Retrieves water quality results for a monitoring site from the Water Quality Por
Retrieves water quality results for a monitoring site from the Water Quality Portal and normalises them into a comparable shape. The real work is units: the same measurement appears there as mg/L, ug/L, ppm and mg/l in mixed case, and combining them unchecked puts factor-of-thousand errors into any statistic built on top.
