john 12:35-36 In 2007, the Laguna Lake Development Authority (LLDA) reported that Laguna Lake was in danger of dying in five years if no steps were taken to clean it up (Greenpeace). The five years elapsed in 2012, and no substantial steps have been taken to this day.
In April, 2016, a ‘manganese surge’ reached the homes of 1.2 million consumers due to the El Nino drought which lowered lake water level dramatically. Manganism or manganese poisoning, a heavy metal, involves permanent neurological disorder with symptons of tremors, facial muscle spasms, irritability, aggressiveness, and hallucinations.
Water sampling done too late weeks after the surge revealed manganese dissolved in water was within safe limits. But how about future droughts and surges? No tests were done on manganese silt or solid particles. Consumer advocate Pete Ilagan of NASECORE sent a letter to Maynilad to answer critical questions. There was no reply.
From the start, Maynilad failed to consider that Laguna Lake is an environmental time bomb, in sourcing household water from it. Perhaps it was too eager about the fantastic idea of an easy cheap source of voluminous water so close to Metro-Manila. Or perhaps it was so confident that its P1.4 billion high-tech water treatment plant at Putatan, which Noynoy inaugurated so proudly in 2011, could handle any kind of pollution.
Its sophisticated microfiltration failed to filter manganese on a massive scale. A water sampling expert said it could have been a management failure to change clogged filters during the surge. Today, Maynilad gets big profits supplying a staggering 100 million liters of water a day to 1.2 million consumers.
LLDA conferred on Maynilad a Blue Award for its Putatan Water Treatment Plant in May 2014. In April 2016, the plant failed to stop the ‘manganese surge’.
President Aquino undrapes the marker of the 100 million liters of water per day Putatan Water Treatment plant in February 2011, one year before the LLDA prophecied the lake would die by 2012. The LLDA prophecy of Laguna Lake dying soon is ominous. Massive rehabilitation is impossible. As population increases, both household and industrial pollution seem unstoppable. Without mitigating measures, Maynilad, perhaps should find alternative sources this early to avoid future inevitable mass poisoning, for which it may face class action suits. Manganese poisoning is nothing compared to mercury or lead poisoning.
Laguna Lake Statistics
Laguna Lake is a ticking environmental time bomb because the 220-km. lakeshore population is a staggering 15 million in 2010 (NSO). Household waste accounted for 77% of total pollution load, and industrial waste 11%. Greenpeace said LLDA reported dumpsites of Paete, Binan, Angono, and Taytay were too near the lakeshore area in December 2007. The Angono dumpsite was being used in spite of closure orders by the Mayor, Greenpeace added.
Laguna Lake has only one outlet – Manila Bay via the Pasig River, which is often clogged with water lilies that grow abundantly in the lake. Yet, it is fed by 22 major tributaries in a 45,000 sq. km. catchment area. It is a buffer for flood waters, especially from Marikina River. Not including the lake, the pollution from households and firms in this vast catchment area ending up in the lake is massive.
Within the catchment area are many export processing zones, which have semiconductor firms, a major source of pollutants. A Greenpeace report in 2007 revealed water samples from community handpumps in Guandong, China near electronic and semiconductor facilities showed “elevated levels of toxic zinc and vanadium”, and trihalomethanes, a carcinogenic. Greenpeace filed a similar report on Laguna Lake (see ‘sources’ below). Heavy metals have settled on the lake bed cumulatively through the decades, which is hard to clean up. There is little rehabilitation being done. DENR and LLDA mainly do monitoring.
The lake is only 1 meter above sea level, making gravitational outflow weak. Add the water-lily factor and the lake is relatively stagnant and flood-prone. Water levels rise quickly during rainy season and recedes quickly during droughts. Laguna Lake is oddly the largest but shallowest lake nationwide. Its average depth is a mere 2.8 meters, yet it is 911 to 949 sq. km. in area. Water quickly dries up in such a large area, exposing large areas of the shore. This is perhaps why there was a ‘manganese surge’, which Maynilad attributed to the lowering of water level due to the El Nino. Maynilad admitted the manganese surge when they issued a warning to consumers to put a cloth filter on their tap to catch manganese silt. Silt can settle in home water tanks, and sip into the underground water table when you water your garden. If there are 100 million liters a day for 1.2 million consumers, this is quite a big impact.
On top of the silt problem is manganese dissolved in water, which goes into food if used to wash rice or vegetables or for coffee or soup. So consumers, be warned. The yellowish tint of cloth filter persisted for a few more weeks. Deadly solid particulates should never enter the household water system.
The DENR needs to conduct an investigation, gather past historical sampling tests, and recommend whether Maynilad should continue to tap Laguna Lake water. A massive LGU campaign against dumpsites and household wastes is also urgent. LLDA should start using the environment fees it exacts from firms for the environment. If we stop sourcing Laguna Lake, we may have a water crisis. If we continue, we may have a poison crisis. Without any action, we may be headed for an environmental tsunami.
