What should I test for?

A few questions about your well and your area. You get a list of tests, why each one matters, the official limit and what to do next. Every statement links to its official source.

Which province is the well in?
Farm fields, livestock, manure or orchards within about 400 m (1/4 mile)?
Is anyone pregnant, or is there a baby or young child at home?
When was the well last tested?
Is it a dug (shallow, wide) well, or does the house have old lead or galvanized pipes?
Mining, industry, a landfill or a waste site nearby?
A fuel or heating-oil spill or a fire near the well?
Stains on fixtures or laundry, or a change in taste, colour or smell?
Recent flooding, or was the well recently built or repaired?
