1.0 SCOPE AND APPLICATION METHOD 9045D SOIL AND WASTE pH 1.1 This method is an electrometric procedure for measuring pH in soils and waste samples. Wastes may be solids, sludges, or non-aqueous liquids. If water is present, it must constitute less than 20% of the total volume of the sample. 2.0 SUMMARY OF METHOD 2.1 The sample is mixed with reagent water, and the pH of the resulting aqueous solution is measured. 3.0 INTERFERENCES 3.1 Samples with very low or very high pH may give incorrect readings on the meter. For samples with a true pH of >10, the measured pH may be incorrectly low. This error can be minimized by using a low-sodium-error electrode. Strong acid solutions, with a true pH of
