This powerpoint presentation begins by providing a brief overview of the Lead and Copper Rule, the St. Paul Water Resource Services, stannous chloride, and microbially influenced corrosion. Study objectives included: Sn may reduce Pb release by reducing
the rate of microbially-influenced
corrosion; and,
toxicity to biofilm bacteria. The
hypothesis was that Sn inhibits biofilm growth. The effect of stannous chloride on lead
corrosion and on the
development of biofilm are both presented. Presentation conclusions indicate the following:
stannous chloride does not appear to
effect lead surface potential;
it does not appear to affect lead surface
mineralogy;
it reduces the development of biofilm at
doses as low as 0.125 mg/L Sn<sup>2+</sup>; and,
it causes reduction of developed biofilm
at approximately 1 mg/L as Sn<sup>2+</sup>. Includes 6 references, figures.
