Based on our discussion yesterday, I see a strong need for a health based standard not on water quality, but how water quality impacts people medically. The lead and copper rule (LCR) standard is necessary for water utilities to measure the content of water coming out of their plant and potentially through the distribution system. More discussion needs to happen around who is responsible for the water distribution once it leaves the plant. Every city is different and every city has citizens with different opinions on who bears the burden and the cost for pipe replacement. So how can we prevent lead poisoning of people through the water supply? What would be an effective health based standard that citizens impacted by the risk and those responsible for resourcing the fix, agree to. Blood lead levels (BLL) does not seem like a good metric to resolve this problem. As Dr. Simoni Triantafyllidou noted, BLL is contingent on so many different variables. How can governments or their contracted utilities agree to a standard with so many variables out of their control? Is it the governments’ responsibility in total to provide clean water with zero medical impacts? How would any institution be able to agree to that standard? How would a city or state budget for medical impacts on people? Where does the responsibility manifest today and what has resulted? I think we can see that the attempt or assumption of putting responsibility for medical impacts upon the government creates an environment where “risk” studies do not identify risk.
How can we bring those responsible for governing and those governed together in shared responsibility? I don’t think this idea can even be discussed in an honest and open way, unless the conversation can take place with full transparency without retribution. Science could be the mechanism where this takes place. A shared responsibility for science: data collection, research question development, monitoring, testing, loosening of definitive causality requirements for resourcing, analysis of risk – may create an environment where understanding of the science (trust of the information) becomes owned by all impacted. Could effective decisions on avoiding or mitigating risk and resourcing against that risk be prioritized or even accomplished if government and citizens through the shared mechanism of science, shared the responsibility for identifying and mitigating risks to include lead in drinking water?
