The pollution problem arising from the flushing of initial rainwater and wastewater from accidents while transporting dangerous goods to source water protection areas needs to be solved as soon as possible. Therefore, the design of corresponding environmental protection measures should be considered in the engineering design stage. It is necessary to analyze the specific work in combination with engineering examples. Under this background, this paper first briefly expounds the precautions in accident risk analysis and the design of tank capacity and tank body. Finally, by analyzing actual cases, this paper systematically studies the design strategy of emergency pool in source water protection area, hoping to provide new development ideas for the upgrading of relevant work.

Payments for watershed services (PWS) programs are becoming a popular governance approach in the western United States (US) to fund forest management aimed at source water protection. In this paper we conduct a cost-benefit analysis (CBA) of one of the first collaboratively funded PWS programs in the US, located in the municipal watersheds servicing Denver, Colorado. We combine wildfire modeling, sediment modeling, and primary and secondary data on economic values to quantify the impact of the program on protecting multiple values at risk. Our results show that while the program has led to diverse societal benefits, it is only economically efficient (benefit-cost ratio greater than one) when all co-benefits beyond source water protection are considered and fuels treatments are assumed to encounter wildfire. When the probability of wildfire is accounted for, economic benefits would need to be triple what was estimated in our analysis to achieve economic efficiency. Our findings suggest that improving spatial prioritization of interventions would increase economic benefits and better data on treatment placement and costs would help facilitate future CBA of PWS programs focused on wildfire mitigation.

The purpose of this research was: 1. to investigate whether the perception of drinking water-related risk differs between the public and a Source Protection Committee established under Ontario's new Clean Water Act to make decisions about source water protection, 2. to explore how the public makes risk-based decisions about drinking water-related risk, and, 3. to estimate how any differences in drinking water-related risk perception and decision making between the Committee and the public may affect the implementation of the Clean Water Act. Mail and telephone surveys were conducted in a Southern Ontario Region of Study, and were given to samples of the public and the Committee. The two groups had different perceptions of water risk, which could pose challenges for making collective decisions about water risks. Successful source water protection depends on the ability of the Committees and the public to make appropriate decisions about risks to drinking water sources.

Historically an unequal distribution of capacity existed among local Municipalities and Conservation Authorities with regards to protecting water in Ontario, as well there was no specific legislation pertaining solely to source water protection. The aim of this research project is to present and analyze through a comparative assessment, the financial capacity requirements and the technical, institutional, social and political capacity progress observed among the 19 Source Protection Regions across Ontario in terms of protecting source water following the Walkerton event and the enactment of the Clean Water Act (CWA). The results indicate that through the enactment of the CWA, capacity building initiatives have taken place through a top-down model with the provincial governments' guidance, direction and support to local municipalities and CAs. When the provincial government takes control and provides capacity related assistance, the lower level municipal and CA governments become regulated; functioning more effectively and with a level of consistency across the province.

First Nations in Canada are disproportionately affected by chronic drinking water insecurity (Bakker, 2012). Aboriginal Affair and Northern Development Canada conducted an assessment of First Nations water and wastewater systems in 2001 and found significant risk to the quality and safety of drinking water on three- quarters of all systems (Johns and Rasmussen, 2008). Neegan Burnside (2011) classified four differentrisks that affect drinking water systems for First Nations, which include, no source water protection plan,deterioration of water quality over time, risk of contamination, and insufficient capacity to meet futurerequirements. This study found that the two highest risks were risk of source water contamination and thelack of a community source water protection plan (Neegan Burnside, 2011). Water security, sustainableaccess on a watershed basis to adequate quantities of water of acceptable quality to ensure human andecosystem health (Bakker, 2012), therefore requires source water protection and collaboration amongwater actors. Collaboration is defined as the pooling of resources by multiple stakeholders to solveproblems, which includes a balance of power among actors, mutually agreed upon objectives, is perceived as legitimate, and includes a wide variety of stakeholders (Ashlie, 2019; Van Der Porten, 2013; Spencer etal., 2016; Black & McBean, 2017).
