_J._ Every liquid exhibiting on its surface a film of petroleum, or
  hydrocarbon, or containing in suspension, in 100,000 parts, more
  than 0.5 of such oils.

But to arrive at a fair and impartial conclusion, authorities now
agree that analyses and investigations must be often, and for a
prolonged period of not less than one year. The aim of modern
scientists, in their analyses, is to detect the amount of organic
(especially sewage) contamination. Dr. Frankland’s method is by the
estimation of organic carbon and nitrogen, while Wanklyn, Chapman,
and Smith reach their conclusions by estimation of nitrogenous
organic matter, by breaking up the organic bodies and separating
their nitrogen in the form of albuminoid ammonia. Ammonia is the
measure of that portion of organic matter not decomposed but in state
of or capable of undergoing putrefaction.

The maximum amount of free ammonia permissible in good drinking water
is .5 of a grain per 1000 gallons, and of albuminoid ammonia .9 of a
grain per 1000 gallons.

Upon the above basis the relative merits of the following waters may
be formed:


  NUMBER OF GRAINS OF SEWAGE IN EACH THOUSAND GALLONS.
