<br />An initial assessment will be performed to evaluate the existing condition of the water well. Based on the initial
<br />evaluations, rehabilitation options will be proposed. The entire well will have to pulled and the casing will have to
<br />be video inspected. Common causes of reduced well capacity could be sanding, rupture of Casing, mineral build-
