Evaluation of the daycare mangers’ knowledge, attitude, and practice on lead in drinking water at daycares licensed by the Fraser Health Authority
Background: Daycares in BC fall under the Community Care and Assisted Living Act which require all daycare facilities to provide a safe environment, including drinking water. Young children who have been exposed to lead in drinking water at schools and daycares can incur serious health effects, including damage to cognitive development. Previous research has demonstrated that even low levels of blood lead concentration are associated with intellectual disability, slowed growth and development, lowered ability to concentrate, decreased academic achievement and behavioural problems. Individuals’ knowledge, attitude and practice (KAP) on drinking water can influence on how the children consume drinking water and potentially cause adverse health effects. This study evaluated daycare managers’ knowledge, attitude, and practice (KAP) on lead in drinking water related to this issue. Method: This study was conducted by collecting 106 responses from a KAP survey to evaluate the knowledge, attitude, and practices regarding drinking water contaminants. The survey was distributed to daycare managers in Fraser Health region. The responses were analyzed with regression and correlation, one-way ANOVA, and chi-square tests. Results: There was a statistically significant correlation between the age of daycare manger and their knowledge (t-test = 0.0309). All other tests showed no statistical correlation, difference, and/or association (p-value greater than significance level of 0.05 on all parameters) between managerial experiences, age of managers, types of daycares in their knowledge, attitude, and practice regarding lead in drinking water in daycare facilities. The data of KAP questionnaires indicated that most daycare mangers do not fully understand and not are sufficiently educated regarding lead toxicity in drinking water. Conclusions: The results of KAP surveys showed that an educational intervention by the government or local health authorities is highly recommended and needed to improve the daycare managers’ knowledge, attitude, and practice regarding lead in drinking water. Additional research is required to confirm this., Peer-reviewed article, Published., Project submitted in partial fulfillment of the requirement for the degree of Bachelor of Technology in Environmental Health, British Columbia Institute of Technology, 2017., Peer reviewed, Lead, Water contaminants, Drinking water, Daycares, Knowledge, Attitude, Practice, Perception
Heterotrophic bacteria in botte refill stations
Background: Heterotrophic bacteria are commonly found in water supplies where there is inadequate or non-existent disinfection. Water coolers are known to have high HPC levels due to the filtered, non-chlorinated water provided. Water bottle refill stations utilize a carbon filter which can act as a food source for HPC. This study measured HPC levels in water samples from bottle refill stations to determine whether there is a difference compared to tap water at BCIT. Method: Standard Method 9060 A was used to collect water from bottle refill stations to compare to non-filtered tap water. Samples were plated using R2A Agar and incubated for 7 days before enumerating HPC from water samples. Samples were collected from specific drinking water fountains that contained Carbon Filters and compared to the nearest tap water source. Results: Mean HPC levels in bottle refill stations were found at 95 cfu/mL while mean HPC levels in tap water were 55 cfu/mL. A two-sample T-test confirmed that the mean HPC levels of bottle refill stations and tap water are statistically significantly different (P= 0.000124). Although the findings were statistically significant, the study’s power was low at 11%. Conclusion: Based on the results, drinking water obtained from bottle-refill stations at BCIT contained on an average higher level of HPC compared to tap water. Overall, HPC levels were below recommended levels in drinking water and not considered to have any harmful effects. To continue the safe use of bottle refill stations, facilities should develop and follow written procedures to maintain stations and ensure regular changing of filters., Peer-reviewed article, Published., Project submitted in partial fulfillment of the requirement for the degree of Bachelor of Technology in Environmental Health, British Columbia Institute of Technology, 2017., Peer reviewed, Heterotrophic, HPC, Carbon filter, Drinking water
