Project Description

This analysis summarizes the containment, wastewater, and greenhouse gas data collected over five months of fieldwork:

  • Southern Coastal British Columbia (Canada): April-June 2023

  • Kampala (Uganda): January-February 2024

The data includes:

  1. Containment Characteristics: Household + Commercial establishment usage, operation, maintenance, demographic, technical and environmental data; collected from administered surveys (Ethical Approval Reference: 22-047 (University of Victoria, BC, Canada) & SIR275ES (Ugandan National Council of Science and Technology).

  2. Wastewater Characteristics: Physical, chemical and biological parameter data for each containment, collected at depths (Top, middle and bottom) of entire containment contents.

  3. Greenhouse Gas (GHG) data: Linearly extrapolated mass emission rates from point-source measurements taken from a floating modified flux chamber over a period of 30 mins.

Data

Data Packages

The data analysis and visualization were performed using R version 4.4.1 (R Core Team, 2023). We utilized several R packages for data manipulation, statistical analysis, and visualization:

The tidyverse ver 2.0.0 suite of packages (Wickham et al., 2019), which includes ggplot2 for data visualization, dplyr for data manipulation, and tidyr for data tidying.

Data Import & Setup

This analysis uses the fecalcanuga package, which contains raw data from this five-month field study: Southern Coastal BC (Canada): April–June 2023; Kampala (Uganda): January–February 2024 on non-sewered sanitation containments across a total of 41 sites. It also imports a specific dataset, ghg_emissions_edited.xlsx, for detailed GHG emissions analysis.

A description of the three data sets: containment, household_survey, phys_chem_parameter, including an overview of the variable names and their respective units can be found at: https://github.com/kelseyshaw/fecalcanuga.

Data Cleaning & Validation

Excluded:

  • Two sites from Southern Coastal BC, Canada (pre-packaged aerobic units, out of scope).

  • Accumulation rate (high variability and uncertainty).

Missing Values

The percentage of missing values for each parameter, excluding some survey-related questions that are user-dependent and in the cases below answered as “I don’t know”, is below 5%, which is acceptable. The only exception is for Biochemical Oxygen Demand (BOD), which has an 11.5% missing rate due to equipment constraints, as not all samples could undergo BOD analysis, however it is still representative of the data set.

Analysis

Containment Characteristics (Questionnaire Data)

This section organizes and summarizes the containment characteristics for each sampling location that were collected as either a part of the administered questionnaire or physically measured on site (i.e., containment volume, wastewater depth, etc.). Each sample is assigned an ID and a country based on the collection date. It is also important to note that each containment was classified as household or commercial for establishment_type.

Sampling Overview

The dataset includes samples collected from different regions and categories, as follows:

  • Canada - Commercial: 4 samples from establishments including a restaurant, community hall, library, and golf course, in Southern Coastal BC.

  • Canada - Household: 16 samples from single-family homes, in Southern Coastal BC.

  • Uganda - Commercial: 2 samples from hotels, in Kampala Uganda .

  • Uganda - Household: 17 samples from multi-family homes and apartments, in Kampala Uganda.

This section visualizes the distribution of the numeric variables from Table S5 and Table S6 across all samples, separated by geographical location and establishment type.

Statistical Testing

This section evaluates whether numeric and non-numeric parameters collected on-site and through the questionnaire differ significantly between:

  • Southern Coastal BC and Kampala; and

  • Household and. Commercial establishments.

  1. Numeric Parameters:

    • Normality was assessed using the Shapiro-Wilk test for both groups.

    • If both groups were normally distributed, a t-test was used to compare means.

    • If one or both groups were not normally distributed, a Wilcoxon test was used to compare medians.

    • Results indicate if differences are statistically significant (p < 0.05).

  2. Non-Numeric Parameters (Logical/Factor):

    • Proportions are compared using:

      • Fisher’s Exact test for smaller expected counts.

    • Results indicate if distributions differ significantly between groups.

In the comparison between Southern Coastal BC and Kampala, 18 parameters of 35 total showed statistically significant differences, including 6 of 9 total numeric and 12 of 26 total non-numeric parameters. For Household vs. Commercial, only 4 parameters showed statistically significant differences, they were laundry, wastewater_type, last_emptied, users.

Multivariate Analysis

To complement univariate tests and account for parameter correlations, multivariate multiple regression (MMR; Pillai’s trace = 0.759, approx. F = 7.329, df = 9,21, p < 0.001) tested region (Southern Coastal BC vs. Kampala) as predictor of the multivariate response (10 scaled numeric parameters). Analyses used car and stats packages in R v4.4.1.​

Additionally, PERMANOVA (adonis2, vegan; R² = 0.123, F = 5.203, p = 0.001, 999 permutations) on Euclidean distances confirmed non-parametric multivariate differences by region, with dispersion homogeneity verified (betadisper, F = 0.863, p = 0.686).

