The development of Guidelines for Canadian Drinking Water Quality is described. These guidelines are compared with guidelines published by the World Health Organization in 1984. Information is included on drinking water quality in Canada and drinking water consumption habits of Canadians. 

Levels for most metals and organics are well below the maximum acceptable concentrations (MAC) specified in Guidelines for the Canadian Drinking Water Quality (1978). However, the highest level of lead found in some localities is higher (79.7 /xg/L) than the MAC (50 Mg/L). 

The 1978 Guidelines for Canadian Drinking Water Quality included phenols (for organoleptic reasons), biocides, and THMs. Nitrilotriacetic acid (NTA) was included because of its use as a constituent ofdaundry detergents, most of which are disposed into surface waters. Studies with rodents have shown that very large doses of NTA can result in an increased incidence of urinary tract tumors. THMs were included because of their production during the process of chlorine disinfection.

The Guidelines for Canadian Drinking Water Quality, published by Health Canada, state a Maximum Allowable Concentration of 0.010 mg/1 (10 pg/1) and is based on a sample taken after flushing. The Guideline was developed in 1992 and subsequently implemented by the provinces and territories and remains the health-based lead limit for drinking water in Canada.
