Monarch Hill uses a synthetic double-liner system to protect groundwater and a sophisticated system to collect the liquid or “garbage juice” (called leachate) that is created by rainfall or liquids in the decomposing waste.
The liner system consists of six layers including two layers of 60-mil high-density polyethylene (HDPE) liner, two layers of synthetic geo-textile and two layers of a synthetic geo-net.
The leachate collection system transports the leachate, which can total nearly three million gallons per month, to the Broward County Water and Wastewater Services facility through a dedicated force main. The leachate is treated and released into the system as reclaimed water.
Groundwater from 43 groundwater wells is sampled and analyzed twice a year to monitor water quality by outside regulatory agencies. Retention ponds have also been constructed around the site to contain storm water runoff, and the water in these ponds is sampled twice a year to assess its quality.

WM team members work to protect the environment, minimize litter, and tend to the aesthetics of the site. Crews routinely clean the streets and pick up windblown litter around the property.Monarch Hill’s wildlife specialist, trained by the U.S.Department of Agriculture Wildlife Service, manages the bird population on-site to keep populations down and minimize impacts to the community.