While univariate analyses identified numerous parameters differing by country, these multivariate tests demonstrated that country remained a highly significant predictor of the numeric parameter set as a whole (explaining up to 76% multivariate variation via Pillai), accounting for correlations among parameters.

Wastewater Characteristics

This section organizes and summarizes the physico-chemical and biological data of wastewater samples collected in situ and from laboratory analysis. Each sample is assigned an ID and a country based on the collection date, and summary tables are generated for each unique combination of sample ID and sampling depth (T, M, B): Top, Middle, Bottom. Averages are also calculated for each ID across all depths, to represent composite samples for each containment.

Statistical Testing

Description: This section evaluates whether numeric wastewater data collected in situ and from the lab differ significantly between various groupings:

  1. Regional Comparison: Southern Coastal BC vs. Kampala.

  2. Establishment Type: Household vs. Commercial.

  3. Sampling Depth Levels: Top (T), Middle (M), and Bottom (B).

For each comparison:

  • The Shapiro-Wilk Test checks whether the data for each parameter are normally distributed within each group.

  • Based on normality results:

    • t-test is used if both groups are normally distributed.

    • Wilcoxon test is used if one or both groups are non-normally distributed.

  • However since almost all parameters were non-normally distributed, except for pH which is already log transformed and vs_percent, non-paramteric tests could be used on all for consistency. The results indicate whether differences are statistically significant (p < 0.05) and include a summary of normality for the groups. It should be noted that for both pH and vs_percent statistical results had the same outcome with parametric and non-parametric tests.

Spearman Rank Correlations: Containment & Wastewater Data

Spearman rank correlation analysis was completed given the majority of parameters were non-normally distributed. This was combined with p-values (<0.05) to see if strong correlations were statistically significant or not. Completed for each region separately, given the majority of containment and wastewater parameters showed statistically significant differences. Household establishments were the focus of this analysis so that is what was calculated for and shown here.

This section outlines the analysis framework used to calculate emissions from the NSS containments, focusing on 1) per capita and population equivalents (PE), 2) per containment surface area and 3) cumulative over time (ppm).

Emissions Calculations

In order to determine the flux of methane from the point-source samples over the 30 min sampling period a linear model needed to be fit for each containment’s data set to extract the slope.

The three instances of zero methane do not indicate anomalous measurements but reflect the specific conditions at the time of sampling. Their inclusion in the dataset ensures transparency, while their exclusion from further methane calculations avoids bias in the household-focused analysis.

Specifically, two of these cases were in Canada: one from a commercial/library establishment (not included in household analyses) and one from a household. The third was from a commercial establishment in Uganda. In all three cases, the containments had been very recently emptied, which may have influenced the absence of detectable methane.

The following figures demonstrate this linear fit.

Using the linear fit model cumulative emissions for each containment sampled could be calculated (Methane, Carbon Dioxide and Nitrous Oxide)

CH₄ was the primary focus due to its significant climate impact. CO₂ was excluded, however there were linear trends between CH₄ and CO₂ that mean they are comparable for this study, and N₂O was excluded due to non-detectable emissions across all sampled containments.

Population Equivalents

Two scenarios to estimate Population Equivalents (PE) for greenhouse gas emissions data. These scenarios incorporate adjustments that account for the amount of time individuals spend at home:

  1. Standard Method (Option 1): A baseline calculation where 1 PE equals the number of users for household establishments.

  2. Time-adjusted Method (Option 2): Adjusts the calculation such that 1 PE equals the number of users multiplied by 0.7 for household (Southern Coastal BC) and 0.3 for households (Kampala, Uganda).

Central Tendancy Calculations

This section explores robust measures of central tendency to summarize GHG emissions data across different categories and options while mitigating the impact of outliers. From this analysis it was determined that the median is the most representative. The following metrics were calculated to verify:

  1. Trimmed Mean: Mean calculated after removing the lowest and highest 10% of values.

  2. Interquartile Mean (IQR Mean): Mean of values between the 25th and 75th percentiles.

  3. Geometric Mean: A multiplicative average, less sensitive to large outliers.

  4. KDE Mode: The peak of the probability density curve, representing the most common value.

Methane Correction Factor (MCF)

This table presents the Methane Correction Factor (MCF) calculations for the median values derived from Population Equivalent Emission rates: Option 1 and Option 2. The steps include:

  1. Field Emission Rate: The Median values ( g/cap-d ) are converted to ( kg/cap-d).
  2. Emission Factor (EF): The field emission rate is divided by the BOD loading rate (( L = 0.06 (Canada) , kgBOD/capita/day ) and 0.037 (Uganda)). * IPCC 2019 Refinement Values Table 6.4
  3. Methane Correction Factor (MCF): The MCF is computed using the maximum CH4 production capacity (B_0 = 0.6 , kgCH_4/kgBOD ). * IPCC 2019 Refinement Values
