Determine if TOC removal meets Stage 1 DBP Rule requirements

Source: R/regulate_toc.R
regulate_toc.Rd

This function takes raw water alkalinity, raw water TOC, and finished water TOC. It then calculates the TOC removal percentage and checks compliance with the Stage 1 DBP Rule.

Usage

regulate_toc(alk_raw, toc_raw, toc_finished)

regulate_toc_df(
  df,
  alk_raw = "use_col",
  toc_raw = "use_col",
  toc_finished = "use_col"
)

Arguments

alk_raw

Raw water alkalinity (mg/L as calcium carbonate).

toc_raw

Raw water total organic carbon (mg/L).

toc_finished

Finished water total organic carbon (mg/L).

df

a data frame optionally containing columns for raw water alkalinity, raw water TOC, and finished water TOC

Value

A data frame containing the TOC removal compliance status.

A data frame with compliance status, removal percent, and optional note columns.

Details

The function prints the input parameters and the calculated removal percentage for TOC. It checks compliance with regulations considering the raw TOC, alkalinity, and removal percentage. If the conditions are met, it prints "In compliance"; otherwise, it prints "Not in compliance" and stops execution with an error message.

Examples

regulate_toc(50, 5, 2)
#>   toc_compliance_status toc_removal_percent
#> 1         In Compliance                  60
