Storm Lake water supply could be in trouble in drought's wake

Wednesday, December 12, 2012

During a special Thursday meeting, Storm Lake City Council members approved investigating eight sites for potential new water supplies.

Due to a combination of complex conditions, including drought and age, Water Resource Manager Doug Rainforth told council members he was concerned the city's current wells may not be able to meet the needs of industrial and residential customers.

Although deep and shallow well water is typically combined, lack of precipitation has hampered its grade.

"We are not keeping the quality of water we enjoy and depend upon," said City Manager Jim Patrick.

Although geotechnical information indicates water sources may be available north and west of the city, data is limited and dates back to the early 1900s. Upon obtaining easements from property owners, test drillings will be done at the Zylstra Property, Section 29 of Washington Township and the Bauer Property, Section 33 of Washington Township.

Three borings are planned, and easements will be paid at the rate of $500 apiece, funded through the Water Depreciation Funds.

Mobile drilling will bore 125 feet near anticipated shallow glacial wells and 500 feet near anticipated deep Dakota wells. If a well is found in deep locations, Rainforth said a test well will be installed, pumped and sampled.

Five shallow and three deep locations have been identified, with a combined cost of $150,000 for test borings and samplings.

Test borings and sampling will be performed at the rate of $6,000 per shallow location and $40,000 per deep location. Five shallow locations are projected for a combined cost of $30,000 and three deep locations are projected at a combined cost of $120,000.
