This powerpoint presentation begins by providing study objectives: to characterize presence of contaminants of emerging concern
(CECs) including pharmaceutically active compounds (PhACs),
endocrine disruptor chemicals (EDCs) and synthetic organic
compounds (SOCs) in Lake Erie source water; to gain understanding of the impact of Kettle Creek Watershed on
the Elgin Area Water Supply System with respect to CECs; and,
to develop an approach to determining the treatment efficacy using
bench and pilot methods for the Elgin Area and West Elgin Water
Treatment Plants. A brief overview of the City of London - Elgin Area Water Supply System is presented, along with the study approach in three phases: Phase I - identification of emerging
contaminants of concern; Phase II - determining current laboratory
capabilities and associated cost, and preliminary testing for identified
ECCs in source water; and, Phase III - determination of treatment
efficacy. Presentation summary includes: no regulated compounds detected above acceptable
concentration level;
no pharmaceuticals or EDCs were detected above
MDLs in first round of sampling at EAWSS or WEWTP
by ALS Laboratories (MDL range: 20 to 100 ng/L),
low levels of atrazine were detected in Lake Erie and low
levels of NDMA were detected in Kettle Creek; and,
the second round of testing detected very low levels of
metformin, caffeine, carbamazepine, erythromycin and
sulfamethoxazole and several EDCs in Lake Erie. Includes figures.
