Hardness Carbonate Noncarbonate Split Calculator
Split actual hardness by matched alkalinity expressed as CaCO3 equivalents; no treating alkalinity as calcium concentration, individual ion speciation or titration analysis.
Description
Hardness and alkalinity can be compared when both use CaCO₃-equivalent units.
Hardness and alkalinity can be compared when both use CaCO₃-equivalent units. Alkalinity is not a direct calcium concentration.1
Enter nonnegative matched total hardness/alkalinity in mg/L as CaCO₃. Return carbonate and noncarbonate hardness plus positive alkalinity excess.
When to use Hardness Carbonate Noncarbonate Split Calculator
Use Hardness Carbonate Noncarbonate Split Calculator when you need to evaluate the supplied records under the calculation and evidence rules below. No ion speciation, titration or calcium concentration is inferred.
Prepare the observed lake or sample measurements and explicit calibration, reference values or thresholds requested. Keep depth coverage, units, dates and sampling conditions consistent.
How to use Hardness Carbonate Noncarbonate Split Calculator and understand its results
- Prepare the observed lake or sample measurements and explicit calibration, reference values or thresholds requested. Keep depth coverage, units, dates and sampling conditions consistent.
- Enter totalHardnessMgLiterAsCaCo3, alkalinityMgLiterAsCaCo3 using the field table and calculation rules, then run the tool.
- Read carbonateHardnessMgLiterAsCaCo3, noncarbonateHardnessMgLiterAsCaCo3, alkalinityBeyondHardnessMgLiterAsCaCo3. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| totalHardnessMgLiterAsCaCo3 | Total hardness mg liter as ca co3 | number | Required |
| alkalinityMgLiterAsCaCo3 | Alkalinity mg liter as ca co3 | number | Required |
Enter nonnegative matched total hardness/alkalinity in mg/L as CaCO₃. Return carbonate and noncarbonate hardness plus positive alkalinity excess.
carbonate=min(hardness,alkalinity); noncarbonate=hardness−carbonate Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| carbonateHardnessMgLiterAsCaCo3 | Carbonate hardness mg liter as ca co3 | number |
| noncarbonateHardnessMgLiterAsCaCo3 | Noncarbonate hardness mg liter as ca co3 | number |
| alkalinityBeyondHardnessMgLiterAsCaCo3 | Alkalinity beyond hardness mg liter as ca co3 | number |

}Limitations and assumptions
No ion speciation, titration or calcium concentration is inferred.
Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
Alternative or Complementary methods
Use TDS From Conductivity Calculator: Conductivity and total dissolved solids require a local calibration on a consistent temperature basis. A universal conversion factor cannot describe every ionic mixture. For a complementary task, use Conductivity Salinity Freshwater Approximation Converter: Freshwater conductivity-to-salinity conversion needs local calibration and a stated temperature normalization. Ionic composition affects the relation.
