got what feels like a pretty good peek.

First is an article about the EPA’s twenty-five year struggle to define and implement rules and regulations about lead in America’s water supply. Basically, the efforts have focused on requiring municipalities to test their water for lead on a regular basis―and then implement some kind of remediation if the lead-levels test too high. The problem lies in the complex relationship between the testing and the remediation: Testing must occur at the tap, not at the supply, because lead contamination occurs in the old, lead pipe-connections which the water, pure as it may be when it starts out, must pass through to get to the tap. The corrosiveness of the water, which is controlled by many factors and chemicals, determines how much lead is picked up along its journey through the lead-infested pipes. If the tap water tests too high, municipalities must implement a complex calculation of how to reduce the water’s corrosiveness.
