Arguments

data: Tibble containing wastewater facility metadata.
wastewater_type_col: Column storing the wastewater classification.
eligible_types: Wastewater types that fall within the AMS-III.H scope.
cod_concentration_col: Column storing influent COD concentration in mg/L.
minimum_cod_mg_l: Minimum COD concentration required for applicability.
anaerobic_fraction_col: Column storing the fraction of flow to anaerobic treatment.
minimum_anaerobic_fraction: Minimum anaerobic fraction required for applicability.
baseline_system_col: Column describing the baseline treatment system.
excluded_baseline_systems: Baseline systems that already capture or destroy methane.
group_cols: Optional character vector specifying grouping columns.
output_col: Name of the logical output column summarising compliance.

Value

Tibble summarising whether each grouping combination meets wastewater requirements.
