Many health care facilities (HCF) in developing countries lack access to reliable hand washing stations and safe drinking water. To address this problem, we installed portable, low-cost hand washing stations (HWS) and drinking water stations (DWS), and trained healthcare workers (HCW) on hand hygiene, safe drinking water, and patient education techniques at 200 rural HCFs lacking a reliable wat...

The federal drinking water evaluation scheme is narrowly scoped, ignoring community level social factors, which may play a role in access to safe water in First Nations. This research used t...

A number p is a safe prime if both p and (p − 1)/2 are prime. This note describes a method of generating safe primes that is considerably faster than repeatedly generating random primes q until p = 2q + 1 is also prime.

Access to a sufficient amount of safe water is taken for granted in industrialised nations. Yet, as multiple incidents of contaminated water supplies show, citizens of highly industrialised nations such as Canada may not have access to safe water—the deadly E. coli outbreak in Waterton, Ontario, being but the most visible among many.
