         The Problem

                                                                Quarry lakes are known to carry dead animals causing

       as swimming pools.
       Summer is the time when people are the most tempted
       to dive into the water and go to the nearest pool or lake.
       People often disregard the warning signs and cross over
       the gates and damaged fences. Most quarries can not
       be drained in the water supply as the water is too toxic.
       Some quarries are filled with beautiful blue, tropical
       seeming water, which actually happens due to the
       leaking of calcite crystals into the waters as a result of
       quarrying activity.
       Such lakes may look inviting but the perils remain same
