As I write this, thankfully unaffected, it's amazing to watch the cross-scale effects created from things that exist on a tiny scale—specifically, the spread of the coronavirus (COVID-19) has sent powerful waves across seemingly all societal scales. Water is also something very small that creates powerful effects across a wide range of scales, but in comparison to the immediate but hopefully moderating threat of coronavirus, we should appreciate that the scale of water is orders of magnitude more significant. When it comes to water, scale can take on multiple meanings, but here I mean the scale of water in space and time. Spatially, we can start with global patterns of water and energy moving through awesome natural phenomena. Climate change—which is a global response to an amalgam of local actions—manifests itself as it amplifies water's movement in extremes. Moving down in scale, the emphasis shifts more from quantity to quality, and we see the effects of water pollution on local communities and ecosystems. Going down into the micro- to nano-levels, chemical and biological effects become prominent, and thousands of microscopic contaminants and pathogens (including viruses) can lead to widespread sickness at trace concentrations. Temporally, water scales range from microseconds to centuries, and they are regularly considered in lengths of heartbeats, seasons, and human lives. Utilities must abide by their own annual water calendars as well as seasonal and diurnal patterns. The expected life of water system assets can range 50–100 years while the technologies that manage them seem to change annually. Ultimately, water professionals must keep in mind time scales such as those on the levels of sea level rise, an afternoon monsoon, a bad news cycle, the time frame to raise water rates, a summer or several years of drought, waiting to get sample results back, and repairing a major leak. There are political scales of water, too, ranging from international agreements to local water ordinances. At the watershed/regional/basin level, there is drought, extreme weather, and wildfires, forces that draw people together and create a level of equity among those who share an area's resources. I think this is the most significant scale for water because even with regulation from higher levels, this is where decisions really manifest themselves. It's clear that water isn't ever simply a local or global issue. Water is cross-scale, so water professionals should look above, below, and in the pages of Journal AWWA for solutions to cross-scale challenges ranging from coronavirus to climate change. This month's Journal AWWA features a range of topics, including potable water reuse, lead and copper management, laboratory analysis, and much more.
