History of Source Water

Protection: Before 1985

Growing understanding of how human activities can impact drinking water and groundwater

John Snow first linked a London cholera outbreak (killing over 600 people) to drinking sewage from a well in 1855

In Iowa there was state-led water sampling, water system reviews, and drinking water protection efforts since early 1900s

By late 1970s many city wells in the old center of town, next to old businesses, and are also old

Federal Safe Drinking Water Act of 1974 established national drinking water standards for 23 contaminants (radium-226, nitrate, total coliform, etc.), with routine sampling

History of Source Water Protection

1985-1996

State level:

1987 Iowa Groundwater Protection Act

Prevent contamination of groundwater from point and

nonpoint source pollution, to the maximum extent practical

Established funding for management and creation of many state groundwater and pollution programs:

Center for Health Effects of Environmental Contamination (CHEEC)

(UI)

Iowa Waste Reduction Center (UNI)

Leopold Center for Sustainable Agriculture (ISU)

Etc.

Federal level (EPA):

1986 SDWA started EPA’s “Wellhead protection” program

Prevention of drinking water contamination is the primary goal

An exclusively community (locally)-led program. EPA funded,

developed and provided access to resources uch as guidebooks

and seminars to help communities begin wellhead protection.

Beginnings of terms such as WHPA, Capture Zones,

delineation, implementation, and 5-Step Planning Process

Not much federal $$ for implementation of program

Nationwide, only 600 water systems had started wellhead protection by 1993

1985-1996

Page 6: Source Water Protection in Iowa...Started Source Water Planning in 2009-2010 City has two shallow alluvial wells near South Raccoon River Nitrates around 3 ppm as N, as high as 4 ppm

History of Source Water Protection

1996-2003 1996 Amendments to SDWA

Provided funding to states through the Drinking Water

SRF program (15% of state set asides)

Changed name to Source Water Protection Program

(more inclusive, though some states still use “wellhead”

term for groundwater program)

Comprehensive State Source Water Program “Plans”

provided by each state for EPA approval by 1998

(Iowa’s was approved in 1999). Concepts in Iowa:

Voluntary Program

7-Step Planning Process

Source Water Assessments provided by state

Geologically defined Susceptibility

History of Source Water Protection

2004-2009

Era of SWP “Phase 2” Plans

In 2004, SWP “Phase 1” Assessments are “done”!!

Available online on ftp site as word documents

Not many communities picked up the SWP baton

themselves without state outside help.

~2003 IDNR expanded constracts with outside

agencies to assist community Phase 2 Plans:

Iowa Rural Water Association (IRWA)

Iowa Association of Municipal Utilities (IAMU)

History of Source Water Protection

2010-2014

2011: Implemented Needed Updates to Source

Water Assessments

Since 2004 there were over 500 changes to public wells

New wells

“New” Locations

New technology

LiDAR elevations

GIS Soils data

Better groundwater models

Better databases

Page 11: Source Water Protection in Iowa...Started Source Water Planning in 2009-2010 City has two shallow alluvial wells near South Raccoon River Nitrates around 3 ppm as N, as high as 4 ppm

2010: Iowa’s SWP Program split in two: Targeted and Non-Targeted

A Targeted Community:

Has identified a contaminant(s) that is trending upward

Nitrates above 5 mg/L and trending upward

Shallow alluvial wells that are highly susceptible

A willing community with willing stakeholders

Typically a groundwater investigation provided by IDNR

A Non-Targeted Community:

Any community in Iowa that is interested in Source Water Protection

Limited groundwater investigations, SWP Assessments

Publications of Guidebook, Workbook, GIS starter guides, Publishing SWP GIS Resources, Workshop seminars, Wellhead CRP zone change, Source Water SRF loan funding, Source Water Mapper, etc., etc.

Source Water Stories:

City of De Soto

Are we done with Source Water in De Soto now?

De Soto submitted their SWP Plan and Implementation efforts, and was

accepted as “Substantially Implemented” by the program in 2012

De Soto won AWWA Exemplary Source Water Protection Award in 2012

Landowner of converted row crop acres threatened remove native

vegetation and plant it all in corn again in 2014

Still an acttive Iowa DOT facility in wellhead area (with propane, diesel

fuel, oil, etc.) in the capture zone
