EPA Method 150.1:
pH in Water by Electrometric Method. Official Name: pH, Electrometric Method

Summary:
The pH of a sample is determined electrometrically using either a glass electrode in combination with a reference potential or a combination electrode.

Scope:
This method determines the pH of drinking, surface and saline water; and domestic and industrial wastes and acid rain (atmospheric deposition).

Citation:
Methods for the Chemical Analysis of Water and Wastes (MCAWW) (EPA/600/4-79/020)

Interferences:
(1) Sodium error may bias results at pH > 10 unless a "low sodium error" electrode is used. (2) Coatings of oily material can impair electrode. (3) Temperature effects.
