Getting Hepatitis A Off the Streets of San Diego
By Ralph Morris, M.D., M.P.H.

Hepatitis AA Hepatitis A outbreak centered on homeless and illicit drug-using populations in the County of San Diego, California, has prompted a public health emergency. Headline-grabbing responses by local officials describe washing the streets and sidewalks with chlorine bleach solution, aggressively vaccinating the vulnerable populations, and distributing personal hygiene kits. What caused this local outbreak and can these measures help mitigate it?

The Facts about Hepatitis A

Hepatitis A is a highly contagious viral disease that affects the human liver, according to the US Centers for Disease Control and Prevention (CDC). It is usually spread through the fecal-to-oral route, either by person-to-person contact or by consuming contaminated food or water.

Before the era of drinking water chlorination, over a century ago, Hepatitis A, along with typhoid fever and cholera, was one of the great waterborne scourges of American life. Today chlorine-based disinfectants are routinely used during water treatment to destroy the … READ MORE >>

In the Wake of Hurricanes: The Problem with Standing Water
By Fred M. Reiff, PE

A discarded tire containing standing water can become a choice breeding ground for mosquitoes.

A discarded tire containing standing water can become a choice breeding ground for mosquitoes.

As flood waters recede in Houston and Florida, a new public health threat rears its ugly head: Mosquitoes breeding in standing water left in the wake of hurricanes. Puddles, flower pots and saucers, rain barrels, bird baths, pet bowls, discarded tires, overturned trash can lids, canvas and plastic tarps covering boats and pools, and even swimming pools themselves can become watery incubators for mosquitoes.

Although most mosquitoes do not spread disease, some do spread Zika virus, West Nile virus, chikungunya, malaria, encephalitis and dengue fever. Fortunately, after a quiet summer for Zika virus on the US mainland during which there was no known local transmission of the virus, the US Centers for Disease Control and Prevention (CDC) does not expect to see cases of Zika virus appearing in the wake of flooding from the recent hurricanes, READ MORE >>

Striving for a better world by 2030, countries around the globe are beginning to incorporate the new, ambitious UN Sustainable Development Goals into their national agendas. Among the 17 bold goals, which include ending poverty and hunger, is the goal of universal access to safe drinking water and sanitation. This goal was front and center at last week’s Stockholm International Water Institute’s (SIWI) World Water Week meeting, the world’s biggest annual global meeting focused on water and development. SIWI Executive Director, Torgny Holmgren noted, “… it is here that we come together and make sure that the very best ideas are brought forward”.

One of those ideas originated with two Long Island, New York, high … READ MORE >>

By the Water Quality & Health Council

Houston residents walk across a flooded street on August 27, 2017. Hurricane Harvey dumped trillions of gallons of water in several Gulf states, leading to devastating flooding.

Houston residents walk across a flooded street on August 27, 2017. Hurricane Harvey dumped trillions of gallons of water in several Gulf states, leading to devastating flooding.

After the shock and heartbreak of experiencing a flood comes the clean up to prevent further damage and spread of disease. Flood cleanup starts with removing flood water (usually contaminated with sewage) and drying the affected areas. Evaluate all items touched by flood waters, deciding which to keep and which to toss. Whenever possible, use a disinfecting solution of chlorine bleach to disinfect items touched by flood waters.

  • When using a disinfecting solution to clean up after a flood, remember to:
    • Wear gloves and protective clothing. Do not touch your face or eyes.
    • Change the disinfecting solution often and whenever it is cloudy.
    • Be thorough. Wash and dry everything well.
    • When finished, wash your hands thoroughly with soap and water for at least

Touring Orange County’s Groundwater Replenishment System and Celebrating World Water Week 2017
By the Water Quality & Health Council

gwrsThe theme of this year’s World Water Week, which runs from August 27 to September 1, is “Water and Waste: Reduce and Reuse.” World Water Week was established in 1991 and is organized each year by the Stockholm International Water Institute (SIWI).

To mark World Water Week, we thought it only fitting to share a highlight of our July 2017 summer meeting—a tour of the unique Groundwater Replenishment System (GWRS) of the Orange County Water District and the Orange County Sanitation District (OCWD/OCSD) in California.

World Water Week 2017

SIWI promotes sustainable development in water governance and transboundary water management. In 2016, SIWI named WQ&HC’s Dr. Joan Rose winner of their prestigious Stockholm Water Prize. As described in their program, World Water Week 2017 will focus on United Nations Sustainable Development Goals 6 (Clean Water and Sanitation) and 12 (Responsible Consumption and Production).
