For Living Waters for the World, the mission is clean drinking water
In Tabasco, Mexico, water is left undrinkable by mineral deposits in soil and a coastal aquifer that runs beneath the Yucatan Peninsula. Many communities can’t treat it and depend on trucks to bring in drinking water. 
 
But for one small community there, a mission group helped reduce its dependence on outside water by setting up and donating a custom water filtration system. A church houses the system and gives treated water to those who can’t afford it at no cost. The water is otherwise sold commercially at half the price offered by other bottlers. 
 
Living Waters for the World is a mission project of the Presbyterian Church - USA and is no stranger to water treatment projects.

The Lufft WS800 Multi-Parameter Weather Station measures a full suite of atmospheric parameters that provides all-encompassing data on the local environment, including a one-of-a-kind lightning detector. This compact, cost-effective sensor simultaneously measures air temperature, humidity, pressure, precipitation, solar radiation, lightning, and wind with an integrated electronic compass. An internal fan and heater reduce the effects of external influences for accurate measurements during long-term deployments. The sensor can be easily mounted on a 2-inch diameter pipe above any local obstructions with the included bracket mount, U-bolts, and 10-meter cable. 
 
 Settings for the unit can be adjusted using the latest UMB-ConfigTool.

Monitoring Newfound Lake's tributaries allows the NLRA to better understand how these systems are changing and helps to quantify the impact that development is having on water quality in Newfound Lake. (Credit: NLRA) 
As many resource managers and conservation groups can attest, their work serves both the environment and the surrounding communities. Dynamic and healthy ecosystems can become center points for towns, cities, and entire regions—such is the case in the Newfound Lake Region, located in central New Hampshire. The Newfound Lake Region Association (NLRA) knows just how critical the preservation of the lake and surrounding watershed is for all members of the region.
