Universal WASH Gains Traction Even as Hand Pumps Lose Ground

Well over 1 billion people have gained access to clean water since India Mark II and Afridev hand water pumps went into widespread operation in the 1980s. That's success. But they are ticklish to manage. According to various studies, between 25 percent to 40 percent of the installed pumps no longer work due to weak community maintenance programs, corrosion, failed parts, and poor well construction.
Because of that, the Mark II and Afridev pumps are stirring another dispute: Could the "death of the hand pump," as the Dutch think tank IRC suggests, be at hand?

California Tribes Call Out Degradation of Clear Lake

Clear Lake, about 100 miles north of San Francisco, is relatively shallow, warm and, by its nature, biologically productive. That’s why it’s known as one of the best bass fishing spots in the country. It’s also considered the oldest lake in North America, which means that algae have probably been present for some portion of its 2 million years. Indigenous groups have lived along the lake’s clean waters and fertile shores for some 12,000 years.

But over the last century and a half, Clear Lake’s ecological balance has come undone. White settlers planted orchards, dug mercury mines, and built homes and towns. In the process an estimated 85 percent of the lake’s nutrient-absorbing wetlands were destroyed. Unimpeded flows of nitrogen and phosphorus tipped Clear Lake into hyperproductivity, or eutrophication. Algae and cyanobacteria blooms worsened in the 1970s, starting improving through the 1990s, and now are as extensive as any in generations.

Toxic Cyanobacteria Choke Water Systems Around California’s Clear Lake

Not only an aesthetic affront, harmful algal blooms in California’s Clear Lake are a threat to public health, recreation, and the local economy. For the 18 public water systems that draw from the lake the noxious blooms are something else: an operating hazard that is complicating their treatment processes and increasing the cost of providing clean water in one of the state’s poorest counties.

The degradation of Clear Lake and the steps water managers are taking to deal with it, are a distillation of the turmoil that algae and cyanobacteria are taking across the United States and around the world. Reducing the threat is expensive. State and federal water quality regulators, prodded by deteriorating conditions at Clear Lake and in other areas, are taking notice.

Chemical Impact: Microplastic Pollution More Complex Than We Think, Says New Research

Microplastic pollution has been building up in the Great Lakes for at least four decades, but our understanding of its impact on fish and other aquatic creatures is only just catching up.

Now new research from the University of Toronto shows the harm to wildlife is due to a wide range of factors that is not generally considered in toxicology testing – the plastics’ size, shape and chemical makeup.

In particular, it shows larval fathead minnows exposed to microplastics collected from Lake Ontario developed almost six times more deformities compared to when they were exposed ‘pristine’ pre-consumer microplastics. This suggests microplastics in the lake soak up contaminants in the water and that it is these chemicals that are causing deformities.

HotSpots H2O: In Mali, Climate Change Disrupts Peace Efforts

Climate change, environmental insecurity, and limited fresh water are escalating conflict throughout Mali, preventing peace-building and disrupting livelihoods, according to a report published by the Stockholm International Peace Research Institute (SIPRI) last month.

For over a decade, the people of the West African country have endured government conflict and attacks by terrorist fundamentalist groups. Now, after years of destabilization and weak governance, Mali’s changing climate has undermined attempts for peace and further challenged people who are dependent on the country’s resources and environment.

Durban Water and Sanitation For Poor Sets Global Standard

Arguably the most elegant aspect of an inelegant subject is how Durban, South Africa’s second largest city with 3.2 million residents, is solving monumental water and waste challenges in its jammed informal settlements.

The eThekwini (ett-ta-kweeny) Muncipality Water and Sanitation Department, Durban’s water and waste management provider, avoided huge and expensive equipment, big pipelines, and the complicated sewage disposal practices of centralized water and sanitation systems. Instead it deployed a decentralized strategy, partnerships, baseline research, and less expensive tools that worked.

The centerpiece of Durban’s program for the time being is the “community ablution block” public washroom. It is an ordinary marine cargo container refitted inside with running water in sinks and wash basins, toilets and showers. Durban has 2,500 ablution blocks installed in many of its nearly 500 informal settlements. There is sufficient public funding to fabricate and install perhaps 80 more annually.
