METHODS

The CONSOL R&D water laboratory is certified by the states of West Virginia and Pennsylvania to use the following methods:

pH SM 4500-H+ B :Method Summary. The activity (temperature compensated) of the hydrogen ions in solution is measured using an indicating glass electrode and a reference electrode. The potentiometric apparatus is calibrated using two different buffer solutions of known pH
Alkalinity SM 2320 A: Method summary. Hydroxyl ions present in the sample are titrated with standard acid to pH.4.5
Acidity SM 2310 B :Method Summary. Hydrogen ions present in the sample are titrated with standard base to pH 8.3.
Turbidity SM 2130 B :Method Summary. The intensity of light scattered by the sample under defined conditions is compared to the light scattered by a standard reference suspension under the same conditions.
Conductivity SM 2510 B: Method Summary. The ability of the sample solution to carry an electric current is measured (umhos/cm) in a self-contained instrument.
Total Dissolved SM 2540 C & Total Suspended Solids SM 2540D :Method Summary A portion of the test solution is filtered through a standard glass-fiber filter. The filtrate is dried to a constant weight at 1800 C. The increase in the dish weight represents the total dissolved solids. A portion of the test solution is filtered through a weighed standard glass-fiber filter. The residue retained on the filter is dried to constant weight at 1050 C. the increase in weight of the filter represents the total suspended solids
Settleable Solids SM 2540 F :Method Summary. 1-L of the test solution is poured directly into an Imhoff cone. The volume of solids that settle after 1 hour is read directly from the gradations on the Imhoff cone.
Dissolved Metals EPA 200.7 :Method Summary. The concentration of elements in a field-filtered (0.45-um) acidified sample are determined by ICPAES. Detection limits are in the 5-100 ppb range.
Total Recoverable Metals EPA 200.7 :Method Summary. The concentration of elements in an unfiltered, field-acidified sample is subjected to a vigorous digestion. Total metals (i.e. dissolved metals + particulate metals solubilized by the HNO3-HCldigestion) are determined by ICPAES. Detection limits are in the 5-100 ppb range.
Dissolved Trace Elements EPA 200.8 :Method Summary. The concentration of elements in a field-filtered (0.45-um) acidified sample are determined by ICPMS. Detection limits are in the 0.05-0.5 ppb range.
Total Recoverable Trace Element EPA 200.8 :Method Summary. The concentration of trace elements in an unfiltered, field-acidified solution is subjected to a vigorous digestion. Total metals (i.e. dissolved metals + particulate metals solubilized by a nitric acid digestion) are determined by ICPMS. Detection limits are in the 0.05-0.5 ppb range.
Chloride SM 4500-Cl- C :Method Summary. Chloride ions are titrated with standard mercuric nitrate. The solution is adjusted to s pH of 2.3-2.8 using either HNO3 for alkaline solutions or NaOH for acidic solutions. Addition of diphenylcarbazone indicates the titration end point by forming a purple complex with the excess mercuric ions.
Anions (Cl-, Br--, NO2-, NO3-, PO4-, and SO4-2) SM 4110B::Method Summary. Anions in a portion of the test solution are determined by ion chromatography with chemical suppression of eluent conductivity.
Ammonia as N SM 4500-NH3 D: Method Summary. The ammonia contained in a (what type distillation????) distilled portion of the test solution is determined by specific ion electrode.
Shake Extraction of Solid Waste with Water ASTM D3987:Method Summary. This procedure is used to simulate aqueous leaching of elements and ions. The test procedure provides for the shake extraction of a known weight of solid sample with water of a specified composition. The aqueous phase is analyzed for soluble species.
TCLP (Toxicity Characteristic Leaching Procedure) EPA 1311 :Method Summary. This procedure is designed to determine the mobility of both organic and inorganic species present in waste materials. The procedure provides for the shake extraction of a weighed portion of solid sample under specified conditions of time and extraction media. The filtrate is analyzed for soluble species.
Mercury SM3112B: Method Summary. The mercury in an aqueous sample is reduced to vaporous elemental mercury and is determined by cold vapor atomic absorption or by cold vapor atomic fluorescence (if better detection limits are required).
