I recommend going to your local wastewater or water plant if you just need a couple pH's. It doesn't cost them anything and most would be glad to help a taxpayer that votes for their boss. I'm sure you could buy lunch for a more stubborn individual. PS the test is for soil pH is a 50/50 mixture of the soil and DI water by volume. You could do this pool pH strips too. Alkalinity and solids are other tests that some may be able to help with. DO is harder because it should be taken at the source, but if you dip the container completely full and cap, being careful not to shake it, run the test as quickly as possible, and not change temperature too much it should give you an idea.
